The TV controlling software for each program checks if a VPS CNI code is transmitted ( this system exists for German, Swiss and Austrian transmissions). If no VPS CNI code is found, then the system check if a CNI code is transmitted as part of the teletext transmission ( Packet 8/30 format 1 ). If such a code ( VPS or teletext ) is found and if this code is in the ATSS list, the program is automatically named. If the transmission does not have VPS CNI, and no teletext service is availab le, then there is no possibility of the program being automatically named. The programs found are then sorted in 4 groups : Group I : It contains all the pro grams from the selected country and named by the TV controlling software. Within this group the sorting order is fixed by the ATSS list. Group II : It contains all the pro grams with a strong signal strength which are not listed in group I. Group III : It contains all the pro grams with a weak signal strength which are not listed in group I. Group IV : If two or more programs with the same code are found, only the strongest ( or if they have the same level the one with the lowest frequency) is listed in group I, II or III. The others are listed in group IV.

X-RAY RADIATION PRECAUTION 1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid such hazards, the high voltage must not exceed the specified limit. The nominal value of the high voltage of this receiver is 26 KV (25” - 28”) at max beam curr ent. The high voltage must not, under any circumstances, exceed 29.5 KV (25") or 30 KV (28"). Each time a receiver requires servicing, the high voltage should be checked. It is important to use an accurate and reliable high voltage meter. 2. The only source of X-RAY Radiation in this TV receiver is the picture tube. For continued X-RAY RADIATION protection, the replacement tube must be exactly the same type tube as specified in the parts list. SAFETY PRECAUTION 1. Potentials of high voltage are present when this receiver is operating. Operation of the receiver outside the cabinet or with the back board removed involves a shock hazard from the receiver. 1) Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions necessary when working on high voltage equipment. 2) Discharge the high potential of the picture tube before handling the tube. The picture tube is highly evacuated and if broken, glass fragments will be violently expelled. 2. If any Fuse in this TV receiver is blown, replace it with the FUSE specified in the Replacement Parts List. 3. When replacing a high wattage resistor ( metal oxide film resistor) in the circuit board, keep the resistor 10 mm away from circuit board. 4. Keep wires away from high voltage or high temperature components. 5. This receiver must operate under AC 230 volts, 5O Hz. NEVER connect to DC supply or any other power or frequency. PRODUCT SAFETY NOTICE Many electrical and mechanical parts in this equipment have special safety-related characteristics. These characteristics are often passed unnoticed by a visual inspection and the X-RAY RADIATION protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this manual and its supplements, electrical components having such features are identified by designated symbol on the parts list. Before replacing any of these components, read the parts list in this manual carefully. The use of substitutes replacement parts which do not have the same safety characteristics as specified in the parts list may create X-RAY Radiation. - 13 - Service manual WP 895/895F, CP885/885F 3 - Alignment instructions 3-1 Microcontroller con figuration : Service mode To switch the TV set into service mode please see instruction below. 1 - Select pr. number 91 2 - Adjust sharpness to minimum and exit all menu. 3 - Quickly press the key sequence : RED - GREEN - menu To software version is displayed beside the word Service, e.g. “ SERVICE V1.00A ”.

The extraction of the data is performed in the digital domain. The first stage is to select and convert the analogue CVBS signal into a digital form. This is done using 8 bit ADC sampling at 20.25 Mhz. The digital data services transmitted in the VBI are selected and acquired separately form the video part. This is done by the use of an adaptive data slicer. The following data types can be extracted : 625 line World System Teletext (WST), VPS, WSS. The data is acquired and decoded by the teletext decoder (TPU), then stored in an SRAM lnterface. 4-1-9- Data Capture Features • Video Signal Quality detector • Data Capture for 625 line WST • Data Capture for VPS data (PDC system A) • Data Capture for Wide Screen Signalling (WSS) bit decoding • Real-time capture and decoding for WST Teletext in Hardware, to enable optimised microprocessor throughput • 10 page memory stored On-Chip - 20 - Service manual WP 895/895F, CP885/885F • Inventory of transmitted Teletext pages stored in the Page Table • Signal quality detector for WST data • Comprehensive Teletext language coverage • Full Field Vertical Blanking Interval (VBI) data capture of WST data 4-1-10- TV processor version and -Controller capacity IC version VCT 3832A VCT 3834A 96k 1k 96k 1k 10 pages X 10 pages 8 bit -controller ROM size RAM size PAL decoder SECAM decoder NTSC decoder Picture improvement Teletext page memory Adaptive Comb filter Panorama Scaler 4-1-11- IC marking and version Chassis IC marking CP885 VCT3832A CP885F VCT3834A WP895F VCT3834A WP895 VCT3834A OSD languages Text ATSS countries English, French, German, Italian, Spanish, Dutch, Danish, Finnish, Norwegian, Swedish, Greek, Polish, Hungarian, Czech, Slovakian, Romanian, Russian.

The systems allow two high-quality digital sound channels to be added to the already existing FM/AM-channel. The sound coding follows the format of the so-called Near Instantaneous Companding System (NICAM 728). Transmission is performed using Differential Quadrature Phase Shift Keying (DQPSK. Table below offers an overview of the modulation parameters.) In the case of NICAM/FM (AM) mode, there are three different audio channels available: NICAM A, NICAM B, and FM/AM-mono. NICAM A and B may belong either to a stereo or to a dual language transmission. Information about operation mode and about the quality of the NICAM signal can be read by the controlling software via the control bus. In the case of low quality (high bit error rate), the controlling software may decide to switch to the analogue FM/AMmono sound. Alternatively, an automatic NICAM-FM/AM switching may be applied. 4-2-1-5 German 2-Carrier System (DUAL FM System) Since September 1981, stereo and dual sound programs have been transmitted in Germany using the 2-carrier system. Sound transmission consists of the already existing first sound carrier and a second sound carrier additionally containing an identification signal. More details of this standard are given in Tables below. For D/K very similar system is used. - 25 - Service manual WP 895/895F, CP885/885F TV standards TV system B/G B/G Position of sound carrier (MHz) 5.5 / 5.7421875 5.5 / 5.85 L I D/K 6.5 / 5.85 6.0 / 6.552 6.5 / 6.2578125 D/K1 6.5 / 6.7421875 D/K2 6.5 / 5.85 D/K-NICAM Sound modulation Color system Country FM Stereo FM-Mono / NICAM PAL PAL AM-Mono / NICAM FM-Mono / NICAM FM Stereo SECAM-L PAL SECAM-East Germany Scandinavia, Spain France UK USSR FM-Mono / NICAM Architecture of MSP341x Pin connections and short description Pin No. Pin Name Type 1 TP Out 2 NC 3 NC 4 TP Out 5 TP Out 6 ADR_SEL In 7 STANDBYQ In 8 NC 9 I2C_CL In / Out 10 I2C_DA In / Out 11 TP In / Out Short description Test pin Not Connected Not Connected Test pin Test pin I2C bus Address select Standby ( Low-active) Not Connected I2C Clock I2C data Test pin - 26 - Hungary Service manual WP 895/895F, CP885/885F Pin No. 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 Pin Name TP TP NC TP TP TP DVSUP DVSS NC NC NC NC RESETQ NC NC VREF2 DACM_R DACM_L NC TP NC NC NC VREF1 SC1_OUT_R SC1_OUT_L NC AHVSUP CAPL_M AHVSS AGNDC NC NC NC NC NC ASG2 SC2_IN_L SC2_IN_R ASG1 SC1_IN_L SC1_IN_R VREFTOP MONO_IN AVSS AVSUP ANA_IN1+ Type In / Out Out Out Out Out In Out Out Out Out Out In In In In In Short description Test pin Test pin Not Connected Test pin Test pin Test pin Digital power supply +5V Digital Ground Not Connected Not Connected Not Connected Not Connected Power-On-reset Not Connected Not Connected Reference ground 2 high voltage part Loudspeaker out Right Loudspeaker out Left Not Connected Test pin Not Connected Not Connected Not Connected Reference ground 1 high voltage part Scart output 1, right Scart output 1, left Not Connected Analog power supply 8.0V Volume capacitor MAIN Analog ground Analog reference voltage high voltage part Not Connected Not Connected Not Connected Not Connected Not Connected Analog Shield Ground 2 Scart input 2 in, left Scart input 2 in, right Analog Shield Ground 1 Scart input 1 in, left Scart input 1 in, right Reference voltage IF A/D converter Mono input Analog ground Analog power supply In IF input 1 - 27 - Service manual WP 895/895F, CP885/885F Pin No. 59 60 61 62 63 64 Pin Name ANA_IN1NC TESTEN XTAL_IN XTAL_OUT NC Type In In In Out Short description IF common Not Connected Test pin Crystal oscillator Crystal oscillator Test pin 4-3 TDA 4470-Multistandard Video-IF and Quasi Parallel Sound Processor 4-3-1- Description The TDA 4470 is an integrated bipolar circuit for multi-standard video/sound IF (VIF/SIF) signal processing in TV/VCR and multimedia applications.

The output signal of the VIF amplifier is applied to the FPLL carrier generation and the video demodulator. - 42 - Service manual WP 895/895F, CP885/885F SAW filters Ref.

Therefore, in the case of all negative modulated signals (e.g., B/G standard) the sync. level of the demodulated video signal is the criterion for a fast charge/discharge of the AGC capacitor. For positive modulation (e.g., L standard) the peak white level of video signal controls the charge current. In order to reduce reaction time for positive modulation, where a large time constant is needed, an additional black level detector controls the discharge current in the event of decreasing VIF input signal. The control voltage (AGC voltage at Pin 8) is transferred to an internal control signal, and is fed to the tuner AGC to generate the tuner AGC current at Pin 11 (open collector output). The take over point of the tuner AGC can be adjusted at Pin 10 by a potentiometer or an external dc voltage (from interface circuit or microprocessor). 5-2-4 FPLL, VCO and AFC The FPLL circuit (frequency phase locked loop) consists of a frequency and phase detector to generate the control voltage for the VCO tuning. In locked mode, the VCO is controlled by the phase detector and in unlocked mode, the frequency detector is superimposed. The VCO operates with an external resonance circuit (L and C parallel) and is controlled by internal varicaps. The VCO control voltage is also converted to a current and represents the AFC output signal at Pin 22. At the AFC switch (Pin 19) three operating conditions of the AFC are possible: AFC curve “rising” or “falling” and AFC “off”. A practicable VCO alignment of the external coil is the adjustment to zero AFC output current at Pin 22. At center frequency the AFC output current is equal to zero. Furthermore, at Pin 14, the VCO center frequency can be switched for setting to the required L’ value (L’ standard). The optional potentiometer at Pin 26 allows an offset compensation of the VCO phase for improved sound quality (fine adjustment). Without a potentiometer (open circuit at Pin 26), this offset compensation is not active. The oscillator signal passes a phase shifter and supplies the in-phase signal (0o) and the quadrature signal (90o) of the generated picture carrier. - 43 - Service manual WP 895/895F, CP885/885F 5-2-5 Video Demodulation and Amplifier The video IF signal, which is applied from the gain controlled IF amplifier, is multiplied with the in-phase component of the VCO signal. The video demodulator is designed for low distortion and large bandwidth. The demodulator output signal passes an integrated low pass filter for attenuation of the residual vision carrier and is fed to the video amplifier. The video amplifier is realised by an operational amplifier with internal feedback and 8 MHz bandwidth (–3 dB). A standard dependent dc level shift in this stage delivers the same sync. level for positive and negative modulation. An additional noise clipping is provided. The video signal is fed to VIF-AGC and to the video output buffer. This amplifier with a 6 dB gain offers easy adaptation of the sound trap. For nominal video IF modulation the video output signal at Pin 12 is 2 Vpp. 5-2-6 Sound IF Amplifier and SIF-AGC The SIF amplifier is nearly identical with the 3-stage VIF amplifier. Only the first amplifier stage exists twice and is switchable by a control voltage at Pin 3. Therefore with minimal external expense it is possible to switch between two different SAW filters. Both SIF inputs features excellent cross-talk attenuation and an input impedance which is independent from the switching condition. The SIF-AGC is related to the average level of AM- or FM-carrier and controls the SIF amplifier to provide a constant SIF signal to the AM demodulator and QPS mixer. 5-2-7 Quasi-Parallel-Sound (QPS) Mixer The QPS mixer is realised by a multiplier. The SIF signal (FM or NICAM carrier) is converted to the intercarrier frequency by the regenerated picture carrier (quadrature signal) which is provided from the VCO. The intercarrier signal is fed via an output amplifier to Pin 24. 5-2-8 Standard Switch To have equal polarity of the video output signal the polarity can be switched in the demodulation stage in accordance with the TV standard. Additionally a standard dependent dc level shift in the video amplifier delivers the same sync. level. In parallel to this, the correct VIF-AGC is selected for positive or negative modulated VIF signals. In the case of negative modulation (e.g., B/G standard) the AM output signal is switched off. For positive modulation (L standard) the AM demodulator and QPS mixer is active. This condition allows a parallel operation of the AM sound signal and the NICAM-L stereo sound. 5-2-9 L’ Switch With a control voltage at Pin 14 the VCO frequency can be switched for setting to the required L’ value (L’ standard). Also a fine adjustment of the L’-VCO center frequency is possible via a potentiometer. The L’ switch is only active for positive modulated video IF-signals (standard switch in L mode). 5-2-10 Internal Voltage Stabiliser The internal bandgap reference ensures constant performance independent of supply voltage and temperature. - 44 - Service manual WP 895/895F, CP885/885F 5-3 Video - VCT description 5-3-1 Introduction The VCT 38xxA includes complete video, display, and deflection processing. All processing is done digitally, the video front-end and video back-end are interfacing to the analogue world. Most functions can be controlled by software via I 2 C bus slave interface. 5-3-2 Video Front-end This block provides the analogue interfaces to all video inputs and mainly carries out analogue-to-digital conversion for the following digital video processing. Most of the functional blocks in the front-end are digitally controlled (clamping, AGC, and clock-DCO). The control loops are closed by the Fast Processor (‘FP’) embedded in the video decoder. 5-3-3 Input Selector Up to seven analogue inputs can be connected. Four inputs are for input of composite video or S-VHS luma signal. These inputs are clamped to the sync back porch and are amplified by a variable gain amplifier. Two chroma inputs can be used for connection of S-VHS carrier-chrominance signal. These inputs are internally biased and have a fixed gain amplifier. 5-3-4 Clamping The composite video input signals are AC-coupled to the IC. The clamping voltage is stored on the coupling capacitors and is generated by digitally controlled current sources. The clamping level is the back porch of the video signal. S-VHS chrominance is also AC-coupled. The input pin is internally biased to the center of the ADC input range. Each channel is sampled at 10.125 MHz with a resolution of 8 bit. 5-3-5 Automatic Gain Control A digitally working automatic gain control adjusts the magnitude of the selected baseband. 5-3-6 Digitally Controlled Clock Oscillator The clock generation is also a part of the analogue front-end. The crystal oscillator is controlled digitally by the control processor. The clock frequency can be adjusted within ±150 ppm. This adjustment is done in factory for every TV set. 5-3-7 Analogue Video Output The input signal of the Luma ADC is available at the analogue video output pin (#11). The signal at this pin is buffered by a source follower. The output voltage is 2 V. The magnitude is adjusted with an AGC in 8 steps together with the main AGC. - 45 - Service manual WP 895/895F, CP885/885F 5-3-8 Adaptive Comb Filter (VCT3834A only) The adaptive comb filter is used for high-quality luminance/chrominance separation for PAL or NTSC signals. The comb filter improves the luminance resolution (bandwidth) and reduces interferences like cross-luminance and cross-color artefacts. The adaptive algorithm can eliminate most of the mentioned errors without introducing new artefacts or noise. The filter uses two line delays to process the information of three adjacent video lines. To have a fixed phase relationship of the colour subcarrier in the three channels, the system clock (20.25 MHz) is fractionally locked to the colour subcarrier. This allows the processing of all colour standards and substandards using a single crystal frequency. The CVBS signal in the three channels is filtered at the subcarrier frequency by a set of bandpass/ notch filters. The output of the three channels is used by the adaptation logic to select the weighting that is used to reconstruct the luminance/chrominance signal from the 4 bandpass/notch filter signals. By using soft mixing of the 4 signals switching artefacts of the adaption algorithm are completely suppressed. The comb filter uses the middle line as reference, therefore, the comb filter delay is one line. If the comb filter is switched off, the delay lines are used to pass the luma/ chroma signals from the A/D converters to the luma/ chroma outputs. Thus, the comb filter delay is always one line. 5-3-9 Color Decoder In this block, the standard luma/chroma separation and multi-standard colour demodulation is carried out. The colour demodulation uses an asynchronous clock, thus allowing a unified architecture for all colour standards. The colour killer uses the burst-phase/ burst-frequency measurement to identify a PAL/NTSC or SECAM colour signal. For PAL/NTSC, the colour is switched off (killed) as long as the colour subcarrier PLL is not locked. For SECAM, the killer is controlled by the toggle of the burst frequency. The burst amplitude measurement is used to switch-off the colour if the burst amplitude is below a programmable threshold. Thus, colour will be killed for very noisy signals. The colour amplitude killer has a programmable hysteresis. The burst-frequency measurement is also used for automatic standard recognition (together with the status of horizontal and vertical locking) thus allowing a completely independent search of the line and colour standard of the input signal. The following standards can be distinguished: PAL B,G,H,I; NTSC M; SECAM; NTSC 44; PAL M; PAL N; PAL 60. In AV mode or when Prg No 0 is selected all the standards above are enabled by the controlling software. In INSTALL menu the controlling software enables PAL B,G, H,I and SECAM detection. The colour standard for each program number is stored in EEPROM. Outside INSTALL menu and for programmes numbers 1 to 99, the auto colour detection is disabled, the colour standard is recall from EEPROM and forced. 5-3-10 Horizontal Scaler (VCT3834A only) The 4:2:2 YC r C b signal from the colour decoder is processed by the horizontal scaler. The scaler block allows a linear or nonlinear horizontal scaling of the input video signal in the range of 0.25 to 4. Nonlinear scaling, also called “Panoramavision”, provides a geometrical distortion of the input picture. It is used to fit a picture with 4:3 format on a 16:9 screen by stretching the picture geometry at the borders. Also, the inverse effect can be produced by the scaler. The scaler contains a programmable decimation filter, a 1-line FIFO memory, and a programmable interpolation filter. - 46 - Service manual WP 895/895F, CP885/885F 5-3-11 Video Sync Processing To extract the sync information from the video signal, a linear phase low-pass filter eliminates all noise and video contents above 1 MHz. The sync is separated by a slicer; the sync phase is measured. A variable window can be selected to improve the noise immunity of the slicer. The phase comparator measures the falling edge of sync, as well as the integrated sync pulse. The sync phase error is filtered by a phase-locked loop that is computed by the Fast Processor. All timing in the front-end is derived from a counter that is part of this PLL, and it thus counts synchronously to the video signal. A separate hardware block measures the signal back porch and also allows gathering the maximum/minimum of the video signal. This information is processed by the FP and used for gain control and clamping. For vertical sync separation, the sliced video signal is integrated. The FP uses the integrator value to derive vertical sync and field information. The information extracted by the video sync processing is multiplexed onto the hardware front sync signal (FSY) and is distributed to the rest of the video processing system. The data for the vertical deflection, the sawtooth, and the East-West correction signal is calculated by the VCT 38xxA. 5-3-12 Display Processing In the display processing the conversion from digital YC r C b to analogue RGB is carried out. In the luminance processing path, contrast and brightness adjustments and a variety of features, such as black-level expansion, dynamic peaking and soft limiting, are provided. In the chrominance path, the C r C b signals are converted to 4:4:4 format and filtered by a colour transient improvement circuit. The YC r C b signals are converted by a programmable matrix to RGB colour space. The digital OSD insertion circuit allows the insertion of a 5-bit OSD signal. The OSD signals and the display clock are synchronised to the horizontal flyback. 5-3-13 Chroma Transient Improvement The intention of this block is to enhance the chroma resolution. A correction signal is calculated by differentiation of the colour difference signals. The differentiation can be selected according to the signal bandwidth, e.g. for PAL/NTSC/ SECAM or digital component signals, respectively. The amplitude of the correction signal is adjustable. Small noise amplitudes in the correction signal are suppressed by an adjustable coring circuit. To eliminate ‘wrong colours’, which are caused by over and undershoots at the chroma transition, the sharpened chroma signals are limited to a proper value automatically. 5-3-14 Video Back-end The digital RGB signals are converted to analogue RGBs using three video digital-to-analogue converters (DAC) with 10-bit resolution. An analogue brightness value is provided by three additional DACs. The adjustment range is 40 % of the full RGB range. Controlling the white-drive/analogue brightness and also the external contrast and brightness adjustments is done via the Fast Processor, located in the front-end. Control of the cutoff DACs is done via I 2 C bus registers. Finally cutoff and blanking values are added to the RGB signals. Cutoff (dark current) is provided by three 9bit DACs. The adjustment range is 60 % of full scale RGB range. The analogue RGB-outputs are current outputs with current-sink characteristics. The maximum current drawn by the output stage is obtained with peak white RGB. An external half contrast signal can be used to reduce the output current of the RGB outputs to 50% . Cutoff and whitedrive current measurement are carried out during the vertical blanking interval. They always use the small bandwidth setting. - 47 - Service manual WP 895/895F, CP885/885F 5-3-15 CRT Measurement and Control The display processor is equipped with an 8-bit ADC for all measuring purposes. The ADC is connected to the SENSE input pin. Cutoff and white-drive current measurement are carried out during the vertical blanking interval. 5-3-16 Average Beam Current Limiter The average beam current limiter (BCL) uses the SENSE input for the beam current measurement. The BCL uses a different filter to average the beam current during the active picture. The filter bandwidth is approx. 2 kHz. The beam current limiter has an automatic offset adjustment that is active two lines before the first cutoff measurement line. The beam current limiter function is located in the front-end. The data exchange between the front-end and the back-end is done via a single-wire serial interface. The beam current limiter allows the setting of a thresh-old current. If the beam current is above the threshold, the excess current is low-pass filtered and used to attenuate the RGB outputs by adjusting the white-drive multipliers for the internal (digital) RGB signals, and the analogue contrast multipliers for the analogue RGB inputs, respectively. The lower limit of the attenuator is programmable, thus a minimum contrast can always be set. During the tube measurement, the ABL attenuation is switched off. After the white-drive measurement line it takes 3 lines to switch back to BCL limited drives and brightness. 5-3-17 Analogue RGB Insertion The VCT 38xxA allows insertion of external analogue RGB signals. The RGB signal is key-clamped and inserted into the main RGB by the Fast-Blank switch. The external RGB input can be overlaid or underlaid to the digital picture. The external RGB signals can be adjusted independently as regards DC level (brightness) and magnitude (contrast). All signals for analogue RGB insertion (RIN, GIN, BIN, FBLIN) must be synchronised to the horizontal flyback, otherwise a horizontal jitter will be visible. The VCT 38xxA has no means for timing correction of the analogue RGB input signals. RGB signals are not digitalised and therefore cannot be processed by the picture scaler. 5-3-18 Fast-Blank Monitor The presence of external analog RGB sources can be detected by means of a Fast-Blank monitor. With a special monitor logic it is possible to detect if there is an external RGB source active and if it is a full screen insertion or only a box. The monitor logic is connected directly to the FBLIN pin. The controlling software uses this information to disable all picture format using display scaler. 5-3-19 Vertical and East/West Deflection The calculations of the vertical and East/West deflection waveforms is done by the internal Fast Processor (FP). The algorithm uses a chain of accumulators to generate the required polynomial waveforms. To produce the deflection waveforms, the accumulators are initialised at the beginning of each field. The initialisation values must be computed by the TV control processor and ar e written to the front-end once. - 48 - Service manual WP 895/895F, CP885/885F 5-3-20 EHT Compensation The vertical waveform can be scaled according to the average beam current. This is used to compensate the effects of electric high-tension changes due to beam current variations. EHT compensation for East/West deflection is done with an offset corresponding to the average beam current. 5-3-21 Reset Function Reset of all VDP functions is performed by the RESQ pin. When this pin becomes active, all internal registers and counters are lost. 5-3-22 Standby and Power-On The VDP does not have a standby mode. To disable all the analogue and digital video functions, it is necessary to switch off the supplies for analogue front-end (VSUP AF ), analogue back-end (VSUP AB ) and digital circuitry (VSUP D ). 5-4- Microcontroller 5-4-1 Introduction The TV controller basically consists of the CPU, RAM, ROM, and a number of peripheral modules. For instance: – a memory banking module is included to allow access to more than 64 kB memory. – a bootloader software is included to allow in-system-downloading of external code to Flash memory via the I 2 C interface. The TV controller runs the complete software necessary to control a TV set. The software includes control of the audio, video, OSD, and text processors on chip, as well, as control of external devices like tuner or stereo decoder. Communication between the TV controller and external devices is done either via I 2 C bus interface or via programmable port pins. The TV Controller is clocked with f OSC = f XTAL /2. 5-4-2 CPU The CPU is fully compatible to WDC’s W65C02 micro-processor. The processor has 8-bit registers/accumulator, an 8bit data bus, and a 16-bit address bus. - 49 - Service manual WP 895/895F, CP885/885F 5-4-3 - Controller I/O pin configuration and function There exist different kinds of ports. The universal ports serve as digital I/O and have additional special input and output functions. A subset of the universal ports serves as input for the analogue-to-digital converter. - Controller I/O pin configuration and function table 1 2 Power AGC configuration Stand by TV ON Push Pull Low Push Pull High High impedance High impedance 5 Mod SW High impedance Push Pull 6 7 8 9 SECAM L’ AFC IR SC1 SW High impedance High impedance High impedance High impedance Push Pull High impedance High impedance High impedance 10 SC2 SW High impedance High impedance 61 62 63 Mute LED KB Push Pull Open Drain High impedance Push Pull Open Drain High impedance 64 OCP High impedance High impedance pin name description Switch OFF / ON SMPS Tuner AGC level input – For factory use only High = Negative modulation, Low = Positive modulation (L/L’).

To reduce power consumption in stand by mode all ports not used are configured in high impedance mode. 5-4-4 Tuning The AFC information is supplied by the demodulator IC, and becomes available on VCT pin 7 for controlling software. The controlling software uses this information for tuner frequency tracking ( automatic following ). The AFC window is typically between 50 KHz and 100 KHz. The minimum frequency step of the tuner is 50 Khz. This AFC function is disabled when a program is tuned using the direct frequency entry or after fine tuning adjustment. Therefore it is recommended to tune channel with the TV search function ( manual or ATSS ) or using the direct channel entry to enable the Automatic Frequency Control. 5-4-5 Automatic Format switching and WSS When AUTO mode is selected by the user, the television will automatically select a mode for the user. The format information is supplied by SCART pin 8 level when in AV mode or by WSS data. The signal contains codes as defined in the WSS European Telecommunication Standard, ETS 300 294. Briefly, the signal is received at the beginning of line - 50 - Service manual WP 895/895F, CP885/885F 23, in each frame. This is bi-phase encoded using a clock frequency of 5 MHz. In total, 14 data bits are available, in 4 groups. Group 1 contains the codes for the received format. The mode chosen is defined by the following table. In effect the default mode is full screen. The table below gives a summary of the FORMAT modes available (for WP895 and WP895F), and their given properties.

Service manual WP 895/895F, CP885/885F The following schematic, illustrates the logic of control for the two SCART connectors. The terms used in the schematic are described below ; 1. AUTO represents a situation where the television has self-selected its picture source. This could be when the SCART SLOW SWITCHING pin has gone to a high state, and the AV 1 input is selected without the intervention of the user. 2. FORCED represents the change of source which has been commanded by the user (using the EXTERNAL button). The user always has priority, and can override the AUTO change of source by the television. 3. AV KEY represents the EXTERNAL button of the remote control, or on the television. 4. S/SW 1, or S/SW 2 represent the SLOW SWITCHING inputs of the first SCART (AV 1) or second SCART (AV 2), these each being pin number 8. 5. F/SW 1 represents the FAST SWITCHING input of the first SCART (AV 1), on pin number 16. The second SCART, AV 2, input does not possess a FAST SWITCHING input. The HIGH state of a slow switching input represents the request from the external source to be selected by the television. Whether this is accepted or not depends on the position in the logic diagram. The general rule is that the user always has priority, so the use of the AV KEY will always result in a defined logic path being followed. Under certain circumstances, defined in the diagram, the change of state of a slow switching input will result in the automatic change of source by the television. This change, such as the change from RF broadcast to the AV 1 input, - 52 - Service manual WP 895/895F, CP885/885F can always be overridden by the user after the event. Each line on the diagram, with its associated text, represents the exact conditions under which the change of state will occur. Sometimes this will be accompanied by another action which will be automatically performed by the television, being to either ENABLE or DISABLE F/SW 1. 5-4-7 Over Current Protection In case of overload, the SMPS secondary voltages will drop. The voltage on pin 64 of microcontroller drops below a reference voltage (2.26V). The controlling software which continuously monitors this voltage will switch the set to stand by mode. To power on the set again the user must switch it off using the main power switch. Appropriate hysteresis guaranrees a reliable operation. 5-5 Teletext Display National character option bits C12, C13, C14 are transmitted in the page header of a given teletext page. The national option bits are intended to change (or exchange) 13 characters within the G0 character set, according to the needs of each national language. However, for Cyrillic and Greek languages, a major character set change (a change of character mapping) needs to effected for correct display. These codes represent, for a given broadcaster, the intended language that the teletext page should be displayed in. As there are only 3 bits, there are only 8 codes available to cover all the possible language combinations. This means that for a received code there are several possibilities meanings, and therefore several possibilities for display. This is not as bad as it first seems, as we use the user-selected OSD language to identify the intention of the broadcaster. For example, a user wishing to see Russian teletext should select Russian OSD language, otherwise he would not have correct teletext display on the TV. The table below allows the reader to understand the relationship between selected OSD language (which is under user control), the teletext language display (selected by national option bits in transmission page header) and the language mapping (either Latin or Greek/Cyrillic) An example: For Greek teletext display, (if national option code 1 1 1 is received from the broadcaster), the user should select the Greek OSD language. Even if English, French, German, Italian, Spanish, Dutch, Danish, Finnish, Norwegian or Swedish OSD languages are selected, the teletext will be correctly displayed. However, if Polish, Hungarian, Czech, Slovakian, Rumanian or Russian OSD are selected, Latin font mapping is selected. The consequence will be incorrect teletext display, with NO GREEK CHARACTERS DISPLAYED. Romanian national font options will be selected. - 53 - Service manual WP 895/895F, CP885/885F OSD Language C 12 English, French, 0 German, Italian, 0 Spanish, Dutch, 0 Danish, Finnish, 0 1 Norwegian, Swedish, Greek 1 1 1 0 Polish, 0 Hungarian, 0 Czech, 0 Slovakian, 1 Rumanial 1 1 1 0 Russian 0 0 0 1 1 1 1 C 13 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1 C 14 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 Teletext Language English German Swedish/Finnish Italian French Spanish Turkish English Polish German Hungarian Lettish/Lithuanian French Serb/Croat/Slovenian Czech/Slovak Rumanian English German Estonian Lettish/Lithuanian English English Czech/Slovak Rumanian ESC Teletext Language English German Swedish/Finnish Italian French Spanish Turkish Greek Polish German Hungarian Lettish/Lithuanian French Serb/Croat/Slovenian Czech/Slovak Rumanian Serbian/Montenegrin German Estonian Lettish/Lithuanian Russian/Bulgarian Ukrainian Czech/Slovak Rumanian Mapping Latin Latin Latin Latin Latin Latin Latin Greek/Cyrillic Latin Latin Latin Latin Latin Latin Latin LatinRussian Greek/Cyrillic Latin Latin Latin Greek/Cyrillic Greek/Cyrillic Latin Latin 5-6 Sound processing 5-6-1 Analogue sound IF - input section The input pins ANA_IN1+ and ANA_IN- offer the possibility to connect sound IF sources to the MSP 341xD. The analogue-to-digital conversion of the preselected sound IF signal is done by an A/D converter, whose output is used to control an analogue automatic gain circuit (AGC), providing an optimal level for a wide range of input levels. 5-6-2 Quadrature Mixers The digital input coming from the integrated A/D converter may contain audio information at a frequency range of theoretically 0 to 9 MHz corresponding to the selected standards. By means of two programmable quadrature mixers, two different audio sources ; for example, NICAM and FM-mono, may be shifted into baseband position. 5-6-3 Phase and AM discrimination The filtered sound IF signals are demodulated by means of the phase and amplitude discriminator block. On the output, the phase and amplitude is available for further processing. AM signals are derived from the amplitude information, whereas the phase information serves for FM and NICAM demodulation. - 54 - Service manual WP 895/895F, CP885/885F 5-6-4 NICAM decoder In case of NICAM - mode, the phase samples are decoded according the DQPSK - coding scheme. The output of this block contains the original NICAM bitstream. 5-6-5 DSP section All audio baseband functions are performed by digital signal processing (DSP). The DSP section controls the source and output selection, and the signals processing. 5-6-6 Sound Mode switching In case of NICAM transmission, the controlling software reads the bit error rate and the operation mode from the NICAM Decoder. When the set is in “Auto detection” mode ( default mode after ATSS ) the controlling software sets automatically the sound mode ( NICAM mono, NICAM Dual 1 or NICAM Dual 2 ) depending on the transmitted mode. In the case of 2 Carrier FM transmission, the controlling software read the transmission mode and the signal quality level from the Stereo Detection Register. When the set is in “Auto detection” mode the controlling software automatically sets the sound mode ( mono, Stereo, Dual 1, Dual 2 ) depending on the transmitted mode. In “Auto detection” mode the controlling software evaluates the signal quality and automatically switches to the analogue sound carrier 1, if the transmission quality is too poor. To avoid unwanted automatic switching the threshold levels mono to stereo and stereo to mono are different. In “forced mono “ mode ( Red OSD in status Display Window), the controlling software configures the MSP341xD to demodula te onl y the analogue (FM or AM) sound carrier 1, no matter the signal quality. The sound mode “ forced “ or “ Autodetect” is stored for each programme. 5-7 Sound amplification The TDA8944J (TDA8946J) is a stereo BTL audio amplifier capable of delivering 2 x 7 W (2 x 15 W) output power to an 8 W load at THD = 10%, using a 12 V power supply and an external heatsink. The voltage gain is fixed at 32dB. With the three-level MODE input the device can be switched from ‘standby’ to ‘mute’ and to ‘operating’ mode. The TDA 8944J outputs are protected by an internal thermal shutdown protection mechanism and short-circuit protection. 5-7-1 Power amplifier The power amplifier is a Bridge Tied Load (BTL) amplifier with an all-NPN output stage, capable of delivering a peak output current of 1.5 A. The BTL principle offers the following advantages : - Lower peak value of the supply current. - The ripple frequency on the supply voltage is twice the signal frequency. - No DC-blocking capacitor - Good low frequency performance - 55 - Service manual WP 895/895F, CP885/885F 5-7-2 Mode selection The TDA894xJ has several functional modes, which can be selected by applying the proper DC voltage to pin MODE. Mute : In this mode the amplifier is DC biased but not operational (no audio output). This allows the input coupling capacitors to be charged to avoid pop-noise. The device is in mute mode when 2.5 V < VMODE < (Vcc-1.5 V). Operating : In this mode the amplifier is operating normally. The operating mode is activated at VMODE < 0.5 V. 5-8 Vertical deflection The vertical driver circuit is a bridge configuration. The deflection coil is connected between the output amplifiers, which are driven in phase opposition. The differential input circuit is voltage driven. The input circuit is especially intended for direct connection to driver circuits which deliver symmetrical current signals, but is also suitable for asymmetrical currents. The output current of these devices is converted to voltages at the input pins via resistors R350 and R351. The differential input voltage is compared with the output current through the deflection coils measured as voltage across R398, which provides internal feedback information. The voltage across R398 is proportional to the output current. 5-8-1 Flyback voltage The flyback voltage is determined by an additional supply voltage Vflb. The principle of operation with two supply voltages (class G) makes it possible to fix the supply voltage Vp optimum for the scan voltage and the second supply voltage Vflb optimum for the flyback voltage. Using this method, very high efficiency is achieved. The supply voltage Vflb is almost totally available as flyback voltage across the coil, this being possible due to the absence of a coupling capacitor. 5-8-2 Protection The output circuit has protection circuits for : - Too high die temperature - overvoltage of output stage A 5-8-3 Guard circuit The guard signal is not used. 5-8-4 Damping resistor For HF loop stability a damping resistor (R331) is connected across the deflection coil. 5-8-5 EAST-WEST Amplifier (TDA8358J) The East-West amplifier is current driven. It can only sink currents of the diode modulator circuit. A feedback resistor R397 is connected between the input and output of this inverting amplifier in order to convert the East-West correction input into an output voltage. - 56 - Service manual WP 895/895F, CP885/885F 5-9 Power supply (STR F6654) 5-9-1 STR-F6654 general description The STR-F6654 is an hybrid IC with a build-in MOSFET and control IC, designed for flyback converter type switch mode power supply applications. 5-9-2 Power supply primary part operations An oscillator generates pulses signals which turn on and off a MOSFET transistor. 5-9-2-1 Start-up circuit : VIN The start-up circuit is used to start and stop the operation of the control IC, by detecting a voltage appearing at VIN pin (pin 4). - 57 - Service manual WP 895/895F, CP885/885F When the power switch is pushed on, VIN increases slowly. During this time, C806 is charged through R802. As soon as VIN reaches 16V, the STR-F6654 control circuit starts operating. Then, VIN is obtained by smoothing the winding voltage which appears between pin6 and pin7 of the SMPS transformer. As this winding voltage does not increase to the set voltage immediately after the control circuit starts operating, VIN starts dropping. However, as this winding voltage reaches the set value before VIN voltage drops to the shutdown voltage (at 11V), the control circuit continues operating (see below VIN voltage at start-up). R805 resistor prevents that VIN pin voltage varies according to the secondary side output current. VIN must be set higher than the shutdown voltage (VIN (off) = 11Vmax) and lower than the O.V.P.

At the same time, the voltage at pin 1 (OCP / FB) increases with the same waveform as the MOSFET drain current. When the pin 1 voltage reaches the threshold voltage VTH1 = 0.73V, the STR-F6654 internal comparator 1 starts operating. The STR-F6654 internal oscillator is inverted and the MOSFET turns OFF. When the MOSFET turns OFF, charging of STR-F6654 internal capacitor C1 is released and C1 starts discharging by the STR-F6654 internal resistance R1. So, C1 voltage starts falling in accordance with the gradient regulated by the constant discharging time of C1 and R1. So, this means that the fixed time determined by C1 and R1 is the OFF-time of the MOSFET. When C1 voltage falls to around 3.7V, the STR-F6654 internal oscillator is reversed again and the MOSFET turns ON. C1 is quickly charged to around 6.5V The MOSFET continues to oscillate by repeating the above procedure. 5-9-2-3 STR-F6654 protection circuits • overcurrent protection function (OCP) Overcurrent protection is performed pulse by pulse detecting at STR-F6654 pin 1 (OCP) the peak of the MOSFET drain current in every pulse. • latch circuit This circuit sustains an output low from the STR-F6654 internal oscillator and stops operation of the power supply when overvoltage protection (OVP) and thermal shutdown (TSD) circuit are under operation • thermal shutdown circuit (TSD) This circuit triggers the latch circuit when the frame temperature of STR-F6654 IC exceeds 140°C • overvoltage protection circuit (OVP) This circuit triggers the latch circuit when the Vin voltage exceeds 22V (typ.) - 60 - Service manual WP 895/895F, CP885/885F 5-10 TV start-up, TV normal run and stand by mode operations 5-10-1 TV start-up operations * Schematic diagram for start-up operations * TV start-up and microcontroller initialisation - When SW801 power switch is pushed, main AC voltage is applied to T801 transformer (after rectification by D801...

So, Q808 is not conducting and Q807 is conducting - So, Q807 collector is connected to the ground and I810 controlled rectifier gate pin is set to low (no conducting) • So, current from 14V DC voltage (from T801 SMPS transformer pin 13) does not flow through Q811 and Q810 transistors but flows through I806 IC error amplifier - Q809 is conducting. So, Q810 is not conducting and no current flows from Q810 collector to the ground Therefore, the power circuit diagram is the following one : * power supply circuit diagram during TV set normal run - 63 - Service manual WP 895/895F, CP885/885F * power supply functioning during TV set normal run mode - I801 transmits controlled pulses to T801 which generates DC voltages after rectifications by secondary part diodes and electro capacitors (by example by D820 and C813 on 143V supply voltage line). - 8V, 5V, 3.3V supply voltage lines have stabilized voltages obtained by I820, I822, I823 voltage regulators. - On 143V supply voltage line, R823 resistor has been chosen to reach exact DC voltage required on this line. - 143V supply voltage line includes an IC error amplifier (I806) which corrects unexpected DC voltage variations on this line. * power supply IC delivery during TV set normal run power supply line 143V IC power supply delivery FBT 14.5V 14V 8V I602 sound amplifier pins 3-16 T401 H- drive I501 Main IC pins 14-39 I601 Sound Demod pins 38-39-40 I703 IR receiver pin 1 I501 Main IC pins 3-15-45 I601 Sound Demod pins 7-18-57 I702 EEPROM pin 8 tuner I501 Main IC pins 25-54 5V 3.3V Remarks FBT supplies 43V to I301 vertical IC FBT supplies 43 V to T401 H- drive for CP785 FBT supplies 12V to I301 vertical IC FBT supplies 33V to the tuner FBT supplies 188V to I901 video amplifier pin 6 b) TV set on stand-by mode * TV set circuit diagram on stand-by mode - 64 - I810 CONDUCTING controlled rectifier 1 D821 I823 3.3V REGULATOR 3 C840 HIGH C841 AROUND 3.3Vdc AROUND 6V dc 16 D825 T801 SM PS TRA N S R810 R713 2 I810 CONTROLLED RECTIFIER SW I T C H I N G CIRCUIT 8 4 D806 - 65 - L801 SW801 POWER SWITCH 4 com M A I N µsupply 1 voltage IC DRAIN I801 MOFSET AND CONTROL IC OCP FB R806 C850 R870 I804 3 1 2 I703 IR RECEIVER 1 I501 C808 3 64 61 56 54 D811 2 OPTO COUPLER KEY IN 7 FRONT M A SK BUTTONS POWER CONDUCTING 63 Q811 LOW MAIN AC VOLTAGE HIGH CONDUCTING R888 Q810 Q809 LOW C888 Fig : Power supply operation in stand - by mode Service manual WP 895/895F, CP885/885F D801...D804 GRAETZ BRIDGE IR IN Service manual WP 895/895F, CP885/885F I810 CONTROLLED RECTIFIER 6V DC HIGH R829 R830 R820 C830 HIGH Q807 Q808 LOW HIGH Q809 POWER LOW Fig : I810 controlled rectifier switching circuit * TV set stand-by mode operations - On stand-by mode, I501 microcontroller pin 1 (power) is set to low. - So, Q809 collector is set to high. - Then, I810 controlled rectifier gate pin is set to high and I810 is conducting. - So, current flows from pin 16 SMPS transformer to the ground via I804 optocoupler and Q810 and Q811 transistors (which are conducting). - In these conditions, I801 delivers pulses on light mode and T801 produces voltages with reduced power. - As I810 is conducting, current flows also from pin 16 SMPS transformer to I823 (5V / 3.3V regulator) for I501 com, IR receiver and front mask buttons supply voltage (then, remote control or front mask buttons can be activated to leave stand-by mode). - 66 - Service Manual WP-895/895F, CP885/885F 6.
