1-3 ATSS sorting method

The TV set sweeps all the TV bands from beginning of VHF to end of UHF. 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 available, 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.

group I, II or III ( e.g. Regional program SW3 in Germany ).

Service manual SC-150

-12-

The sor ting order within group II, III, and IV is based on the channel frequency. The Pro gram with the lo west

frequency is allocated the first rank in its group, and so f orth until the last program of the group which has the

highest fr equency.

If France is selected, the TV controlling softw are f irst swe eps all TV bands with Fr ance system selected

( positive video modulation) and the a second time with Europe system selected ( negative video modulation).

Special case : Switzerland

If Switzerland is selected the TV controlling softw are f irst s weeps all TV bands with Eur ope system selected

(ne gative video modulation) and then a second time with France system selected ( positive video modulation).

Special case : GB

Note for sa tellite recei ver users : Before starting ATSS tur n On your satellite r ecei ver and tune “ SKY NEWS ”.

If GB is selected the TV controlling software seeks for programs only in UHF ( C21 to C70 ).

The sorting order is :

1 - BBC1

2 - BBC2

3 - ITV

4 - CH4

5 - CH5

6 - NEWS

If two or more “ identical” pr ograms ( same name but different code e.g. BBC1 and BBC1 Scotland ) are found

the following pro grams in the list will be shifted up. (1 - BBC1, 2 - BBC1, 3 - BBC2, 4 -ITV, 5 - CH4, 6 - CH5,

7 - NEWS, ..)

If one of the progr am abo ve is not f ound, the associated program number remains empty

( freq.=467.25 Mhz - Skip selected - no name - system=GB).

2 - Safety instruction

WARNING: Only competent service personnel may carry out work involving the testing or repair of this equipment.

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 current. 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.

The Video Front End section takes in the analogue Composite Video and Blanking Signal (CVBS), and from this

extracts the required data, which is then decoded and stored in memory.

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.

- Precise bit-error rate indication

- Automatic switching from NICAM to FM/AM or vice versa

- Improved NICAM synchronisation algorithm

- Improved carrier mute algorithm

- Improved AM-demodulation

- Reduction of necessary controlling

- Less external components

4-2-1- Basic Features of the MSP 341x

4-2-1-1 Demodulator and NICAM Decoder Section

The MSP 341x is designed to simultaneously perform digital demodulation and decoding of NICAM-coded TV stereo

sound, as well as demodulation of FM or AM mono TV sound. Alternatively, two carrier FM systems according to the

German terrestrial specs can be processed with the MSP 341x.

The MSP 341x facilitates profitable multistandard capability, offering the following advantages:

- Automatic Gain Control (AGC) for analogue input: input range: 0.10 - 3 Vpp

- integrated A/D converter for sound-IF input

- all demodulation and filtering is performed on chip and is individually programmable

- easy realisation of all digital NICAM standards (B/G, I, L and D/K)

- FM-demodulation of all terrestrial standards (include identification decoding)

- no external filter hardware is required

- only one crystal clock (18.432 MHz) is necessary

Service manual SC-150

-25-

- high deviation FM-mono mode (max. deviation: approx. ±360 kHz)

4-2-1-2 DSP-Section (Audio Baseband Processing)

- flexible selection of audio sources to be processed

- performance of terrestrial de-emphasise systems (FM, NICAM)

- digitally performed FM-identification decoding and de-matrixing

- digital baseband processing: volume, bass, treble

- simple controlling of volume, bass, treble

4-2-1-3 Analogue Section

- two selectable analogue pairs of audio baseband input (= two SCART inputs) input level: <2 V RMS,

input impedance: >25

- one selectable analogue mono input (i.e. AM sound): Not used in this chassis

- two high-quality A/D converters, S/N-Ratio: >85 dB

- 20 Hz to 20 kHz bandwidth for SCART-to-SCART copy facilities

- loudspeaker: one pair of four-fold oversampled D/A converters. Output level per channel:

max. 1.4 VRMS output resistance: max. 5 . S/N-ratio: >85 dB at maximum volume Max.

noise voltage in mute mode: < 10 V (BW: 20 Hz... 16kHz)

- one pair of four-fold oversampled D/A converters supplying a pair of SCART-outputs.

output level per channel: max. 2 V RMS, output resistance: max. 0.5 , S/N-Ratio: >85 dB (20 Hz... 16 kHz)

4-2-1-4 NICAM plus FM/AM-Mono

According to the British, Scandinavian, Spanish, and French TV-standards, high-quality stereo sound is transmitted

digitally. 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/AM-

mono 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.

The video IF signal (VIF) is fed through a SAW filter to the differential input (Pin 6-7) of the VIF amplifier.

5-2-2 Vision IF Amplifier

This amplifier consists of three AC-coupled amplifier stages. Each differential amplifier is gain controlled by the

automatic gain control circuit (VIF-AGC). The output signal of the VIF amplifier is applied to the FPLL carrier

generation and the video demodulator.

- Channel 2 ( L, D/K, I, B/G) with one pass band for

sound carriers between 32.40 MHz and 33.40 MHz

5-2-3 Tuner-and VIF-AGC

At Pin 8, the VIF-AGC charges/discharges the AGC capacitor to generate a control Voltage for setting the gain of the

VIF amplifier and tuner in order to keep the video output signal at a constant level. 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” an d 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 (0

) and the quadrature signal (90

) of the generated picture carrier.

Service manual SC-150

-46-

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.

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.

Service manual SC-150

-48-

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.

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.

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 synchro-

nously 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 program-

mable 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 9-

bit 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 white-

drive current measurement are carried out during the vertical blanking interval. They always use the small bandwidth

setting.

Service manual SC-150

-50-

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, other-

wise 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.

Service manual SC-150

-51-

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 softwa re 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 program-

mable 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 8-

bit data bus, and a 16-bit address bus.

5-4-3 - Controller I/O pin configuration and function

There exist different kinds of ports. The universal ports serv

e 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

pin name description

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

Service manual SC-150

-54-

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,

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 hyster-

esis 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. Roma-

nian national font options will be selected.

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.

Service manual SC-150

-57-

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 r

ate 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 contr

olling 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 dif

ferent.

In “forced mono “ mode ( Red OSD in status Display Window),

the controlling software configures the MSP341xD to

demodulate 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 TDA8946J is a stereo BTL audio amplifier capable of delivering 2 x 15 W output power to

an 8 W load at THD = 10%, using a 18 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 8946J 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

Service manual SC-150

-58-

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 < V

MODE

< (Vcc-1.5 V).

Operating : In this mode the amplifier is operating normally. The operating mode is activated at V

MODE

< 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 V

flb

. 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 V

flb

optimum for the flyback voltage. Using this method, very high efficiency is achieved. The supply voltage

flb

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.

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 : V

The start-up circuit is used to start and stop the operation of the control IC, by detecting a voltage appearing at V

pin (pin 4).

When the power switch is pushed on, V

increases slowly. During this time, C806 is charged through R802.

As soon as V

reaches 16V, the STR-F6654 control circuit starts operating. Then, V

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, V

starts dropping. However, as this winding voltage reaches the set value before V

voltage drops to the shutdown

voltage (at 11V), the control circuit continues operating (see below V

voltage at start-up). R805 resistor prevents that

pin voltage varies according to the secondary side output current.

5-9-2-2 STR-F6654 oscillating operation

Service manual SC-150

-62-

When the MOSFET is ON, the STR-F6654 internal capacitor C1 is charged at the constant voltage 6.5V.

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 V

TH1

= 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.

Overcurrent protection is performed pulse by pulse detecting at STR-F6654 pin 1 (OCP) the peak of the MOSFET

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...

D804 diodes). Then, T801 SMPS transformer starts operating and supplies DC voltage to I823 (5V regulator).

- This regulator provides 5V / 3.3V DC voltage to I501 microcontroller power supply pins (pin 3 / pin 54) and to the

reset pulse circuit which provides reset pulse to I501 microcontroller reset pin (pin 58).

- Then, the microcontroller starts its initialisation. Its power pin (pin 1) is set to high which allows delivery of power

supply voltages (123V, 8V, 5V...). At this step, all IC’s start working but no picture appears on screen: I501 IC

doesn’t provide horizontal drive voltage.

- Then, the microcontroller consults I702 EEPROM via I2C bus to know the last TV set mode (normal run mode or

stand-by mode ) before switching off.

. If the TV set was on normal run mode before switching off, the microcontroller delivers horizontal drive voltage at pin

24 and picture appears on screen.

. If the TV set was on stand-by mode before switching off, the microcontroller switches TV set to stand-by mode,

Depending on remote control commands, I501 microcontroller part pin 1 (power) is set to :

- high for normal run mode

- low for stand-by mode

a) TV on normal run mode

* I501 microcontroller part pin 1 (power) effect

I501 microcontroller part pin 1 (power) is connected to the following circuit :

Service manual SC-150

-65-

On normal run mode, I501 microcontroller pin 1 (power) is set to high

So, I810 controlled rectifier is not conducting

- Q809 is conducting. 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

Service manual SC-150

-66-

* 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.

* 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).
