2. Safety Instructions, Warnings, and Notes
•

Index of this chapter:
2.1 Safety Instructions
2.2 Warnings
2.3 Notes

2.1

Safety regulations require the following during a repair:
• Connect the set to the Mains/AC Power via an isolation
transformer (> 800 VA).
• Replace safety components, indicated by the symbol h,
only by components identical to the original ones. Any
other component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay in particular attention to
the following points:
• Route the wire trees correctly and fix them with the
mounted cable clamps.
• Check the insulation of the Mains/AC Power lead for
external damage.
• Check the strain relief of the Mains/AC Power cord for
proper function.
• Check the electrical DC resistance between the Mains/AC
Power plug and the secondary side (only for sets that have
a Mains/AC Power isolated power supply):
1. Unplug the Mains/AC Power cord and connect a wire
between the two pins of the Mains/AC Power plug.
2. Set the Mains/AC Power switch to the “on” position
(keep the Mains/AC Power cord unplugged!).
3. Measure the resistance value between the pins of the
Mains/AC Power plug and the metal shielding of the
tuner or the aerial connection on the set. The reading
should be between 4.5 MΩ and 12 MΩ.
4. Switch “off” the set, and remove the wire between the
two pins of the Mains/AC Power plug.
• Check the cabinet for defects, to prevent touching of any
inner parts by the customer.

Safety Instructions

2.3.2

•
•
•
•
•

•
•
•

All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD w). Careless handling
during repair can reduce life drastically. Make sure that,
during repair, you are connected with the same potential as
the mass of the set by a wristband with resistance. Keep
components and tools also at this same potential.
Be careful during measurements in the high voltage
section.
Never replace modules or other components while the unit
is switched “on”.
When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a
circuit becoming unstable.

2.3

Notes

2.3.1

General
•

Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the tested area of circuitry. The voltages and waveforms
shown in the diagrams are indicative. Measure them in the
Service Default Mode (see chapter 5) with a colour bar
signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated
otherwise) and picture carrier at 475.25 MHz for PAL, or
61.25 MHz for NTSC (channel 3).

All resistor values are in ohms, and the value multiplier is
often used to indicate the decimal point location (e.g. 2K2
indicates 2.2 kΩ).
Resistor values with no multiplier may be indicated with
either an “E” or an “R” (e.g. 220E or 220R indicates 220 Ω).
All capacitor values are given in micro-farads (μ = × 10-6),
nano-farads (n = × 10-9), or pico-farads (p = × 10-12).
Capacitor values may also use the value multiplier as the
decimal point indication (e.g. 2p2 indicates 2.2 pF).
An “asterisk” (*) indicates component usage varies. Refer
to the diversity tables for the correct values.
The correct component values are listed in the Spare Parts
List. Therefore, always check this list when there is any
doubt.

2.3.3

Where necessary, measure the waveforms and voltages
with (D) and without (E) aerial signal. Measure the
voltages in the power supply section both in normal
operation (G) and in stand-by (F). These values are
indicated by means of the appropriate symbols.

2.3.4

Lead-free Soldering
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
• Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106. If lead-free solder paste is required,
please contact the manufacturer of your soldering
equipment. In general, use of solder paste within
workshops should be avoided because paste is not easy to
store and to handle.
• Use only adequate solder tools applicable for lead-free
soldering tin. The solder tool must be able:
– To reach a solder-tip temperature of at least 400°C.
– To stabilize the adjusted temperature at the solder-tip.
– To exchange solder-tips for different applications.
• Adjust your solder tool so that a temperature of around
360°C - 380°C is reached and stabilized at the solder joint.
Heating time of the solder-joint should not exceed ~ 4 sec.
Avoid temperatures above 400°C, otherwise wear-out of
tips will increase drastically and flux-fluid will be destroyed.
To avoid wear-out of tips, switch “off” unused equipment or
reduce heat.
• Mix of lead-free soldering tin/parts with leaded soldering
tin/parts is possible but PHILIPS recommends strongly to

EN 6

example below it is 2006 week 17). The 6 last digits contain the
serial number.

avoid mixed regimes. If this cannot be avoided, carefully
clear the solder-joint from old tin and re-solder with new tin.
2.3.5

Alternative BOM identification

MODEL

It should be noted that on the European Service website,
“Alternative BOM” is referred to as “Design variant”.

PROD.NO: AG 1A0617 000001

The third digit in the serial number (example:
AG2B0335000001) indicates the number of the alternative
B.O.M. (Bill Of Materials) that has been used for producing the
specific TV set. In general, it is possible that the same TV
model on the market is produced with e.g. two different types
of displays, coming from two different suppliers. This will then
result in sets which have the same CTN (Commercial Type
Number; e.g. 28PW9515/12) but which have a different B.O.M.
number.
By looking at the third digit of the serial number, one can
identify which B.O.M. is used for the TV set he is working with.
If the third digit of the serial number contains the number “1”
(example: AG1B033500001), then the TV set has been
manufactured according to B.O.M. number 1. If the third digit is
a “2” (example: AG2B0335000001), then the set has been
produced according to B.O.M. no. 2. This is important for
ordering the correct spare parts!
For the third digit, the numbers 1...9 and the characters A...Z
can be used, so in total: 9 plus 26= 35 different B.O.M.s can be
indicated by the third digit of the serial number.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 1 and 2 refer to the production center (e.g.
AG is Bruges), digit 3 refers to the B.O.M. code, digit 4 refers
to the Service version change code, digits 5 and 6 refer to the
production year, and digits 7 and 8 refer to production week (in

Board Level Repair (BLR) or Component Level Repair
(CLR)
If a board is defective, consult your repair procedure to decide
if the board has to be exchanged or if it should be repaired on
component level.
If your repair procedure says the board should be exchanged
completely, do not solder on the defective board. Otherwise, it
cannot be returned to the O.E.M. supplier for back charging!

2.3.7

Practical Service Precautions
•

•

It makes sense to avoid exposure to electrical shock.
While some sources are expected to have a possible
dangerous impact, others of quite high potential are of
limited current and are sometimes held in less regard.
Always respect voltages. While some may not be
dangerous in themselves, they can cause unexpected
reactions that are best avoided. Before reaching into a
powered TV set, it is best to test the high voltage insulation.
It is easy to do, and is a good service precaution.

Service Positions

The foam bars (order code 3122 785 90580 for two pieces) can
be used for all types and sizes of Flat TVs. See figure “Foam
bars” for details. Sets with a display of 42" and larger, require
four foam bars [1]. Ensure that the foam bars are always
supporting the cabinet and never only the display.
Caution: Failure to follow these guidelines can seriously
damage the display!
By laying the TV face down on the (ESD protective) foam bars,
a stable situation is created to perform measurements and
alignments. By placing a mirror under the TV, you can monitor
the screen.

For easy servicing of this set, there are a few possibilities
created:
• The buffers from the packaging (see figure “Rear cover”).
• Foam bars (created for Service).

Service Modes, Error Codes, and Fault Finding

5. Service Modes, Error Codes, and Fault Finding

5.1

Test Points
In the chassis schematics and layout overviews, the test points
(Fxxx) are mentioned. In the schematics, test points are
indicated with a rectangular box around “Fxxx” or “Ixxx”, in the
layout overviews with a “half-moon” sign.
As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope. Several key ICs are
capable of generating test patterns, which can be controlled via
ComPair. In this way it is possible to determine which part is
defective.
Perform measurements under the following conditions:
• Service Default Mode.
• Video: Colour bar signal.
• Audio: 3 kHz left, 1 kHz right.

5.2

Service Modes
The Service Mode feature is split into four parts:
• Service Default Mode (SDM).
• Service Alignment Mode (SAM).
• Customer Service Mode (CSM).
• Digital Customer Service Mode (DCSM).
• Computer Aided Repair Mode (ComPair).
SDM and SAM offer features, which can be used by the Service
engineer to repair/align a TV set. Some features are:
• A pre-defined situation to ensure measurements can be
made under uniform conditions (SDM).
• Activates the blinking LED procedure for error identification
when no picture is available (SDM).
• The possibility to overrule software protections when SDM
was entered via the Service pins.
• Make alignments (e.g. white tone), (de)select options,
enter options codes, reset the error buffer (SAM).
• Display information (“SDM” or “SAM” indication in upper
right corner of screen, error buffer, software version,
operating hours, options and option codes, sub menus).
The CSM is a Service Mode that can be enabled by the
consumer. The CSM displays diagnosis information, which the
customer can forward to the dealer or call centre. In CSM
mode, “CSM”, is displayed in the top right corner of the screen.
The information provided in CSM and the purpose of CSM is to:
• Increase the home repair hit rate.
• Decrease the number of nuisance calls.
• Solved customers' problem without home visit.
ComPair Mode is used for communication between a computer
and a TV on I2C /UART level and can be used by a Service
engineer to quickly diagnose the TV set by reading out error
codes, read and write in NVMs, communicate with ICs and the
uP (PWM, registers, etc.), and by making use of a fault finding
database. It will also be possible to up and download the
software of the TV set via I2C with help of ComPair. To do this,
ComPair has to be connected to the TV set via the ComPair
connector, which will be accessible through the rear of the set
(without removing the rear cover).

5.2.1

General
Some items are applicable to all Service Modes or are general.
These are listed below.
Life Timer
During the life time cycle of the TV set, a timer is kept. It counts
the normal operation hours (not the Stand-by hours). The
actual value of the timer is displayed in SDM and CSM in a
decimal value. Every two soft-resets increase the hour by +1.
Software Identification, Version, and Cluster
The software ID, version, and cluster will be shown in the main
menu display of SDM, SAM, and CSM.
The screen will show: “AAAABCD X.YY”, where:
• AAAA is the chassis name: LC81.
• B is the region indication: E= Europe, A= AP/China, U=
NAFTA, L= LATAM.
• C is the display indication: L= LCD, P= Plasma.
• D is the language/feature indication: 1= standard, H=
1080p full HD.
• X is the main version number: this is updated with a major
change of specification (incompatible with the previous
software version). Numbering will go from 1 - 9 and A - Z.
– If the main version number changes, the new version
number is written in the NVM.
– If the main version number changes, the default
settings are loaded.
• YY is the sub version number: this is updated with a minor
change (backwards compatible with the previous versions)
Numbering will go from 00 - 99.
– If the sub version number changes, the new version
number is written in the NVM.
– If the NVM is fresh, the software identification, version,
and cluster will be written to NVM.
Display Option Code Selection
When after an SSB or display exchange, the display option
code is not set properly, it will result in a TV with “no display”.
Therefore, it is required to set this display option code after
such a repair.
To do so, press the following key sequence on a standard RC
transmitter: “062598” directly followed by MENU and “xxx”,
where “xxx” is a 3 digit decimal value of the panel type: see
column “Display code” in table “Option code overview” (ch. 8),
or see sticker on the side/bottom of the cabinet. When the value
is accepted and stored in NVM, the set will switch to Stand-by,
to indicate that the process has been completed.

During this algorithm, the NVM-content must be filtered,
because several items in the NVM are TV-related and not SSBrelated (e.g. Model and Prod. S/N). Therefore, “Model” and
“Prod. S/N” data is changed into “See Type Plate”.
In case a call centre or consumer reads “See Type Plate” in
CSM mode, he needs to look to the side/bottom sticker to
identify the set, for further actions.

Purpose
The Customer Service Mode shows error codes and
information on the TV’s operation settings. A call centre can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set. This helps them to diagnose
problems and failures in the TV before making a service call.
The CSM is a read-only mode; therefore, modifications are not
possible in this mode.
Specifications
• Ignore “Service unfriendly modes”.
• Line number for every line (to make CSM language
independent).
• Set the screen mode to full screen (all contents on screen
are viewable).
• After leaving the Customer Service Mode, the original
settings are restored.
• Possibility to use “CH+” or “CH-” for channel surfing, or
enter the specific channel number on the RC.
How to Activate
To activate CSM, press the following key sequence on the
remote control transmitter: “123654” (do not allow the display
to time out between entries while keying the sequence).

Introduction

Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips
Consumer Electronics products. and offers the following:
1. ComPair helps you to quickly get an understanding on how
to repair the chassis in a short and effective way.
2. ComPair allows very detailed diagnostics and is therefore
capable of accurately indicating problem areas. You do not
have to know anything about I2C or UART commands
yourself, because ComPair takes care of this.
3. ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the uP
is working) and all repair information is directly available.
4. ComPair features TV software up possibilities.

Error codes are required to indicate failures in the TV set. In
principle a unique error code is available for every:
• Activated protection.
• Failing I2C device.
• General I2C error.
• SDRAM failure.
The last errors, stored in the NVM, are shown in the Service
menu’s. This is called the error buffer.
The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, it is displayed at the left side and all other errors shift one
position to the right.
An error will be added to the buffer if this error differs from any
error in the buffer. The last found error is displayed on the left.
An error with a designated error code may never lead to a
deadlock situation. This means that it must always be
diagnosable (e.g. error buffer via OSD or blinking LED
procedure, ComPair to read from the NVM).
In case a failure identified by an error code automatically
results in other error codes (cause and effect), only the error
code of the MAIN failure is displayed.

Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The (new) ComPair II interface box is connected to the PC via
an USB cable. For the TV chassis, the ComPair interface box
and the TV communicate via a bi-directional cable via the
service connector(s).
How to Connect
This is described in the ComPair chassis fault finding database.

Example: In case of a failure of the I2C bus (CAUSE), the error
code for a “General I2C failure” and “Protection errors” is
displayed. The error codes for the single devices (EFFECT) is
not displayed. All error codes are stored in the same error
buffer (TV’s NVM) except when the NVM itself is defective.

You can read the error buffer in 3 ways:
• On screen via the SAM/SDM/CSM (if you have a picture).
Example:
– ERROR: 0 0 0 0 0: No errors detected
– ERROR: 6 0 0 0 0: Error code 6 is the last and only
detected error
– ERROR: 9 6 0 0 0: Error code 6 was detected first and
error code 9 is the last detected (newest) error
• Via the blinking LED procedure (when you have no
picture). See “The Blinking LED Procedure”.
• Via ComPair.

Caution: It is compulsory to connect the TV to the PC as
shown in the picture above (with the ComPair interface in
between), as the ComPair interface acts as a level shifter. If
one connects the TV directly to the PC (via UART), ICs will be
blown!
How to Order
ComPair II order codes:
• ComPair II interface: 3122 785 91020.
• The latest ComPair software can be found on the Philips
Service website.
• ComPair I2C interface cable: 9965 100 07325 (to be used
for upgrading the Main software).
Note: If you encounter any problems, contact your local
support desk.

Support of the LVDS Tool has been discontinued.

Error Codes
In case of non-intermittent faults, write down the errors present
in the error buffer and clear the error buffer before you begin
the repair. This ensures that old error codes are no longer
present.
If possible, check the entire contents of the error buffer. In
some situations, an error code is only the result of another error
and not the actual cause of the problem (for example, a fault in
the protection detection circuitry can also lead to a protection).

Errors can also be displayed by the blinking LED procedure.
The method is to repeatedly let the front LED pulse with as
many pulses as the error code number, followed by a period of
1.5 seconds in which the LED is “off”. Then this sequence is
repeated.
Example (1): error code 4 will result in four times the sequence
LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After
this sequence, the LED will be “off” for 1.5 seconds. Any RC5
command terminates the sequence. Error code LED blinking is
in red colour.

To erase the error buffer, the RC command “MUTE” “062599
“OK” can be used.

5.6

How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
• By using the CLEAR command in the SAM menu:
– To enter SAM, press the following key sequence on the
remote control transmitter: “062596” directly followed
by the OSD/STATUS/INFO/i+ button (do not allow the
display to time out between entries while keying the
sequence).
– Make sure the menu item CLEAR is selected. Use the
MENU UP/DOWN buttons, if necessary.
– Press the MENU RIGHT button to clear the error
buffer. The text on the right side of the “CLEAR” line will
change from “CLEAR?” to “CLEARED”
• If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.
Note: If you exit SAM by disconnecting the mains from the
television set, the error buffer is not reset.

Displaying the Entire Error Buffer
Additionally, the entire error buffer is displayed when Service
Mode “SDM” is entered. In case the TV set is in protection or
Stand-by: The blinking LED procedure sequence (as in SDMmode in normal operation) must be triggered by the following
RC sequence: “MUTE” “062500” “OK”.
In order to avoid confusion with RC5 signal reception blinking,
this blinking procedure is terminated when a RC5 command is
received.

external) communicating with
FPGA (only applicable to
AmbiLight sets)

Notes
1. Some of the error codes reported are depending on the
option code configurations.
2. This error means: no I2C device is responding to the
particular I2C bus. Possible causes: SCL/SDA shorted to
GND, SCL shorted to SDA, or SCL/SDA open (at uP pin).
The internal bus of the Trident platform should not cause
the entire system to halt as such an error can be reported.
5.4.4

EN 21

The software is capable of identifying different kinds of errors.
Because it is possible that more than one error can occur over
time, an error buffer is available, which is capable of storing the
last five errors that occurred. This is useful if the OSD is not
working properly.

7C04

(7M07)

Example (2): the content of the error buffer is “1 2 9 6 0 0”
After entering SDM, the following occurs:
• 1 long blink of 5 seconds to start the sequence,
• 12 short blinks followed by a pause of 1.5 seconds,
• 9 short blinks followed by a pause of 1.5 seconds,
• 6 short blinks followed by a pause of 1.5 seconds,
• 1 long blink of 1.5 seconds to finish the sequence,
• The sequence starts again with 12 short blinks.

Introduction

The TV will not start-up
due to critical data not
available from the NVM,
but the LED will blink the
error code.

When Trident IC is
defective, error 10 and 14
might also be reported.
Trident communicates via
parallel bus, not via the
I2C bus. The I2C bus of

Service Modes, Error Codes, and Fault Finding

Fault Finding and Repair Tips

Alternative method (1):
1. Go to SAM.
2. Select NVM Editor.
3. Select ADR (address) to 1 (dec).
4. Change the VAL (value) to 170 (dec).
5. Store the value.
6. Do a hard reset to make sure new default values took
place.

Notes:
• It is assumed that the components are mounted correctly
with correct values and no bad solder joints.
• Before any fault finding actions, check if the correct options
are set.
5.7.1

NVM Editor

Alternative method (2):
It is also possible to upload the default values to the NVM with
ComPair in case the SW is changed, the NVM is replaced with
a new (empty) one, or when the NVM content is corrupted.
After replacing an EEPROM (or with a defective/no EEPROM),
default settings should be used to enable the set to start-up and
allow the Service Default Mode and Service Alignment Mode to
be accessed.

In some cases, it can be convenient if one directly can change
the NVM contents. This can be done with the “NVM Editor” in
SAM mode. With this option, single bytes can be changed.
Caution:
• Do not change the NVM settings without
understanding the function of each setting, because
incorrect NVM settings may seriously hamper the
correct functioning of the TV set!
• Always write down the existing NVM settings, before
changing the settings. This will enable you to return to the
original settings, if the new settings turn out to be incorrect.

5.7.2

Load Default NVM Values
It is possible to download default values automatically into the
NVM in case a blank NVM is placed or when the NVM first 20
address contents are “FF”. After the default values are
downloaded, it is possible to start-up and to start aligning the
TV set. To initiate a forced default download the following
action has to be performed:
1. Switch “off” the TV set with the mains cord disconnected
from the wall outlet (it does not matter if this is from
“Stand-by” or “Off” situation).
2. Short-circuit the SDM jumpers on the SSB (keep short
circuited).
3. Press “P+” or “CH+” on the local keyboard (and keep it
pressed).
4. Reconnect the mains supply to the wall outlet.
5. Release the “P+” or “CH+” when the set is “on” or blue LED
is blinking.
When the downloading has completed successfully, the set
should be into Stand-by, i.e. red LED on.

Personal Notes:

Introduction
SRP (Service Reference Protocol) is a software tool that creates a list with all references to signal lines. The list contains
references to the signals within all schematics of a PWB. It replaces the text references currently printed next to the signal
names in the schematics. These printed references are created manually and are therefore not guaranteed to be 100%
correct. In addition, in the current crowded schematics there is often none or very little place for these references.
Some of the PWB schematics will use SRP while others will still use the manual references. Either there will be an SRP
reference list for a schematic, or there will be printed references in the schematic.

1.2.

Non-SRP Schematics
There are several different signals available in a schematic:

1.2.1.

Power Supply Lines
All power supply lines are available in the supply line overview (see chapter 6). In the schematics (see chapter 7) is not
indicated where supplies are coming from or going to.
It is however indicated if a supply is incoming (created elsewhere), or outgoing (created or adapted in the current schematic).
+5V

Outgoing
1.2.2.

+5V

Incoming

Normal Signals
For normal signals, a schematic reference (e.g. B14b) is placed next to the signals.
B14b

1.2.3.

signal_name

Grounds
For normal and special grounds (e.g. GNDHOT or GND3V3 etc.), nothing is indicated.

1.3.

SRP Schematics
SRP is a tool, which automatically creates a list with signal references, indicating on which schematic the signals are used.
A reference is created for all signals indicated with an SRP symbol, these symbols are:
+5V

name

name

+5V

Power supply line.

name

Stand alone signal or switching line (used as less as possible).
name

Signal line into a wire tree.
name

name

Switching line into a wire tree.
name

Bi-directional line (e.g. SDA) into a wire tree.
name

Signal line into a wire tree, its direction depends on the circuit (e.g. ingoing for PDP, outgoing for LCD sets).
Remarks:
•
When there is a black dot on the "signal direction arrow" it is an SRP symbol, so there will be a reference to the signal
name in the SRP list.
•
All references to normal grounds (Ground symbols without additional text) are not listed in the reference list, this to keep
it concise.
•
Signals that are not used in multiple schematics, but only once or several times in the same schematic, are included
in the SRP reference list, but only with one reference.
Additional Tip:
When using the PDF service manual file, you can very easily search for signal names and follow the signal over all the
schematics. In Adobe PDF reader:
•
Select the signal name you want to search for, with the "Select text" tool.
•
Copy and paste the signal name in the "Search PDF" tool.
•
Search for all occurrences of the signal name.
•
Now you can quickly jump between the different occurrences and follow the signal over all schematics. It is advised to
"zoom in" to e.g. 150% to see clearly, which text is selected. Then you can zoom out, to get an overview of the complete
schematic.
PS. It is recommended to use at least Adobe PDF (reader) version 6.x, due to better search possibilities in this version.

8.1 General Alignment Conditions
8.2 Hardware Alignments
8.3 Software Alignments
8.4 Option Settings

Purpose: To keep the tuner output signal constant as the input
signal amplitude varies.
The LC8.1A LA chassis comes with the UV1316E analogue
tuner. No alignment is necessary, as the AGC alignment is
done automatically (standard value: “15”). However in case of
problems use the following method (use multimeter and RF
generator):
• Apply a vision IF carrier of 38.9 MHz (105 dBuV = 178
mVrms) to test point F101 (input via 50 ohm coaxial cable
terminated with an RC network of series 10nF with 120
ohm to ground).
• Measure voltage on pin 1 of the tuner (test point F116).
• Adjust AGC (via SAM menu: TUNER -> AGC), until voltage
on pin 1 is 3.3 +0.5/-1.0 V.
• Store settings and exit SAM.

Note: Figures below can deviate slightly from the actual
situation, due to the different set executions.
General: The Service Default Mode (SDM) and Service
Alignment Mode (SAM) are described in chapter 5. Menu
navigation is done with the CURSOR UP, DOWN, LEFT or
RIGHT keys of the remote control transmitter.

8.1

General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
• Power supply voltage (depends on region):
– AP-NTSC: 120 VAC or 230 VAC / 50 Hz (± 10%).
– AP-PAL-multi: 120 - 230 VAC / 50 Hz (± 10%).
– EU: 230 VAC / 50 Hz (± 10%).
– LATAM-NTSC: 120 - 230 VAC / 50 Hz (± 10%).
– US: 120 VAC / 60 Hz (± 10%).
• Connect the set to the mains via an isolation transformer
with low internal resistance.
• Allow the set to warm up for approximately 15 minutes.
• Measure voltages and waveforms in relation to correct
ground (e.g. measure audio signals in relation to
AUDIO_GND).
Caution: It is not allowed to use heatsinks as ground.
• Test probe: Ri > 10 Mohm, Ci < 20 pF.
• Use an isolated trimmer/screwdriver to perform
alignments.

8.2

Hardware Alignments
There are no hardware alignments foreseen for this chassis,
but below find an overview of the most important DC voltages
on the SSB. These can be used for checking proper functioning
of the DC/DC converters.

RGB Alignment
Before alignment, choose “TV MENU” -> “Picture” and set:
• “Brightness” to “50”.
• “Colour” to “50”.
• “Contrast” to “100”.
White Tone Alignment:
• Activate SAM.
• Select “RGB Align.” -> “White Tone” and choose a colour
temperature.
• Use a 100% white screen as input signal and set the
following values:
– All “White point” values initial to “256”.
– All “BlackL Offset” values to “0”.
In case you have a colour analyser:
• Measure with a calibrated (phosphor- independent) colour
analyser (e.g. Minolta CA-210) in the centre of the screen.
Consequently, the measurement needs to be done in a
dark environment.
• Adjust the correct x,y coordinates (while holding one of the
White point registers R, G or B on “256”) by means of
decreasing the value of one or two other white points to the
correct x,y coordinates (see table “White D alignment
values”). Tolerance: dx: ± 0.004, dy: ± 0.004.
• Repeat this step for the other colour Temperatures that
need to be aligned.
• When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.

Software Alignments
With the software alignments of the Service Alignment Mode
(SAM) the Tuner and RGB settings can be aligned.
To store the data: Use the RC button “Menu” to switch to the
main menu and next, switch to “Stand-by” mode.

If you do not have a colour analyser, you can use the default
values. This is the next best solution. The default values are
average values coming from production (statistics).
• Set the RED, GREEN and BLUE default values per
temperature according to the values in the “Tint settings”
table.
• When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.

Introduction
The microprocessor communicates with a large number of I2C
ICs in the set. To ensure good communication and to make
digital diagnosis possible, the microprocessor has to know
which ICs to address. The presence/absence of these specific
ICs (or functions) is made known by the option codes.

Black Level Offset Alignment
• Activate SAM.
• Select “RGB Align.” -> “BlackL Offset” and choose a colour.
• Set all “BlackL Offset” values to “0”.
• When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.
Note: For models with “Pixel Plus”, the “Black Offset” (black
level offset) should NOT be changed in SAM. These offset
values of RGB should be set to “0”, and should NOT be
adjusted. Any adjustment of these values will affect the low
light white balance.
ADC YPbPr Gray Scale Alignment
When the grey scale is not correct, use this alignment:
• Activate SAM.
• Select “NVM Editor”.
• Enter address “26(dec)” (ADR).
• Set value (VAL) to “197(dec) ± 25”.
• Store (STORE) the value.

Notes:
• After changing the option(s), save them with the STORE
command.
• The new option setting becomes active after the TV is
switched “off” and “on” again with the mains switch (the
EAROM is then read again).
8.4.2

How To Set Option Codes
When the NVM is replaced, all options will require resetting. To
be certain that the factory settings are reproduced exactly, you
must set all option numbers. You can find the correct option
numbers in table “Option Codes OP1...OP7” below.
How to Change Options Codes
An option code (or “option byte”) represents eight different
options (bits). When you change these numbers directly, you
can set all options very quickly. All options are controlled via
seven option bytes (OP1... OP7).
Activate SAM and select “Options”. Now you can select the
option byte (OP1 to OP7) with the CURSOR UP/ DOWN keys,
and enter the new 3 digit (decimal) value. For the correct
factory default settings, see the next table “Option codes
OP1...OP7“. For more detailed information, see the second
table “Option codes at bit level“. If an option is set (value “1”), it
represents a certain decimal value.
When all the correct options (bits) are set, the sum of the
decimal values of each Option Byte (OP) will give the option
code.

LCD Power Supply
The Power Supply Unit (PSU) in this chassis is a buy-in and is
a black-box for Service. When defective, a new panel must be
ordered and the defective panel must be returned for repair,
unless the main fuse of the unit is broken. Always replace the
fuse with one with the correct specifications! This part is
commonly available in the regular market.

Front-End
This chassis uses the UV1316E analogue tuner.

Figure 9-5 Tuner IF diagram
While receiving analogue signals, the signal coming from the
tuner is fed to the IF demodulator (through the SAW filters) and
then passed to the Trident Video Processor.

DC/DC converters
On-board DC-DC converters convert the +12 V coming from
the PSU and deliver the following voltages:
• +5 V (+5Vtuner)
• +VTUN
• +5 V (+5V_SW)
• +3.3 V (+3V3_SW)
• +2.5 V (+2V5_SW)
• +1.8 V (+1V8_SW)
• +1.2 V (+1V2_SW)
• +8 V (+8V)

9.4.1

Video IF Amplifier
The IF-filter is integrated in a SAW (Surface Acoustic Wave)
filter. One for filtering IF-video (item 1102) and one for IF-audio
(item 1103). The video IF filter can be switched to another
standard, what makes it suitable for applications in multistandard platforms.
Switching is done by the microcontroller via SAW_SW. In table
“SAW filter switching” is explained how to address the different
system standards.

The following diagram shows the power supply architecture of
the SSB:

The audio decoding is done entirely via the Multistandard
Sound Processor (MSP) 4450P (item 7411).
This processor covers the processing of both analogue and
(NICAM) digital input signals by processing the (analogue) IF
signal-in to processed (analogue) AF-out (baseband audio). An
internal 40 ms (stereo) audio delay line (LIP SYNC) is foreseen
and therefore no external delay line is necessary.

Figure 9-7 Block diagram audio processing - AP application
In AP applications, the MSP features:
• Sound IF input for signals coming from the analogue
front-end
• Three I2S-inputs for signals (“DATA”, “CLK” and “WS”)
coming from the HDMI receiver
• Five analogue inputs
• Loudspeaker output path
• Headphone output path.
In case of reception from HDMI sources, digital audio signals
are directly fed to the MSP via the I2S_DA_IN3, I2S_WS3 and
I2S_CL3 lines. This ensures a “true digital path”.
The microprocessor (item 7311) controls the audio part with the
following control lines:
• MUTEn: used to mute the Class D amplifiers
• ANTI_PLOP: used to detect any DC failure in the Class D
amplifiers
• DC_PROT: used to detect any DC failure in the Class D
amplifiers.

Audio Amplifier
The audio amplifier is an integrated class-D amplifier
(TDA8932T, item 7A01). It combines a good performance with
a high efficiency, resulting in a big reduction in heat generation.

Introduction
Note: Text below is an excerpt from the ”HDMI Specification”
that is issued by the HDMI founders (see http://www.hdmi.org).
The High-Definition Multimedia Interface is developed for
transmitting digital signals from audiovisual sources to
television sets, projectors and other video displays.
HDMI can carry high quality multi-channel audio data and can
carry all standard and high-definition consumer electronics
video formats. Content protection technology is available.
HDMI can also carry control and status information in both
directions.

-V
G_16860_080.eps
020207

Figure 9-8 Principle Class-D Amplifier
The Class D amplifier works by varying the duty cycle of a
Pulse Width Modulated (PWM) signal.
By comparing the input voltage to a triangle wave, the amplifier
increases duty cycle to increase output voltage, and decreases
duty cycle to decrease output voltage.
The output transistors of a Class D amplifier switch from 'full off'
to 'full on' (saturated) and then back again, spending very little
time in the linear region in between. Therefore, very little power
is lost to heat. If the transistors have a low 'on' resistance
(RDS(ON)), little voltage is dropped across them, further
reducing losses.
A Low Pass Filter at the output passes only the average of the
output wave, which is an amplified version of the input signal.
In order to keep the distortion low, negative feedback is
applied.
The advantage of Class D is increased efficiency (= less heat
dissipation). Class D amplifiers can drive the same output
power as a Class AB amplifier using less supply current.
The disadvantage is the large output filter. The main reason
for this filter is that the switching waveform results in maximum
current flow. This causes more loss in the load, which causes
lower efficiency. An LC filter with a cut-off frequency less than
the Class D switching frequency, allows the switching current
to flow through the filter instead of the load, thus reducing the
overall loss and increasing the efficiency.
DC-protection
A DC-detection circuit is foreseen to protect the speakers. It is
built around three transistors (items 7A05 to 7A07) and
generates a protection signal (DC_PROT) to the
microprocessor in case of a DC failure in the Class D
amplifiers.

HDMI is backward compatible with DVI (1.0). Compared with
DVI, HDMI offers extra:
• YUV 4:4:4 (3 × 8-bit) or 4:2:2 (up to 2 × 12-bit), where DVI
offers only RGB 4:4:4 (3 × 8 bit).
• Digital audio in CD quality (16-bit, 32/44.1/48 kHz), higher
quality available (8 channels, 192 kHz).
• Remote control via CEC bus (Consumer Electronics
Control): allows user to control all HDMI devices with the
TV's remote control and menus.
• Smaller connector (SCART successor).
• Less cables: e.g. from 10 audio/9 video cables to 3 HDMI
cables.
9.7.2

Implementation
The IC used is the Sil 9025 (Silicon Image) third generation
HDMI receiver (item 7N17 on the SSB) with following features:
• Dual HDMI input connector.
• Two EEPROMS to support EDID.
• HDMI audio.
• I2S output to DACs which operating freq. of 32 to 192 kHz.
• Integrated HDCP decryption engine.
• Built-in pre-programmed HDCP keys for copy protection.
• Colour space conversion RGB to YCbCr.
• “Hot Plug Reset” signal.

HDMI connectors 1 and 2 are connected to resp. ports 1 and 2
of the HDMI receiver. The ports cannot be activated at the
same moment. Switching is controlled by software.
“Hot Plug Reset” and “DDC Reset” are controlled by the
microprocessor.
The HDMI receiver will convert all RGB or YCbCr 4:2:2 signals
to 24-bit YCbCr 4:4:4. When it receives a YCbCr 4:4:4 signal it
will just pass the signal directly to the Trident Video Processor.
