3.4 Abbreviation List
3.1 Safety Instructions
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 M and 12 M.
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.
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.
3.3.2 Schematic Notes
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 k).
Resistor values with no multiplier may be indicated with either an “E” or an “R” (e.g. 220E or 220R indicates 220 ).
All capacitor values are given in micro-farads (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 on the Philips Spare Parts Web Portal.
3.3.3 Spare Parts
For the latest spare part overview, consult your Philips Spare Part web portal.

Precautions, Notes, and Abbreviation List
EN 7L11M1.1L LA 3.
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 centre (e.g. SN is Lysomice, RJ is Kobierzyce), 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 example below it is 2010 week 10 / 2010 week 17). The 6 last digits contain the serial number.

4.2 Service Positions
For easy servicing of a TV set, the set should be put face down on a soft flat surface, foam buffers or other specific workshop tools. Ensure that a stable situation is created to perform
measurements and alignments. When using foam bars take care that these always support the cabinet and never only the display. Caution: Failure to follow these guidelines can seriously damage the display! Ensure that ESD safe measures are taken.

5.1 Test Points
In the chassis schematics and layout overviews, the test points are mentioned. In the schematics and layouts, test points are indicated with “Fxxx” or “Ixxx”. 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: Color 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).
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
5.2.1 General
Next items are applicable to all Service Modes or are general.
Life Timer
During the life time cycle of the TV set, a timer is kept (called “Op. Hour”). It counts the normal operation hours (not the Stand-by hours). The actual value of the timer is displayed in SDM and SAM in a decimal value. Every two soft-resets increase the hour by +1. Stand-by hours are not counted.
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: “AAAAAAB-XX.YY”, where:
AAAAAA is the chassis name: L11M11.
B is the region indication: E= Europe, A= AP/China, U= NAFTA, L= LATAM.
XX is the main version number: this is updated with a major change of specification (incompatible with the previous software version). Numbering will go from 01 - 99 and AA ­ZZ. – 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,

Service Modes, Error Codes, and Fault Finding
EN 20 L11M1.1L LA5.
5.2.2 Service Default Mode (SDM)
Purpose
Set the TV in SDM mode in order to be able to create a pre­defined setting for measurements to be made. In this platform, a simplified SDM is introduced (without protection override and without tuning to a predefined frequency).
Specifications
Set linear video and audio settings to 50%, but volume to 25%. Stored user settings are not affected.
Set Smart Picture to “Game”.
Set Smart Sound to “Standard”.
Tune channel to:
- for analogue SDM: channel 3 (61.25 MHz)
- for digital SDM: channel 26 (545.143 MHz).
For digital SDM: set PID default from the stream.
All service-unfriendly modes (if present) are disabled, since they interfere with diagnosing/repairing a set. These service unfriendly modes are: – (Sleep) timer. – Blue mute/Wall paper. – Auto switch “off” (when there is no “ident” signal). – Hotel or hospital mode. – Child lock or parental lock (manual or via V-chip). – Skipping, blanking of “Not favorite”, “Skipped” or
“Locked” presets/channels.
– Automatic storing of Personal Preset or Last Status
settings.
– Automatic user menu time-out (menu switches back/
OFF automatically.
– Auto Volume levelling (AVL).
How to Activate
To activate analogue SDM, use one of the following methods:
Press the following key sequence on the RC transmitter: “062596” directly followed by the MENU button.
Short one of the “Service” pads on the TV board during cold start (see Figure 5-2
). Then press the mains button (remove the short after start-up). Caution: When doing this, the service-technician must know exactly what he is doing, as it could damage the television set.
ERR: Shows all errors detected since the last time the buffer was erased in format <xxx> <xxx> <xxx> <xxx> <xxx> (five errors possible).
OP: Used to read-out the option bytes. Ten codes (in two rows) are possible.
How to Navigate
As this mode is read only, there is not much to navigate. To switch to other modes, use one of the following methods:
Command MENU from the user remote will enter the normal user menu (brightness, contrast, color, etc...) with “SDM” OSD remaining, and pressing MENU key again will return to the last status of SDM again.
To prevent the OSD from interfering with measurements in SDM, command “OSD” or “i+” (“STATUS” or “INFO” for NAFTA and LATAM) from the user remote will toggle the OSD “on/off” with “SDM” OSD remaining always “on”.
Press the following key sequence on the remote control transmitter: “062596” directly followed by the INFO[i+]/OK button to switch to SAM (do not allow the display to time out between entries while keying the sequence).
How to Exit
Switch the set to Stand-by by
pressing the standby button on the remote control transmitter or on the television set, or
via a standard RC-transmitter by keying the “00” sequence.
If you switch the television set “off” by removing the mains (i.e., unplugging the television), the television set will remain in SDM when mains is re-applied, and the error buffer is not cleared. The error buffer will only be cleared when the “clear” command is used in the SAM menu.
Note:
If the TV is switched “off” by a power interrupt while in SDM, the TV will show up in the last status of SDM menu as soon as the power is supplied again. The error buffer will not be cleared.
In case the set is accidentally in Factory mode (with an “F” displayed on the screen), pressing and holding “VOL-“ button for 5 seconds and then followed by pressing and holding the “CH-” button for another 5 seconds should exit the Factory mode.

5.2.4 Customer Service Mode (CSM)
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”.
Set volume to 25%.
Set Smart Picture to “Game”.
Set Smart Sound to “Standard”.
Line number for every line (to make CSM language independent).
Set the screen mode to full screen (all contents on screen is visible).
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 a standard remote control transmitter: “123654” (do not allow the display to time out between entries while keying the sequence).

5.3 Service Tools
5.3.1 ComPair
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.
Specifications
Figure 5-3 ComPair II interface connection
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.
ComPair UART interface cable: 3138 188 75051.
Program software can be downloaded from the Philips Service web portal.
Note: For this chassis, “Pgammar” and “T-con NVM” programming (VCOM alignment) are added to ComPair.

5.4.2 How to Read the Error Buffer
You can read the error buffer in three 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 paragraph 5.5 The Blinking LED Procedure
.
•Via ComPair.
5.4.3 Error codes
The “layer 1” error codes are pointing to the defective board. They are triggered by LED blinking when CSM is activated. In the LC10 platform, only two boards are present: the SSB and the PSU/IPB, meaning only the following layer 1 errors are defined:
•2: SSB
3: IPB/PSU
•4: Display
Table 5-1 Error code table
5.4.4 How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
Example (2): the content of the error buffer is “12 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.
5.5.2 Displaying the Entire Error Buffer
Additionally, the entire error buffer is displayed when Service Mode “SDM” is entered.
5.6 Fault Finding and Repair Tips
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.
5.6.1 NVM Editor
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 these, 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.
5.6.2 Load Default NVM Values
It is possible to download default values automatically into the
