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

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.

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.

Service Modes and Fault Finding

Service Modes
The Service Mode feature is split into five parts:
• Factory Mode.
• Customer Service Mode (CSM).
The Factory mode offer features, which can be used by the Service engineer to repair/align a TV set. Some features are:
• Make alignments (e.g. White Tone), reset the error buffer
(Factory Mode).
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.
Note: For the new model range, a new remote control (RC) is used with some renamed buttons. This has an impact on the activation of the Service modes. For instance the old “MENU” button is now called “HOME” (or is indicated by a “house” icon).

Software Identification, Version, and Cluster
The software ID and version will be shown in the main menu display of CSM.
The screen will show: “AAAAB-X.YYY”, where:
• AAAA is the chassis name: TPS141A x.yyy.
• B is the region indication: E = Europe, A = AP/China, U = NAFTA, L = LATAM.
• 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 - 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.
• YYY is the sub version number: this is updated with a minor change (backwards compatible with the previous versions). Numbering will go from 000 - 999.
- If the sub version number changes, the new version number is written in the NVM.
- If the NVM is refreshed, the software identification, version, and cluster will also be written to NVM.

How to Activate the Factory mode
To activate the Factory mode, use the following method:
• Press the following key sequence on the remote control transmitter: from the “Home screen” press “1999”, directly followed by the “Back” button. Do not allow the display to time out between entries while keying the sequence.
After entering the Factory mode, the following items are displayed,

Factory mode overview

How to Exit the Factory mode
Use one of the following methods:
• Select EXIT_FACTORY from the menu and press the “OK” button.
Note: When the TV is switched “off” by a power interrupt, or normal switch to “stand-by” while in the factory mode, the TV will show up in “normal operation mode” as soon as the power is supplied again. The error buffer will not be cleared.

Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and information on the TV’s operation settings. The call center can instruct the customer (by telephone) to enter CSM in order to identify the status of the set. This helps the call center to diagnose problems and failures in the TV set 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”.

• 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 CSM
To activate CSM, press the following key sequence on a standard remote control transmitter: “456987” (do not allow the display to time out between entries while keying the sequence).
After entering the Customer Service Mode, the following items are displayed.
Note: Activation of the CSM is only possible if there is no (user) menu on the screen

Contents of CSM
Set Type This information is very helpful for a helpdesk/workshop as reference for further diagnosis. In this way, it is not necessary for the customer to look at the rear of the TV-set. Note that if an NVM is replaced or is initialized after corruption, this set type has to be re-written to NVM.
Production code Displays the production code (the serial number) of the TV. Note that if an NVM is replaced or is initialized after corruption, this production code has to be re-written to NVM.
HDCP keys Indicates the validity of the HDMI keys (or HDCP keys). In case these keys are not valid and the customer wants to make use of the HDMI functionality, the SSB has to be replaced.

NVM name Detects and displays NVM name.
Software Version Displays the software version.
RS232 Display RS232.
TV Region Display TV region.
LCD display panel 12NC NVM read/write.
SSB Gives an identification of the SSB as stored in NVM. Note that if an NVM is replaced or is initialized after corruption, this identification number has to be re-written to NVM. This identification number is the 12NC number of the SSB.
PSU 12NC NVM read/write.
How to Exit CSM
To exit CSM, use one of the following methods.
• Press the MENU/HOME button on the remote control transmitter.
• Press the POWER button on the remote control transmitter.
• Press the POWER button on the television set.

Reset of Repaired SSB [Small Signal Board]
A very important issue towards a repaired SSB from a Service repair shop (SSB repair on component level) implies the reset of the NVM on the SSB.
After a repaired SSB has been mounted in the set (set repair on board level), the type number (CTN) and production code of the TV has to be set according to the type plate of the set.

SSB Identification
SSB’s of this chassis are identified by a “715” code on the SSB.
715Axxxx-Nnn-MMM-OOOO
• 715 main category, Printed Wiring Board
• Axxxx sub category, sequential coding number
• Nnn Version code
• N Development number
• nn Production number
• MMM Mounting variation code
• OOOO Optional variation code
Make sure when replacing an SSB the SSB identification codes match the replacement board.

Power Supply Unit
All power supplies are a block box for Service. When defective, a new board must be ordered and defective one must be returned,unless the main fuse of the board is broken. Always replace a defective fuse with one with the correct specifications. This part is available in the regular market.
Consult the Philips Service web portal for the order codes of the boards.
Important delta’s with the TPS14.1A LA classis platform are:
• New power architecture for LED backlight
• “Boost” signal is now a PWM-signal + continuous variable.
The control signals are:
• Stand-by
• Lamp “on/off”
• DIM (PWM) (not for PSDL)
In this manual, no detailed information is available because of design protection issues.
The output voltages to the chassis are:
• +4V7-STANDBY (Stand-by mode only)
• +12V (on-mode)
• +Vsnd (+24V) (audio power) (on-mode)
• +24V (bolt-on power) (on-mode)

Output to the display; in case of
- IPB: High voltage to the LCD panel
- PSL and PSLS (LED-driver outputs)
- PSDL (high frequent) AC-current.

Diversity
The diversity in power supply units is mainly determined by the diversity in displays.
The following displays can be distinguished:
• CCFL/EEFL backlight: power board is conventional IPB
• LED backlight:
- side-view LED without scanning: PSL power board
- side-view LED with scanning: PSLS power board
- direct-view LED without 2D-dimming: PSL power board
- direct-view LED with 2D-dimming: PSDL power board.
PSL stands for Power Supply with integrated LED-drivers.
PSLS stands for a Power Supply with integrated LED-drivers with added Scanning functionality (added microcontroller).
PSDL stands for a Power Supply for Direct-view LED backlight with 2D-dimming.

DC/DC Converters
The on-board DC/DC converters deliver the following voltages (depending on set execution):
• +5V-STANDBY, permanent voltage for the Stand-by controller
• +3V3-STANDBY, power supply for LED/IR receiver and controls
• +12V, input from the power supply for the panel common (active mode)
• +24V, input from the power supply for the amplifier
• +1V2, from the power supply for the scaler IC MST6931
• +1V8, supply voltage for DDR2 (diagram B03B) • +3V3, general supply voltage
• +3.3V-TUN, supply voltage for tuner
• +3.3V, supply voltage for Headphone AMP
