3.1 Safety Instructions
3.2 Warnings
3.3 Notes
3.4 Abbreviation List
3.1Safety 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. Of de set
ontploft!
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.
picture carrier at 475.25 MHz for PAL, or 61.25 MHz for
NTSC (channel 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.
3.3.2Schematic 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 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
nano-farads (n =× 10
•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.

“Magazine”, then go to “Repair downloads”. Here you will find
Information on how to deal with BGA-ICs.

. Select

-6
),
).
3.2Warnings
•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.
3.3Notes
3.3.1 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 with a colour bar signal and stereo
sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and
3.3.5Lead-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. 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 avoid mixed regimes. If this cannot be avoided, carefully
clear the solder-joint from old tin and re-solder with new tin.

3.3.6 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.
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
example below it is 2006 week 17). The 6 last digits contain the
serial number.

3.3.7Board 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!
3.3.8 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.

5.1Measurement Conditions
Perform measurements under the following conditions:
•Service Default Mode.
•Video: Colour bar signal.
•Audio: 3 kHz left, 1 kHz right.
5.2Service Modes
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).
Service Default mode (SDM) and Service Alignment Mode
(SAM) offer several features for the service technician, while
the Customer Service Mode (CSM) is used for communication
between the call centre and the customer.
This chassis also offers the option of using ComPair, a
hardware interface between a computer and the TV chassis. It
offers the abilities of structured troubleshooting, error code
reading, and software version read-out for all chassis.
(see also section 5.3.1 ComPair
5.2.1 Service Default Mode (SDM)
Purpose
To start the blinking LED procedure where only layer 2 errors
are displayed (see also section 5.4 Error Codes
How to Activate SDM
Use the standard RC-transmitter and key in the code “062596”,
directly followed by the “MENU” (or HOME) button.
After activating this mode, “SDM” will appear in the upper right
corner of the screen (when a picture is available).
How to Navigate
When the “MENU” (or HOME) button is pressed on the RC
transmitter, the set will toggle between the SDM and the normal
user menu (with the SDM mode still active in the background).
How to Exit SDM
Switch the set to STAND-BY via the RC-transmitter.
5.2.2 Service Alignment Mode (SAM)
Purpose
•To perform (software) alignments.

– Op. Hours. During the life time cycle of the TV, a life
timer is kept. It counts the normal operation hours, not
the Stand-by hours. The actual value of the life timer is
displayed in SAM in decimal value. For every two startups the counter increases by one. Min. 5 digits are
displayed in decimal digits. In detail:
•Every 2x cold start-ups, to display a picture,
increases the counter by 1 (i.e. interrupt the mains
supply 2x while the set is ON).
•Every 2x warm start-ups (from Stand-by), to
display a picture, increases the counter by 1.
•Every hour of normal operating increases the
counter by 1 (i.e. if a set is continue ON for 2 hours,
then increase the counter by 2).
•Stand-by hours are NOT counted.

5.2.3 Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer or the Customer Helpdesk. The service
technician can then ask the customer to activate the CSM, in
order to identify the status of the set. Now, the service
technician can judge the severity of the complaint. In many
cases, he can advise the customer how to solve the problem,
or he can decide if it is necessary to visit the customer
The CSM is a read only mode; therefore, modifications in this
mode are not possible
When CSM is activated:
•A test pattern will be displayed during 3 s. This test pattern
is generated by the MT822x video processor. So if this test
pattern is shown, it could be determined that the back end
video chain (MT822x, LVDS, and display) of the SSB is
working.
•The LAYER 1 error is displayed via the blinking front LED.
Only the latest error is displayed. See also section 5.4 Error
Codes.
How to Activate CSM
Key in the code “123654” via the standard RC transmitter.
Note: Activation of the CSM is only possible if there is no (user)
menu on the screen!
How to Navigate
By means of the “Arrow up/down” button on the RC-transmitter,
one can navigate through the menus.

Service Modes, Error Codes, and Fault Finding
5.3Service Tools
5.3.1ComPair
Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips
Consumer Electronics products. and offers the following:
1. ComPair helps 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. No
knowledge on I
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
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The 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).
The ComPair fault finding program is able to determine the
problem of the defective television, by a combination of
automatic diagnostics and an interactive question/answer
procedure.
How to Connect
This is described in the chassis fault finding database in
ComPair.

5.4Error Codes
5.4.1Introduction
The error code buffer contains all detected errors since the last
time the buffer was erased. The buffer is written from top to
bottom (or left to right), new errors are logged at the top/left
side, and all other errors shift one position to the bottom/right.
When an error occurs, it is added to the list of errors, provided
the list is not full. When the error buffer is full, then the new error
is not added, and the error buffer stays intact (history is
maintained).
To prevent that an occasional error stays in the list forever, the
error is removed from the list after more than 50 hrs. of
operation/
There is a simple blinking LED procedure for board level repair
(home repair) the so called LAYER 1 errors, next to the existing
errors which are LAYER 2 errors:
•LAYER 1 errors are one digit errors
•LAYER 2 errors are two digit errors.
When is LAYER 1 or 2 available:
•In CSM mode: When entering CSM: error LAYER 1 will be
displayed by blinking LED. Only the latest error is shown.
•In SDM mode: When SDM is entered via Remote Control
code, LAYER 2 is displayed via blinking LED.
Error display on screen:
•In CSM, no error codes are displayed on screen.
•In SAM, the complete error list is shown.
If possible, check the entire contents of the error buffer. In
some situations, an error code is only the result of another error
code and not the actual cause (e.g. a fault in the protection
detection circuitry can also lead to a protection).
In case of non-intermittent faults, clear the error buffer before
starting to repair (before clearing the buffer, write down the
content, as this history can give significant information). This to
ensure that old error codes are no longer present.
5.4.2How to Read the Error Buffer
Use one of the following methods:
•On screen via SAM (only when a picture is visible). E.g.:
– 000 000 000 000 000: No errors detected
– 017 000 000 000 000: Error code 17 is the last and only
detected error.
– 015 017 000 000 000: Error code 17 was first detected
and error code 15 is the last detected error.
•Via 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.
•Software is available via the Philips Service web portal.
•ComPair serial interface cable (using 3.5 mm Mini Jack
connectors): 3138 188 75051.
Note: When having problems, please contact the local support
desk.
2009-Jun-05
5.4.3How to Clear the Error Buffer
Use one of the following methods:
•By activation of the “Clear Codes” command in the SAM
menu.
•With a normal RC, key in sequence “062599” followed by
“OK”.
Service Modes, Error Codes, and Fault Finding
EN 15TCM3.1L LA5.
5.4.4 Error Codes
Take notice that some errors need several minutes before they
start blinking or before they will be logged. So in case of
problems wait 2 minutes from start-up onwards, and then
check if the front LED is blinking or if an error is logged.

5.5The Blinking LED Procedure (LAYER-2 codes)
5.5.1Introduction
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 that is capable of storing the
last five errors that occurred. This is useful if the OSD is not
working properly.
Errors can also be displayed by the blinking LED procedure.
The method is to repeatedly let the LED pulse with as many
pulses as the error code number, followed by a time period of
1.5 seconds in which the LED is “off”. Then this sequence is
repeated.
E.g. 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 RC
command terminates this sequence.
Displaying the entire error buffer
The entire error buffer can be displayed when service mode
“SDM” is entered (by remote control command
062596<MENU>). When in protection, this sequence will not
work, but than LAYER-1 error code should suffice.
In order to avoid confusion with RC signal reception blinking,
this blinking procedure is terminated when a RC command is
received.
5.5.2How to Activate
Use one of the following methods:
•Activate the CSM. The blinking front LED will show only
the latest LAYER-1 error.
•Activate the SDM. The blinking front LED will show the
entire contents of the LAYER-2 error buffer.

•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 heat sinks as ground.
•Test probe: Ri > 10 MΩ, Ci < 20 pF.
•Use an isolated trimmer/screwdriver to perform
alignments.

•Activate SAM mode and select “RGB Align”.
White point alignment LCD screens:
•Use a 100% white screen on HDMI-1 as input signal and
set the following values:
– “Colour temperature”: “Cool”.
– All “R/G/B_Gain” values to: “127”.
– All “R/G/B_Offset” values to: “240”.
In case colour analyser can be used:
•Measure with a calibrated contactless colour analyser in
the centre of the screen. Consequently, the measurement
needs to be done in a dark environment.
•Adjust the correct x,y coordinates by means of decreasing
the value of one or two other white points to the correct x,y
coordinates (see Table 6-1
). Tolerance dx, dy: ± 0.004.
Only the “Cool” colour temperature needs to adjust.
•When finished, select “Store” in the “RGB Align” sub menu,
and press “OK” on the RC to store the aligned values to the
NVM.
•Restore the initial picture settings after the alignments.
Put the set in SAM mode (see chapter 5. Service Modes, Error
Codes, and Fault Finding). The SAM menu will now appear on
the screen. Select the appropriate alignment and go to one of
the sub menus with the “arrow right” button. The alignments are
explained below.
The following items can be aligned:
•Tuner AGC.
•White point.
•ADC calibration of VGA and YPbPr inputs.
To store the data:
•When displayed, select “Store” in the related sub menu and
press the “OK” button on the RC. Screen text will change
from “DO” to “OK”
•Press the MENU/House button on the RC.
•Switch the set to Stand-by mode.
For the next alignments, supply the following test signals via a
video generator to the RF input:
•EU/AP-PAL models: a PAL B/G TV-signal with a signal
strength of at least 1 mV and a frequency of 475.25 MHz
•US/AP-NTSC models: an NTSC M/N TV-signal with a
signal strength of at least 1 mV and a frequency of 61.25
MHz (channel 3).
•LATAM models: an NTSC M TV-signal with a signal
strength of at least 1 mV and a frequency of 61.25 MHz
(channel 3).

In case no colour analyser is available, the default values
can be used. This is the next best solution. The default values
are average values coming from production.
•Select the “Cool” colour temperature.
•Set the RED, GREEN and BLUE default values according
to the values in the “White tone default settings” table.
•When finished, select “Store” in the “RGB Align” sub menu,
and press “OK” on the RC to store the aligned values to the
NVM.
•Restore the initial picture settings after the alignments.

6.3.3 Auto ADC
Purpose: For correct gray- and colour scale values of the VGA
and YPbPr inputs.
How to align the VGA/PC input:
1. Provide a 1024 × 768 @ 60 Hz test signal with White/Black squares to the VGA input.
2. Select “Auto ADC” in the SAM menu.
3. Press the “Arrow right” button on the RC.
4. Press “OK” on the RC.
5. Wait until OSD shows “Auto ADC - OK”.
How to align the YPbPr inputs (CVI-1 and CVI-2):
1. Provide a 1024 × 768 @ 60 Hz test signal with 100% 8 step colour bar to the YPbPr input.
2. Rest is the same as for the VGA input.
6.4Option Settings
6.4.1 Introduction
The microprocessor communicates with a large number of I
ICs in the set. To ensure good communication and to make
digital diagnosis possible, the microprocessor has to know
which ICs to address, and what brand and type of display is
used.
•The new option setting is only active after the TV is
switched “off/on” with the mains switch (the NVM is then
read again).
6.5Reset of Repaired SSB
When a repaired SSB will be used in an other TV, it is very
important that the correct info is written into the NVM w.r.t.
12NC of the SSB, production serial number of the TV, 12NC of
display and PSU, etc.
To set all this, the ComPair tool can be used, or the NVM can
be edited directly via the NVM editor (in SAM). Find below the
addresses of these items. Use the decimal values.
In case of a display replacement, reset the “Operation hours” to
“0”, or to the operation hours of the replacement display.

6.4.2 Display code
Changing the display option code via a standard RC
Key in the code “0 6 2 5 9 8 MENU x x x” (where x x x is the 3
digit decimal display code of the used display *).
Tips:
•Keep the RC close to the IR receiver, and make sure the
LED blinks when entering a code.
•Key in all codes in one sequence, without pauses.
If the above action is successful, the front LED will go out as an
indication that the RC sequence was correct. After the display
option is changed in the NVM, the TV will go to the Stand-by
mode. If the NVM was corrupted or empty before this action, it
will be initialized first (loaded with default values). This
initializing can take up to 20 seconds.
