Index of this chapter:
Safety Instructions
3.1
3.2 Warnings
3.3 Notes
3.4 Abbreviation List
•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.
EN 5TPM9.1AL LA3.
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.
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.
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
picture carrier at 475.25 MHz for PAL, or 61.25 MHz for
NTSC (channel 3).
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 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
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.

Part web portal.

Introduction
For more information on how to handle BGA devices, visit this
URL: http://www.atyourservice-magazine.com
“Magazine”, then go to “Repair downloads”. Here you will find
Information on how to deal with BGA-ICs.
BGA Temperature Profiles
For BGA-ICs, you must use the correct temperature-profile.
Where applicable and available, this profile is added to the IC
Data Sheet information section in this manual.
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.
3.3.6Alternative BOM identification
It should be noted that on the European Service website,
“Alternative BOM” is referred to as “Design variant”.

Precautions, Notes, and Abbreviation List
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.
Figure 3-1 Serial number (example)
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.

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.

5.8 Fault Finding and Repair Tips
5.1Test Points
As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope. However, 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.
5.2Service Modes
The Service Mode feature is split into five parts:
•Service Default Mode (SDM).
•Service Alignment Mode (SAM).
•Factory Mode.
•Customer Service Mode (CSM).
•Computer Aided Repair Mode (ComPair).
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: “AAAAB-X.YYY”, where:
•AAAA is the chassis name: T911A 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.
SDM, SAM and the Factory mode 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).
•Make alignments (e.g. White Tone), reset the error buffer
(SAM and Factory Mode).
•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 I
engineer to quickly diagnose the TV set by reading out error
codes, read and write in NVMs, communicate with ICs and the
micro processor (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 I
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).
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).

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 6-3
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 SSB
related (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.
5.2.2Service 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.
•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 favourite”, “Skipped” or
“Locked” presets/channels.
– Automatic storing of Personal Preset or Last Status
settings.

buffer was erased in format <xxx> <xxx> <xxx> <xxx>
<xxx> (five errors possible).
•OP Used to read-out the option bytes. In this chassis two
times eight option codes are used.
How to Navigate
As this mode is read only, there is nothing to navigate. To
switch to other modes, use one of the following methods:
•Command MENU from the user remote will exit SDM.
•To prevent the OSD from interfering with measurements in
SDM, use the command “Adjust” or “Options” (“STATUS”
or “INFO” for NAFTA and LATAM) from the user remote.
This will switch the OSD “off” while remaining in the SDM
mode. The “SDM” OSD is remains visible in the upper right
corner of the screen. To exit SDM switch to “Stand-by”
mode.
•Press the following key sequence on the remote control
transmitter: “062596” directly followed by the OK button to

5.4.1ComPair
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
micro processor 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
