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,
ly by components identical to the original ones. Any
on
other component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
Safety regulations require that after a repa

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

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
ldering tin. The solder tool must be able:
so
– 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
- 380°C is reached and stabilized at the solder joint.
360°C
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 sold
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.

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 o

If the third digit of the serial n
(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
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
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.

4.2Service 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.

5.1Test 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 four parts:
•Service Default Mode (SDM).
•Service Alignment Mode (SAM).
•Customer Service Mode (CSM).
•Computer Aided Repair Mode (ComPair).

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.
•Solve customer problems without home visit.
ComPair Mode is used for communication between a computer
and a T
engineer to quickly diagnose the TV set by reading out error
codes, read and write in NVMs, communicate with ICs and the
μP (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 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 rename
activation of the Service modes. For instance the old “MENU”
button is now called “HOME” (or is indicated by a “house” icon).

During the life time cycle of the TV set, a timer is ke

Stand-by hours). The actual value of the timer is displayed in

increase the hour by + 1. Stand-by hours are not counted.

5.4.1ComPair
Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips
Cons

1. ComPair helps to quickly get an understanding on how to
repair the chassis in a short and effective
2. ComPair allows very detailed di
capable of accurately indicating problem areas. No
knowledge on I
2
C or UART commands is necessary,
because ComPair takes care of this.
3. ComPair speeds up the repair time since it can
tomatically communicate with the chassis (when the
au
microprocessor is working) and all repair information is
directly available.
4. ComPair features TV software up possibilities.
Specifications
ComPair consists of a Windows based fault find
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 dete

software can be found in the DFU or on the Philips website.
5.5.2Introduction
Philips continuously tries to imp
recommend that the TV software is updated when updates are
available. Software update files can be obtained from the
dealer or can be downloaded from the following websites:
http://www.philips.com/support
Preparing a portable memory for software upgrade
The following requirements have to be met:
1. A personal computer connected to the Internet.

Caution: It is compulsory to connect the TV to the PC a
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 can be
blown!
Note:
1. Only FAT/DOS-formatted flas

7.1Introduction
The TPM8.2E LA platform uses MT5366/MT5135. It supports
decoder and a TV controller offers high integration for
advanced applications. It combines a transport de-multiplexer,
a high definition video decode, an AC3 decode, a dual-link
LVDS/mini-LVDS transmitter, and an NTSC/PAL/SECAM TV
decoder with a 3D comb filter (NTSC/PAL).
7.1.1Implementation
Key components of this chassis are:
•Only new cir
cuits (circuits that are not published recently)
are described.
•Figures can deviate slightly from the actual situation, due
to different set exe
cutions.
•For a good understanding of the following circuit
descriptions, please use the wiring, block (see chapter
9. Block
Diagrams) and circuit diagrams (see chapter
10. Circuit Diagrams and PWB Layouts).Where necessary,
you will find a separate drawing for clarification.

This circuit will provide a “high-to-low” pulse when t
SSB power line goes low. This will trigger the related audio
mute circuit, preventing the audio circuit making uncontrolled
