Index of this chapter:
3.1 Safety Instructions
3.2 Warnings
3.3 Notes
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. 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.
3.2
•
Warnings
•
•
•
•
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.
3.3
Notes
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
3.3.2
Schematic Notes

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.
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 = × 10-6),
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.
Spare Parts
For the latest spare part overview, consult your Philips Spare
Part web portal.

BGA (Ball Grid Array) ICs
Introduction
For more information on how to handle BGA devices, visit this
URL: http://www.atyourservice-magazine.com. Select
“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.
3.3.5
Lead-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.

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.

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!

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.

ComPair
5.
EN 17
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 I2C or UART commands is necessary,
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 upgrade 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.
Service Alignment Mode (SAM)
How to enter
To enter the factory mode, use the following method:
• Press the following key sequence on the remote control
transmitter: “062596” directly followed by the “INFO”
button.
After entering the service alignment mode, the following screen

Note: The Service Alignment Mode (SAM) are described in
chapter 5. Service Modes, Error Codes, and Fault Finding.
Menu navigation is done with the CURSOR UP, DOWN, LEFT
or RIGHT keys of the remote control transmitter.
6.1
General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
• Power supply voltage: 120 - 230 VAC, 50 ± 10 Hz.
• 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 heatsinks as ground.
• Test probe: Ri > 10 MΩ, Ci < 20 pF.
• Use an isolated trimmer/screwdriver to perform
alignments.
6.1.1
6.2
White Point
•
Choose “TV menu”, “TV Settings” and then “Picture” and
set “Smart Picture” to “Vivid” mode.
White point alignment LCD screens:
• Use a 100% white screen as input signal and set the
following values:
– “Colour temperature”: “Normal”.
– All “White point” values to: “127”.
– “Red BL offset” value to “240” for HDMI source.
– “Green BL offset” value to “240” for HDMI source.
– “Red BL offset” value to “0” for VGA source.
– “Green BL offset” value “0” for VGA source.
Set the correct options:
• In SAM, select “Options” and then “Option numbers”
• Fill in the option numbers for “Group 1” and “Group 2”
according to the set sticker (see also section 6.4 Display
Option Settings).
• Press “OK” on the remote control before the cursor is
moved to the left
• In submenu “Option numbers” select “Store” and press OK
on the RC, or
• In main menu, select “Store” again and press OK on the RC
• Switch the stand to standby.
Warm the set up for >15 minutes.
In case you have a colour analyser:
• Measure with a calibrated contactless (max. 25 mm) 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 (while holding one of the
White point registers R, G or B on 127) 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: ±
0.004, dy: ± 0.004.
• Repeat this step for the other colour temperatures that
need to be aligned.
• When finished press “OK” on the RC and then press
STORE (in the SAM root menu) to store the aligned values
to the NVM.
• Restore the initial picture settings after the alignments.

Software 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 “RGB Align” and go to one of the sub menus.
The alignments are explained below.
The following item can be aligned:
• White point.
To store the data:
• Press OK on the RC before the cursor is moved to the
left.
• In main menu select “Store” and press OK on the RC.
• Press MENU on the RC to switch back to the main menu.
• Switch the set to stand-by mode.
If you do not have a colour analyser, you can use the default
values. This is the next best solution. The default values are
average values coming from production.
• Select a “COLOUR TEMPERATURE” (e.g. “COOL”,
“NORMAL”, or “WARM”).
• Set the White point “RED”, “GREEN” and “BLUE” default
values according to the values in Table 6-2.
• When finished press OK on the RC, then press STORE (in
the SAM root menu) to store the aligned values to the NVM.
• Restore the initial picture settings after the alignments.
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

Reset of Repaired SSB
A very important issue towards a repaired SSB from a service
repair shop implies the reset of the NVM on the SSB.
A repaired SSB in service should get the service Set type
“00PF0000000000” and Production code “00000000000000”.
Also the virgin bit is to be set. To set all this, you can use the
ComPair tool.

Signal paths
RGB
Analogue RGB signals are transferred by the MT8222 to a
digital signal by the internal A/D converter. The MT8222
generates an LVDS signal to the TL2428 on-chip TCON which
drives the LCD display.
HDMI
HDMI signals are further processed digitally by the MT8222.
The MT8222 generates an LVDS signal to the TL2428 on-chip
TCON which drives the LCD display.
Component Input
Component signals are processed by the MT8222. The
MT8222 generates an LVDS signal to the TL2428 on-chip
TCON which drives the LCD display.
Audio is separately processed by the MT8222 and further
processed by the CS4344 and then the audio amplifier.
RF Input
RF input signals are demodulated by the TDA9885 IF
demodulator and further processed by the MT8222. The signal
is then split into an video and an audio part.
2010-Mar-12
The video signal is further processed by the MT8222 which
generates an LVDS signal to the TL2428 on-chip TCON which
drives the LCD display.
The audio signal is further processed by the MT8222 and split
