Precautions, Notes, and Abbreviation List
3.Precautions, Notes, and Abbreviation List
Index of this chapter:
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.
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).
•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 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.
3.3.3Spare Parts
For the latest spare part overview, consult your Philips Spare
Part web portal.
3.3.4BGA (Ball Grid Array) ICs
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”.
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

Precautions, Notes, and Abbreviation List
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.

5.3 Stepwise Start-up
5.4 Service Tools
5.5 Software Upgrading
5.6 The Blinking LED Procedure
5.7 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 Alignment Mode (SAM).
•Factory Mode.
•Customer Service Mode (CSM).
•Computer Aided Repair Mode (ComPair).
SAM and 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
(SAM and Factory Mode).
•Display information (“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.
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 SAM and CSM.
The screen will show: “AAAAB-X.YYY”, where:
•AAAA is the chassis name: TPN149E x.yy.
•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.
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 back to div. table 6-3
is 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.

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).
5.2.1 General
Next items are applicable to all Service Modes or are general.
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

5.2.4 Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and
information on the TVs operation settings.The call centre can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set.This helps the call centre 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”.
•Line number for every
line (to make CSM language independent).
•Set the screen mode to full
screen (all contents on screen is visible).
•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.

5.4Service Tools
5.4.1 ComPair
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
automatic diagnostics and an interactive question/answer
procedure.
How to Connect
This is described in the chassis fault finding database in
ComPair.

•Once the upgrade is finished, use the PC to remove the TV
software from the USB portable memory.
5.6The Blinking LED Procedure
5.6.1Introduction
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, which 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 front LED pulse with as
many pulses as the error code number, followed by a period of
1.5 seconds in which the LED is “off”. Then this sequence is
repeated.
Example (1): 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 the sequence. Error code LED blinking is
in red color.
Example (2): the content of the error buffer is “12 9 6 0 0” After
entering SDM, the following occurs.
•1 long blink of 5 seconds to start the sequence.
•12 short blinks followed by a pause of 1.5 seconds.
•9 short blinks followed by a pause of 1.5 seconds.
•6 short blinks followed by a pause of 1.5 seconds.
•1 long blink of 1.5 seconds to finish the sequence.
•The sequence starts again with 12 short blinks.
5.5.6Content and Usage of the One-Zip Software File
Below you find a content explanation of the One-Zip file, and
instructions on how and when to use it. Only files that are
relevant for Service are mentioned here.
•EDID_clustername.zip: Contains the EDID content of the
different EDID NVMs. See ComPair for further instructions.

5.7Fault Finding and Repair Tips
Note:
•It is assumed that the components are mounted correctly
with correct values and no bad solder joints.
•Before any fault finding actions, check if the correct options
are set.
5.7.1 NVM Editor
In some cases, it can be convenient if one directly can change
the NVM contents. This can be done with the “NVM Editor” in
SAM mode. With this option, single bytes can be changed.
Caution:
•Do not change these, without understanding the function of
each setting, because incorrect NVM settings may
seriously hamper the correct functioning of the TV set!
•Always write down the existing NVM settings, before
changing the settings. This will enable you to return to the
original settings, if the new settings turn out to be incorrect.
5.7.2Load Default NVM Values
It is possible to upload the default values to the NVM with
ComPair in case the SW is changed, the NVM is replaced with
a new (empty) one, or when the NVM content is corrupted.
After replacing an EEPROM (or with a defective/no EEPROM),
default settings should be used to enable the set to start-up and
allow the Service Default Mode and Service Alignment Mode to
be accessed.
5.7.10 Display option code
Attention: In case the SSB is replaced, always check the Panel
Code in CSM, even when picture is available. Performance
with the incorrect display option code can lead to unwanted
side-effects for certain conditions.
5.7.3 No Picture
When you have no picture, first make sure you have entered
the correct display code. See paragraph 6.4 Option Settings
the instructions. See also back to div. table 6-3
5.7.4Unstable Picture via HDMI input
Check (via ComPair or factory mode) if HDMI EDID data is
properly programmed.
5.7.5No Picture via HDMI input
Check if HDCP key is valid. This can be done in CSM.
5.7.6TV Will Not Start-up from Stand-by
Possible Stand-by Controller failure. Re-flash the software.
5.7.7Audio Amplifier
The Class D-IC U606 has a powerpad for cooling. When the IC
is replaced it must be ensured that the powerpad is very well
pushed to the PWB while the solder is still liquid. This is needed
to insure that the cooling is guaranteed, otherwise the Class
D-IC could break down in short time.
.
for
5.7.8 CSM
When CSM is activated and there is a USB memory stick
connected to the TV, the software will dump the complete CSM
content to the USB memory stick. The file (Csm.txt) will be
saved in the root of the USB memory stick.
5.7.9Loudspeakers
Make sure that the volume is set to minimum during
disconnecting the speakers in the ON-state of the TV. The
audio amplifier can be damaged by disconnecting the speakers
during ON-state of the set!

In case you have a colour analyser:
•Measure with a calibrated (phosphor- independent) color
analyser (e.g. Minolta CA-210) 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 max. value) by means of
decreasing the value of one or two other white points to the
correct x, y coordinates (see Table 6-1 White D alignment
values). Tolerance: dx: ± 0.003, dy: ± 0.003.
•Repeat this step for the other colour Temperatures that
need to be aligned.
•When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.

6.3Software Alignments
Put the set in SAM mode (see Chapter 5. Service Modes 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 items can be aligned:
•White point.
To store the data:
•Press OK on the RC before the cursor is moved to the left.
•Select “Store” and press OK 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).

•Activate SAM.
•Select “RGB Align.” and choose a color temperature.
•Use a 100% white screen as input signal and set the
following values:
– “Red BL Offset” and “Green BL Offset” to “7” (if
present).
– All “White point” values initial to “128”.
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 (statistics).
6.3.2Display Adjustment
You can use the default values. The default values are average
values coming from production.
•Enter SAM mode.
•Select a colour temperature (e.g. COOL, NORMAL, or
WARM).
•Set the RED, GREEN and BLUE default values according
to the values in back to div. table 6-2
.
•When finished press OK on the RC, then press STORE to
store the aligned values to the NVM.
•Restore the initial picture settings after the alignments.
This group setting of colour temperature will be applied
automatically to the TV / VGA / HDMI / AV sources.
6.4Option Settings
6.4.1Introduction
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. The presence / absence of these
NT72567 ICs is made known by the option codes.
Notes:
•After changing the option(s), save them by pressing the OK
button on the RC before the cursor is moved to the left,
select STORE and press OK on the RC.
•The new option setting is only active after the TV is
switched “off” / “stand-by” and “on” again with the mains
switch (the NVM is then read again).
6.4.2Option Code Overview
Enter SAM mode to check the option codes. they could not be
edited in the NVM.
6.4.3Display Code Overview
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 back to div. table 6-3
the Display Code, restart the set immediately.
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.
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 or use the “NVM editor” and “Dealer options”
items in SAM (do not forget to “store”).
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. For
this, you can use the NVM editor in SAM. The loading of the
CTN and production code can also be done via ComPair
(Model number programming).
In case of a display replacement, reset the “Operation hours
display” to “0”, or to the operation hours of the replacement
display.
