Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
EN 5LC4.41A AA2.
Index of this chapter:
2.1 Safety Instructions
2.2 Warnings
2.3 Notes
2.1Safety 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 Mohm and 12 Mohm.
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.
2.2Warnings
•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. Available
ESD protection equipment:
– Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and earth cable) 4822
310 10671.
– Wristband tester 4822 344 13999.
•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.
2.3Notes
2.3.1General
•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 (see chapter 5) 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.
•The semiconductors indicated in the circuit diagram and in
the parts lists, are interchangeable per position with the
semiconductors in the unit, irrespective of the type
indication on these semiconductors.
•Manufactured under license from Dolby Laboratories.
“Dolby”, “Pro Logic” and the “double-D symbol”, are
trademarks of Dolby Laboratories.
2.3.2Schematic 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 kohm).
•Resistor values with no multiplier may be indicated with
either an "E" or an "R" (e.g. 220E or 220R indicates 220
ohm).
•All capacitor values are given in micro-farads (µ= x10
nano-farads (n= x10
•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 in the Spare Parts
List. Therefore, always check this list when there is any
doubt.
2.3.3Rework on BGA (Ball Grid Array) ICs
General
Although (LF)BGA assembly yields are very high, there may
still be a requirement for component rework. By rework, we
mean the process of removing the component from the PWB
and replacing it with a new component. If an (LF)BGA is
removed from a PWB, the solder balls of the component are
deformed drastically so the removed (LF)BGA has to be
discarded.
Device Removal
As is the case with any component that, is being removed, it is
essential when removing an (LF)BGA, that the board, tracks,
solder lands, or surrounding components are not damaged. To
remove an (LF)BGA, the board must be uniformly heated to a
temperature close to the reflow soldering temperature. A
uniform temperature reduces the risk of warping the PWB.
To do this, we recommend that the board is heated until it is
certain that all the joints are molten. Then carefully pull the
component off the board with a vacuum nozzle. For the
appropriate temperature profiles, see the IC data sheet.
Area Preparation
When the component has been removed, the vacant IC area
must be cleaned before replacing the (LF)BGA.
Removing an IC often leaves varying amounts of solder on the
mounting lands. This excessive solder can be removed with
either a solder sucker or solder wick. The remaining flux can be
removed with a brush and cleaning agent.
After the board is properly cleaned and inspected, apply flux on
the solder lands and on the connection balls of the (LF)BGA.
Note: Do not apply solder paste, as this has been shown to
result in problems during re-soldering.

).
Page 6
EN 6LC4.41A AA2.
Safety Instructions, Warnings, and Notes
Device Replacement
The last step in the repair process is to solder the new
component on the board. Ideally, the (LF)BGA should be
aligned under a microscope or magnifying glass. If this is not
possible, try to align the (LF)BGA with any board markers.
So as not to damage neighbouring components, it may be
necessary to reduce some temperatures and times.

2.3.4 Lead-free Solder
Philips CE is producing lead-free sets (PBF) from 1.1.2005
onwards.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 5 and 6 refer to the production year, digits
7 and 8 refer to production week (in example below it is 1991
week 18).

•Use only original spare-parts listed in the Service-Manuals.
Not listed standard material (commodities) has to be
purchased at external companies.
•Special information for lead-free BGA ICs: these ICs will be
delivered in so-called "dry-packaging" to protect the IC
against moisture. This packaging may only be opened
shortly before it is used (soldered). Otherwise the body of
the IC gets "wet" inside and during the heating time the
structure of the IC will be destroyed due to high (steam-)
pressure inside the body. If the packaging was opened
before usage, the IC has to be heated up for some hours
(around 90°C) for drying (think of ESD-protection!).
Do not re-use BGAs at all!
•For sets produced before 1.1.2005, containing leaded
soldering tin and components, all needed spare parts will
be available till the end of the service period. For the repair
of such sets nothing changes.
In case of doubt whether the board is lead-free or not (or with
mixed technologies), you can use the following method:
•Always use the highest temperature to solder, when using
SAC305 (see also instructions below).
•De-solder thoroughly (clean solder joints to avoid mix of
two alloys).
Caution: For BGA-ICs, you must use the correct temperatureprofile, which is coupled to the 12NC. For an overview of these
profiles, visit the website www.atyourservice.ce.philips.com
(needs subscription, but is not available for all regions)
You will find this and more technical information within the
"Magazine", chapter "Repair downloads".
For additional questions please contact your local repair help
desk.
Figure 2-1 Serial number example
Regardless of the special lead-free logo (which is not always
indicated), one must treat all sets from this date onwards
according to the rules as described below.
P
b
Figure 2-2 Lead-free logo
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
•Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106. 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 stabilise 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 stabilised 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.
2.3.5Alternative BOM identification
In September 2003, Philips CE introduced a change in the way
the serial number (or production number, see Figure 2-1) is
composed. From this date on, the third digit in the serial
number (example: AG2B0335000001) indicates the number of
the alternative BOM (Bill of Materials used for producing the
specific model of TV set). 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 O.E.M.s.
By looking at the third digit of the serial number, the service
technician can see if there is more than one type of B.O.M.
used in the production of the TV set he is working with. He can
then consult the At Your Service Web site, where he can type
in the Commercial Type Version Number of the TV set (e.g.
28PW9515/12), after which a screen will appear that gives
information about the number of alternative B.O.M.s used.
If the third digit of the serial number contains the number 1
(example: AG1B033500001), then there is only one B.O.M.
version of the TV set on the market. If the third digit is a 2
(example: AG2B0335000001), then there are two different
B.O.M.s. Information about 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.
2.3.6Practical 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.

4.2Service Position
First, put the TV set in its service position. Therefore, place it
upside down on a table top (use a protection sheet or foam
bars).
4.2.1The Foam Bars
E_06532_018.eps
Figure 4-2 Foam bars
The foam bars (order code 3122 785 90580) can be used for
all types and sizes of Flat TVs. By laying the plasma TV flat on
the (ESD protective) foam bars, a stable situation is created to
perform measurements and alignments. By first placing a
mirror flat on the table under the TV you can easily see if
something is happening on the screen.

5.1Test Points
This chassis is equipped with test points. In the schematics,
test points are indicated with a rectangle box around Fxxx or
Ixxx, in the layouts with a half-moon.
Perform measurements under the following conditions:
•Television set in Service Default Mode.
•Video input: Colour bar signal.
•Audio input: 3 kHz left channel, 1 kHz right channel.
5.2Service Modes
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 possibilities of structured troubleshooting, error code
reading, and software version read-out for all chassis.
Minimum requirements for ComPair: a Pentium processor, a
Windows OS, and a CD-ROM drive (see also paragraph
"ComPair").
How to Enter
To enter SDM, use one of the following methods:
•Press the following key sequence on the remote control
transmitter: “062596” directly followed by the MENU button
(do not allow the display to time out between entries while
keying the sequence).
•Short one of the "Service" jumpers (component or solder
side) on the TV board during cold start and apply mains
(see Figures "Service jumper"). Then press the mains
button (remove the short after start-up).
Caution: Entering SDM by shorting "Service" jumpers will
override the +8V-protection. Do this only for a short period.
When doing this, the service-technician must know exactly
what he is doing, as it could damage the television set.
•Or via ComPair.

5.4Service Tools
5.4.1 ComPair
Introduction
ComPair (Computer Aided Repair) is a service tool for Philips
Consumer Electronics products. ComPair is a further
development on the European DST (service remote control),
which allows faster and more accurate diagnostics. ComPair
has three big advantages:
1. ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you
systematically through the repair procedures.
2. ComPair allows very detailed diagnostics (on I
is therefore capable of accurately indicating problem areas.
You do not have to know anything about I
yourself because ComPair takes care of this.
3. ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the
microprocessor is working) and all repair information is
directly available. When ComPair is installed together with
the Force/SearchMan electronic manual of the defective
chassis, schematics and PWBs are only a mouse click
away.
Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The ComPair interface box is connected to the PC via a serial
(or RS-232) cable.
For this chassis, the ComPair interface box and the TV
communicate via a bi-directional service cable via the service
connector(s).
The ComPair fault finding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:
•Automatically (by communicating with the television):
ComPair can automatically read out the contents of the
entire error buffer. Diagnosis is done on I
ComPair can access the I
ComPair can send and receive I
the micro controller of the television. In this way, it is
possible for ComPair to communicate (read and write) to
devices on the I
2
C/UART buses of the TV-set.
•Manually (by asking questions to you): Automatic
diagnosis is only possible if the micro controller of the
television is working correctly and only to a certain extent.
When this is not the case, ComPair will guide you through
the fault finding tree by asking you questions (e.g. Does the
screen give a picture? Click on the correct answer: YES /
NO) and showing you examples (e.g. Measure test-point I7
and click on the correct oscillogram you see on the
oscilloscope). You can answer by clicking on a link (e.g.
text or a waveform picture) that will bring you to the next
step in the fault finding process.
By a combination of automatic diagnostics and an interactive
question / answer procedure, ComPair will enable you to find
most problems in a fast and effective way.

How to Connect
This is described in the chassis fault finding database in
ComPair.
Note: If you encounter any problems, contact your local
support desk.
5.4.2LVDS Tool
Introduction
This service tool (also called “ComPair Assistant 1“) may help
you to identify, in case the TV does not show any picture,
whether the Small Signal Board (SSB) or the display of a Flat
TV is defective.
Furthermore it is possible to program EPLDs with this tool (Byte
blaster). Read the user manual for an explanation of this
feature.
Since 2004, the LVDS output connectors in our Flat TV models
are standardised (with some exceptions). With the two
delivered LVDS interface cables (31p and 20p) you can cover
most chassis (in special cases, an extra cable will be offered).
When operating, the tool will show a small (scaled) picture on
a VGA monitor. Due to a limited memory capacity, it is not
possible to increase the size when processing high-resolution
LVDS signals (> 1280x960). Below this resolution, or when a
DVI monitor is used, the displayed picture will be full size.
Generally this tool is intended to determine if the SSB is
working or not. Thus to determine if LVDS, RGB, and sync
signals are okay.

Note: To use the LVDS tool, you must have ComPair release
2004-1 (or later) on your PC (engine version >= 2.2.05).
For every TV type number and screen size, one must choose
the proper settings via ComPair. The ComPair file will be
updated regularly with new introduced chassis information.

The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, it is displayed at the left side and all other errors shift one
position to the right.
5.5.1How to Read the Error Buffer
You can read the error buffer in 3 ways:
•On screen via the SAM (if you have a picture).
Examples:
– ERROR: 0 0 0 0 0 : No errors detected
– ERROR: 6 0 0 0 0 : Error code 6 is the last and only
detected error
– ERROR: 9 6 0 0 0 : Error code 6 was detected first and
error code 9 is the last detected (newest) error
•Via the blinking LED procedure (when you have no
picture). See “The Blinking LED Procedure”.
•Via ComPair.
5.5.2How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
•By using the CLEAR command in the SAM menu:
– To enter SAM, press the following key sequence on the
remote control transmitter: “062596” directly followed
by the OSD/i+ button (do not allow the display to time
out between entries while keying the sequence).
– Make sure the menu item CLEAR is selected. Use the
MENU UP/DOWN buttons, if necessary.
– Press the MENU RIGHT button to clear the error
buffer. The text on the right side of the “CLEAR” line will
change from “CLEAR?” to “CLEARED”
•If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.
Note: If you exit SAM by disconnecting the mains from the
television set, the error buffer is not reset.
How to Connect
Connections are explained in the user manual, which is packed
with the tool.

Service Modes, Error Codes, and Fault Finding
5.5.3Error Codes
In case of non-intermittent faults, write down the errors present
in the error buffer and clear the error buffer before you begin
the repair. This ensures that old error codes are no longer
present.
If possible, check the entire contents of the error buffer. In
some situations, an error code is only the result of another error
and not the actual cause of the problem (for example, a fault in
the protection detection circuitry can also lead to a protection).

5.6The Blinking LED Procedure
Using this procedure, you can make the contents of the error
buffer visible via the front LED. This is especially useful when
there is no picture.
When the SDM is entered, the front LED will blink the contents
of the error-buffer:
•The LED blinks 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.
Any RC5 command terminates this sequence.
Example of error buffer: 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.
5.7Fault Finding and Repair Tips
Notes:
•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.
5.7.1NVM Editor
In some cases, it can be handy 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 the NVM settings without
understanding the function of each setting, because
incorrect NVM settings may seriously hamper the
correct functioning of the TV set!
•Do not change the Scaler NVM settings, as this will
hamper the DVI / HDMI functionality of the TV set!
•Always note 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
In case a blank NVM is placed or when the NVM content is
corrupted, default values can be downloaded into the NVM.
(For empty NVM replacement, short the SDM with a jumper
and apply the mains voltage. Remember to remove the jumper
after the reload is completed). After the default values are
downloaded, it will be possible to start up and to start aligning
the TV set. This is no longer initiated automatically; to initiate
the download the following action has to be performed:
1. Switch “off” the TV set by disconnecting the AC Power
plug.
2. Short circuit an SDM jumper (keep short-circuited).
3. Press P+ or Ch+ on the local keyboard (and keep it
pressed).
4. Switch on the TV set via the AC Power plug.
5. Keep pressing the P+/Ch+ button until the set has started
up and the SDM is shown.
Alternative method:
1. Go to SAM.
2. Select NVM Editor (not SC NVM Editor).
3. Select ADR (address) to 1 (dec).
4. Change the VAL (value) to 170 (dec).
5. Store the value.
6. Disconnect the mains plug and wait for a few seconds.
7. Reconnect the mains plug and wait until the set goes into
its standby mode (red LED lights up).
8. Restart the set.
5.7.3Flash New Scaler Software
When you need to flash new scaler software, follow the
instructions in ComPair. Make sure you put the set in one of the
Service Modes, SDM/SAM/CSM, before you start flashing.
This reduces the risk of the set hanging during the flashing
procedure.
Power Supply is Correct, but no Green LED
1. Check if the connectors 1K00 are properly inserted.
2. If they are inserted correctly, check if the 3V3 is present.
No Picture Display (blank screen with correct sound
output)
1. Check whether the user menu is visible.
2. If the user menu is OK, activate teletext mode.
3. If teletext is OK, the problem is in the ADC (B18) &
Columbus 3D combfilter (B19), if present (depending on
model, see also paragraph “Teletext Path” in chapter 9).
4. If the user menu is not visible, check if the LCD panel
backlight is ON.
5. If the backlight is OFF, the problem is in the power supply
board or LCD panel. Also check pin 12 (LAMP_ON_OFF)
of 1J02. It should be HIGH during normal operation.
Note: For fault finding purposes, it is important to know the
following: in Pixel Plus and Digital Crystal Clear models, which
have an ADC (B18) and Columbus 3D combfilter (B19), the
digital input of the scaler is used for the digital video path
(Hercules output), whereas the analogue RGB input (analogue
input of the scaler) is only used for teletext. This means that no
mixed mode (video plus teletext simultaneously) is possible. If
there is sound and teletext, but no video and user menu (blank
screen), the digital path (Hercules - ADC - Columbus - Scaler)
is faulty. If there is sound but no teletext, the back-end part
(Scaler - LCD panel) is faulty.
No TV, but PC is Present
1. Check if Hsync_SDTV and Vsync_SDTV are present at pin
1 & pin13 of 7E03.
2. If they are present, check teletext output.
3. If there is no teletext output, the IC TDA150xx may be
defect.

8.3.4ADC Gain and Grey Scale Alignment
The table below shows a number of NVM settings used for
each model of TV set. Be sure to use the correct editor in the
SAM menu (NVM Editor or SC NVM Editor), because the first
one is used for the Hercules NVM, and the second one for the
SCALER (SC) part of the TV set. For further important NVM
settings, see also the other NVM tables elsewhere in this
manual.
Caution:
•Do not change the NVM settings without
understanding the function of each setting, because
incorrect NVM settings may seriously hamper the
correct functioning of the TV set!
•Do not change the Scaler NVM settings, as this will
hamper the DVI functionality of the TV set!
•Always note 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.

The table below shows the NVM settings for panel selection,
based on panel size and manufacturer. Use the SC NVM editor
in the SAM menu to change the panel code at decimal address

Caution:
•Make sure to choose the right panel, because incorrect
NVM settings may seriously hamper the correct
functioning of the TV set!
•Always note 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.

Options OP1...OP7 in the SAM menu can be used for quickly
restoring 64 features or settings of the HERCULES part of the
TV set to their original default factory values (8 groups of 8
features/settings each). When the decimal value of one option
byte OP1...OP7 is changed (see the first table below) then a
group of 8 bits, representing 8 HERCULES options or features,
is changed as well (see the second table below for a detailed
description of the features or settings that are changed).
The second table shows which option byte (OP1...OP7)
represents which group of 8 option bits. Each bit (0...7)
switches a particular HERCULES feature or setting ON or OFF,
depending on its value (1 or 0).
It is also possible to change the features or settings mentioned
in the second table directly at bit level, by means of the NVM
Editor in the SAM menu. In the NVM Editor, first the correct
NVM address (ADR) has to be entered, then the correct value
(VAL, 1 or 0) for each bit (see second table), and finally the
settings have to be stored (STORE). For quickly restoring the
HERCULES part of the TV set to its original factory settings,
however, it is more convenient to simply enter the default
factory settings OP1...OP7 that are given in the first table
below. How to do this, is described in the next paragraph.
How to Change an Option Byte
As has been explained above, an Option byte (OP) represents
a number of different HERCULES options. Changing these
bytes directly makes it possible to set all HERCULES options
very fast. All options are controlled via seven option bytes.
Select the option byte (OP1.. OP7) with the Menu Up/ Down
keys, and enter the new (decimal) value. For the correct
Factory Default settings, see the first table below. For more
detailed information, see the second table.
Leaving the Option submenu saves the changes in the Option
Byte settings. Some changes will only take effect after the set
has been switched “off” and “on” with the AC power switch (cold
start).

If you wish to know which features or settings of the
HERCULES are changed via OP1...OP7, or if you want to
change each option or feature bit by bit, use the more detailed
table below.
Note: the table below contains only part of the NVM settings
that can be changed. A second range of settings and features
can be found in Chapter 5 of this manual, in table NVM Default values. The settings mentioned there can only be changed via
the NVM editor. For further settings, see also the table “ADC
