Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

Index of this chapter:

2.1 Safety Instructions

2.2 Warnings

2.3 Notes

2.1 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.

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.

2.2 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. 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.

2.3 Notes

2.3.1 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 (see chapter 5) with a color 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.

2.3.2 Schematic 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.

2.3.3 BGA (Ball Grid Array) ICs

Introduction

For more information on how to handle BGA devices, visit this
URL: www.atyourservice.ce.philips.com (needs subscription,
not available for all regions). After login, 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,
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.

2.3.4 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 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 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.

),

).

Directions for Use

EN 5LC4.8L LA 3.

• 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.

2.3.5 Alternative BOM identification

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 center (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.

2.3.6 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!

2.3.7 Practical Service Precautions

• It makes sense to avoid exposure to electrical shock.

• Always respect voltages. While some may not be

AG 1A0617 000001

Figure 2-1 Serial number (example)

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.

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.

The foam bars (order code 3122 785 90580 for two pieces) can
be used for all types and sizes of Flat TVs. See figure “Foam
bars” for details. Sets with a display of 42” and larger, require

four foam bars [1].
Caution: Ensure that the foam bars are always supporting the

cabinet and never only the display. Failure to follow these
guidelines can seriously damage the display!
By laying the TV face down on the (ESD protective) foam bars,
a stable situation is created to perform measurements and
alignments. By placing a mirror under the TV, you can monitor
the screen.

5.6 Fault Finding and Repair Tips

5.1 Test Points

In the chassis schematics and layout overviews, the test points
(Fxxx) are mentioned. In the schematics, test points are
indicated with a rectangular box around “Fxxx” or “Ixxx”, in the
layout overviews with a “half-moon” sign.
As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope. 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: Color bar signal.

• Audio: 3 kHz left, 1 kHz right.

5.2 Service Modes

Service Default mode (SDM) and Service Alignment Mode
(SAM) offers 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 readout for all chassis.
Minimum requirements for ComPair: a Pentium processor, a
Windows OS, and a CD-ROM drive (see also paragraph
"ComPair").

5.2.1 Service Default Mode (SDM)

– Hotel / hospital mode.
– Auto shut off (when no “IDENT” video signal is

received for 15 minutes).
– Skipping of non-favorite presets / channels.
– Auto-storage of personal presets.
– Auto user menu time-out.
– Auto Volume Levelling (AVL).

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 "Service" jumpers on the TV board during cold start
and apply mains (see Figure "Service jumpers"). 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.

5.3 Service Tools

5.3.1 ComPair

Introduction

ComPair (Computer Aided Repair) is a Service tool for Philips
Consumer Electronics products. and offers the following:

1. ComPair helps you 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. You do not
have to know anything about I2C or UART commands
yourself, 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 upload possibilities.

Specifications

ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The (new) 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.

Note: If you encounter any problems, contact your local
support desk

5.3.2 LVDS 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. Thus to determine if LVDS, RGB, and sync
signals are okay.

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.

How to Connect

Connections are explained in the user manual, which is packed
with the tool.

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.

How to Order

3122 785 90671.

• LVDS tool Service Manual:
3122 785 00810.

• LVDS cable 31p/FI -> 31p/FI (standard with tool):
3122 785 90662.

5.4 Error Codes

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.

5.4.1 How 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.

5.4.2 How 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 activate SAM, press the following key sequence on

the remote control transmitter: “062596” directly
followed by the OSD/STATUS button (do not allow the
display to time out between entries while keying the
sequence).

– Make sure the menu item CLEAR is highlighted. 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.

Service Modes, Error Codes, and Fault Finding

EN 15LC4.8L LA 5.

5.4.3 Error 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).

5.5 The 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 RC 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.

5.6 Fault 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.

5.6.1 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 the NVM settings 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.

Service Modes, Error Codes, and Fault Finding

5.6.2 Load Default NVM Values

It is possible to download default values automatically into the
NVM in case a blank NVM is placed or when the NVM first 20
address contents are "FF". After the default values are
downloaded, it is possible to start-up and to start aligning the
TV set. To initiate a forced default download the following
action has to be performed:

1. Switch “off” the TV set with the mains cord disconnected
from the wall outlet (it does not matter if this is from
"Standby" or "Off" situation).

2. Short-circuit the SDM jumpers on the SSB (keep short
circuited).

3. Press “P+” or “CH+” on the local keyboard (and keep it
pressed).

4. Reconnect the mains supply to the wall outlet.

5. Release the “P+” or “CH+” when the set is “on” or blue LED
is blinking.

When the downloading has completed successfully, the set
should be into Standby, i.e. red LED on.

Alternative method (1):

1. Go to SAM.

2. Select NVM Editor.

3. Set ADR (address) to 0001 (dec, 4 digit).

4. Change the VAL (value) to 170 (dec, 3 digit).

5. Store the value (via CURSOR RIGHT).

6. Do a “hard reset” to make sure new default values took
place.

Alternative method (2):

It is also 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 NVM (or with a defective/no NVM), 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.

5.6.3 Tuner and IF

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 faultfinding 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. In Crystal Clear models, which
do not have an ADC and Columbus, the RGB path (analogue
input of scaler) is used for both video and teletext.

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.

5.6.5 Power Supply

In case the power supply does not work, check (apart from the
obvious fuse-check) if the oscillators in IC7001 (in TV sets with
37 inch screens) or in IC7001 and IC7U01 (in TV sets with 42
inch screens) are working. If not, replace the ICs.

No Picture in RF Mode, but there is a Noise Raster

1. Check whether picture is present in AV. If not, go to Video
processing troubleshooting section.

2. If picture is present, check if the Option settings are correct.

3. If correct, check if all the supply voltages are present (3.3/
5/8/12/33 V).

4. Check if the I

5. Manually store a known channel and check if there is IF
output at Tuner pin 11.

6. Check the tuning DC voltage at pin 2 of the Tuner. The DC
voltage should vary according to the frequency/channel
being chosen.

7. If the tuning voltage is OK, check the tuner output, pin 11.

8. If it has no output, the Tuner may have a defect. Change
the Tuner.

Required System is not Selected Correctly

Check whether a Service jumper (#4204 and 4205, 0805 size)
is present (diagram B2, location C9). If yes, remove it.

5.6.4 Video Processing

No Power

1. Check +12 V and 3V3 at position 1J02.

2. If no supply, check the connector 1J02.

3. If it is correct, check the Power Supply board.

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.

2

C lines are working correctly (3.3 V).
