Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

Index of this chapter:

2.1 Safety Instructions

2.2 Maintenance Instructions

2.3 Warnings

2.4 Notes

2.1 Safety Instructions

Safety regulations require that during a repair:

• Due to the chassis concept, a very large part of the circuitry
(incl. deflection) is 'hot'. Therefore, connect the set to the
mains via an isolation transformer.

• 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.

• Wear safety goggles when you replace the CRT.

Safety regulations require that after a repair, you must return
the set in its original condition. Pay, in particular, attention to
the following points:

• General repair instruction: as a strict precaution, we advise
you to re-solder the solder connections through which the
horizontal deflection current is flowing. In particular this is
valid for the:

1. Pins of the line output transformer (LOT).

2. Fly-back capacitor(s).

3. S-correction capacitor(s).

4. Line output transistor.

5. Pins of the connector with wires to the deflection coil.

6. Other components through which the deflection current

flows.
Note: This re-soldering is advised to prevent bad connections
due to metal fatigue in solder connections, and is therefore only
necessary for television sets more than two years old.

• Route the wire trees and EHT cable correctly and secure

them with the mounted cable clamps.

• Check the insulation of the mains cord for external

damage.

• Check the strain relief of the mains cord for proper function,

to prevent the cord from touching the CRT, hot
components, or heat sinks.

• Check the electrical DC resistance between the mains plug

and the secondary side (only for sets that have an isolated
power supply). Do this as follows:

1. Unplug the mains cord and connect a wire between the
two pins of the mains plug.

2. Turn on the main power switch (keep the mains cord
unplugged!).

3. Measure the resistance value between the pins of the
mains plug and the metal shielding of the tuner or the
aerial connection of the set. The reading should be
between 4.5 MΩ and 12 MΩ.

4. Switch the TV 'off' and remove the wire between the
two pins of the mains plug.

• Check the cabinet for defects, to prevent the possibility of
the customer touching any internal parts.

1. Perform the 'general repair instruction' noted above.

2. Clean the power supply and deflection circuitry on the
chassis.

3. Clean the picture tube panel and the neck of the picture
tube.

2.3 Warnings

• In order to prevent damage to ICs and transistors, avoid all
high voltage flashovers. In order to prevent damage to the
picture tube, use the method shown in Fig. 2-1, to
discharge the picture tube. Use a high voltage probe and a
multi-meter (position V_dc). Discharge until the meter
reading is 0 V (after approx. 30 s).

V

Figure 2-1 Discharge picture tube

• 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 potential. Available ESD
protection equipment:
– Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable and ground cable)
4822 310 10671.

– Wristband tester 4822 344 13999.

• Together with the deflection unit and any multi-pole unit,
flat square picture tubes form an integrated unit. The
deflection and the multi-pole units are set optimally at the
factory. We do not recommend adjusting this unit during
repair.

• Be careful during measurements in the high voltage
section and on the picture tube.

• Never replace modules or other components while the unit
is '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.

2.2 Maintenance Instructions

We recommend a maintenance inspection carried out by
qualified service personnel. The interval depends on the usage
conditions:

• When a customer uses the set under normal
circumstances, for example in a living room, the
recommended interval is three to five years.

• When a customer uses the set in an environment with
higher dust, grease, or moisture levels, for example in a
kitchen, the recommended interval is one year.

• The maintenance inspection includes the following actions:

2.4.1 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).

Safety Instructions, Warnings, and Notes

EN 5L04.6HU CA 2.

• 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 standby (F). These values are
indicated by means of the appropriate symbols.

• The picture tube panel has printed spark gaps. Each spark
gap is connected between an electrode of the picture tube
and the Aquadag coating.

• 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.

2.4.2 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 expressed in micro-farads (µ= x
10^-6), nano-farads (n= x 10^-9), or pico-farads (p= x 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 in the Electrical
Replacement Parts List. Therefore, always check this list
when there is any doubt.

2.4.3 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).

Figure 2-2 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.

E_06532_024.eps

230205

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.

• Use only original spare-parts listed in the Service-Manuals.
Not listed standard material (commodities) has to be
purchased at external companies.

• 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).

2.4.4 Alternative BOM identification

In September 2003, Philips CE introduced a change in the way
the serial number (or production number, see Figure 2-2) 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.

P

b

Figure 2-3 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

2.4.5 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.

5.7 Fault Finding and Repair Tips

5.1 Test Points

This chassis is equipped with test points in the service printing.
In the schematics test points are identified with a rectangle box
around Fxxx or Ixxx. These test points are specifically
mentioned in the “Test Point Overview” as “half moons” with a
dot in the center.

Perform measurements under the following conditions:

• Television set in Service Default Alignment Mode.

• Video input: Color bar signal.

• Audio input: 3 kHz left channel, 1 kHz right channel.

5.2 Service Modes

Service Default Alignment Mode (SDAM) offers several
features for the service technician, while the Customer Service
Mode (CSM) is used for communication between the call
center and the customer. For the TV setup main menu, please
refer to the DFU.

This chassis also offers the option of using ComPair, a
hardware interface between a computer and the TV chassis. It
offers the abilities 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").

• Software version.

• Option settings.

• Error buffer reading and erasing.

• Software alignments.

How to Enter SDAM

To enter SDAM, use one of the following methods:

• Switch the optional RC2573GR remote controll to Setup
mode, and press the following key sequence on the remote
control transmitter: “062596" directly followed by the
M(enu) button (do not allow the display to time out between
entries while keying the sequence).

• Or via ComPair.

• Or Short circuit the SDAM jumper on the mono carrier (see
Chapter 7: Layout Mono Carrier: Top side, item 9252 in cel
C5) and apply AC power. Then press the power button
(remove the short circuit after start-up).

Caution: Entering SDAM by short-circuiting the SDAM jumper
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 lead to damaging the set.

After entering SDAM, the following screen is visible, with “S” in
the upper right corner of the screen to indicate that the
television is in Service Default Alignment Mode.

5.2.2 Customer Service Mode (CSM)

Purpose

The Customer Service Mode shows error codes and
information on the TV’s operation settings. The call center can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set. This helps the call center 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.

How to Enter

To enter CSM, switch the optional RC2573GR remote controll
to Setup mode, and press its RECALL button.

Upon entering the Customer Service Mode, the following
screen will appear:

5.3.1 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:

• 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.

• 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.

• 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

2

C level) and

2

C commands

EN 12 L04.6HU CA5.

Service Modes, Error Codes, and Fault Finding

the Force/SearchMan electronic manual of the defective
chassis, schematics and PWBs are only a mouse click
away.

5.3.2 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

2

C/UART bus of the television.

2

C/UART commands to
the microcontroller 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 microcontroller 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.

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 enter 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 AC power from the
television set, the error buffer is not reset.

This is described in the chassis fault finding database in
ComPair.

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).

Note: For all error codes the following applies: error codes are

TV set.

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:

• When all the error-codes are displayed, the sequence
finishes with a LED blink of 1.5 seconds,

• The sequence starts again.

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 at 12 short blinks.

5.6 Protections

If a fault situation is detected, an error code will be generated;
and, if necessary, the television set will go into protection
mode. Blinking of the red LED at a frequency of 3 Hz indicates
the protection mode. In some error cases, the microprocessor
does not put the set in protection mode. The error codes of the
error buffer and the blinking LED procedure can be read via the
Service Default Menu (SDM), or via ComPair.

To get a quick diagnosis the chassis has three service modes
implemented:

• The (Digital) Customer Service Mode ((D)CSM).

• The Service Default Mode (SDM).

• The Service Alignment Mode (SAM).

For a detailed mode description, see the relevant sections.

5.7 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.

5.7.1 NVM 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. In the next table, some default NVM values are given.

5.7.7 Controller

Below are some guidelines for troubleshooting of the Micro
Controller function. Normally Micro Controller should be
checked when there is a problem of startup.

1. Check that both +3.3 V_dc and +1.8 V_dc are present.

2. Check that crystal oscillator is working.

3. Check that Power Good signal is at “high” logic, normal
operation.

4. Check that Hercules is not in standby mode. Pin 15 of
Hercules should be 0 V_dc.

5. Make sure H-drive pulse is there. This can be checked at
resistor R3239. If H-drive does not exist, remove resistor
R3239 to check if there is loading.

Note: When the set shuts down after a few second after power
“on”, the main cause is that Vg2 not aligned properly, try
adjusting Vg2 during the few seconds of power “on”.

5.7.8 Video Processing

No Picture

When “no picture in RF”, first check if the microprocessor is
functioning ok in section “Controller”. If that is ok, follow the
next steps.
When “no picture in AV”, first check if the video source
selection is functioning ok in section “Source Selection”. If that
is ok, follow the next steps.

1. Check that normal operating conditions are met.

2. Check that there is video signal at pin 81. If no video,
demodulator part of the Hercules is faulty, replace with new
Hercules.

3. If video signal is available at pin 81, check pin 56, 57, and
58 for the RGB signal.

4. If signal is not available, try checking the BRIGHTNESS
and/or CONTRAST control, and make sure it is not at zero.

5. If still with the correct settings and no video is available,
proceed to the CRT/RGB amplifier diagram.

For sets with Scavem, and Scavem does not work, follow steps
below:

1. Check Scavem coil connector (position is 1361) if
connected; if not, connect it.

2. If connected, check NVM “bit storage” byte 1 bit 7; if it is not
“1”, set it to “1”.

3. If it is “1”, then check the data of the NVM addresses as in
table “Default NVM values“ (addresses 140, 141, and 142).
If the data is not correct, then set these addresses to the
table values.

4. If it still not works, track Scavem output from pin64 of
Hercules to CRT panel.
