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 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.

• Wear safety goggles when you replace the CRT.

Safety regulations require that after a repair, the set must be
returned 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 flows. 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/AC Power lead for
external damage.

• Check the strain relief of the Mains/AC Power 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/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 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:

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 figure “Discharge
picture tube”, to discharge the picture tube. Use a high
voltage probe and a multi-meter (position V
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 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 prevents circuits
from becoming unstable.

2.4 Notes

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 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

“Dolby”, “Pro Logic” and the “double-D symbol”, are
trademarks of Dolby Laboratories.

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 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.

2.4.3 Rework 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.

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.

2.4.4 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).

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
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
clean 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.

• 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.

EN 6 L04E AE2.

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.

2.4.5 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.

Safety Instructions, Warnings, and Notes

2.4.6 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.

5.4 ComPair

Note:

Make sure that both the ComPair connector and the UART
connector are shielded off with a piece of insulating tape after
repair for ESD reasons. Place this tape over the holes in the
rear cover of the set.

5.4.1 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 I2C level)
and is therefore capable of accurately indicating problem
areas. You do not have to know anything about I2C
commands 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
the SearchMan electronic manual of the defective chassis,
schematics and PWBs are only a mouse click away.

5.4.2 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 RS232 cable.
In this chassis, the ComPair interface box and the TV
communicate via a bi-directional service cable via the service
connector.

The ComPair fault finding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:

• Automatic (by communication with the television):
ComPair can automatically read out the contents of the
entire error buffer. Diagnosis is done on I2C level. ComPair
can access the I2C bus of the television. ComPair can
send and receive I2C commands to the micro controller of
the television. In this way, it is possible for ComPair to
communicate (read and write) to devices on the I2C
busses of the TV-set.

EN 14 L04E AE5.

Service Modes, Error Codes, and Fault Finding

• 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 extend.
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 waveform 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.

Beside fault finding, ComPair provides some additional
features like:

• Up- or downloading of pre-sets.

• Managing of pre-set lists.

• Emulation of the Dealer Service Tool (DST).

• If both ComPair and SearchMan (Electronic Service
Manual) are installed, all the schematics and the PWBs of
the set are available by clicking on the appropriate
hyperlink. Example: Measure the DC-voltage on capacitor
C2568 (Schematic/Panel) at the Mono-carrier.
– Click on the 'Panel' hyperlink to automatically show the

PWB with a highlighted capacitor C2568.

– Click on the 'Schematic' hyperlink to automatically

show the position of the highlighted capacitor.

5.4.3 How to Connect ComPair

1. First, install the ComPair Browser software (see the Quick
Reference Card for installation instructions).

2. Connect the RS232 interface cable between a free serial
(COM) port of your PC and the PC connector (marked with
'PC') of the ComPair interface.

3. Connect the mains adapter to the supply connector
(marked with 'POWER 9V DC') of the ComPair interface.

4. Switch the ComPair interface “OFF”.

5. Switch the television set “OFF” with the mains switch.

6. Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface
(marked with 'I2C') and the ComPair (or Service) connector
at the rear side of the TV (for its location see figure 8-1 in
chapter “Alignments”).

7. Plug the mains adapter in a mains outlet, and switch the
interface “ON”. The green and red LEDs light up together.
The red LED extinguishes after approx. 1 second while the
green LED remains lit.

8. Start the ComPair program and read the 'Introduction'
chapter.

5.5 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.

5.5.1 How to Read the Error Buffer

You can read the error buffer in 3 ways:

• On screen via the SDAM (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.

5.5.2 How to Clear the Error Buffer

The error code buffer is cleared in the following cases:

• By using the CLEAR command in the SDAM menu:
– To enter SAM, press the following key sequence on the

remote control transmitter: '062596' directly followed
by the “OSD" icon 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.

5.5.3 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).

5.6 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 LED will blink the contents of the
error-buffer:

• When all the error-codes are displayed, the sequence
finishes with an 'ON' 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 'ON' 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 'ON' blink of 1.5 seconds to finish the sequence,

• The sequence starts again at 12 short blinks.

5.7 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 Customer Service Mode (CSM).

• The Service Default Mode (SDM).

• The Service Alignment Mode (SAM).

For a detailed description, see the "Customer Service Mode,
Service Default mode" and "Service Alignment Mode" sections.

5.8 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.

5.8.1 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

5.8.6 Controller

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

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

2. Check that crystal oscillator is working.

Service Modes, Error Codes, and Fault Finding

EN 19L04E AE 5.

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”.

5.8.7 Video Processing

No Picture

When “no picture in RF”, first check if the microprocessor is
functioning o.k. in section “Controller”. If that is o.k., follow the
next steps.
When “no picture in AV”, first check if the video source
selection is functioning o.k. in section “Source Selection”. If that
is o.k., 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 TDA9178, follow steps below:

1. Put Option Byte 2 bit 4 to “0”; if video signal is not available,
then check fault finding section “Controller”, Section
“Source Selection”, and steps above.

2. If video is available but not correct, put Option Byte 2 bit 4
to “1”, then check if LTI panel is present. If not, put LTI
panel in the main chassis (connector 1221).

3. If LTI panel is in main chassis, check cable between LTI
panel and main chassis (position is 1206). If it is
connected, then the LTI panel is faulty, replace it.

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
the next table. If the data is not correct, then set these
addresses to diagram values.

4. If it still not works, track Scavem output from pin 64 of
HERCULES to CRT panel.

No RF audio for QSS/Inter-Carrier stereo sets.

1. Check pin 99 and 100 for SIF signal (for QSS) or pin 104
and 105 for video with SIF (for Inter-Carrier)

2. If signal is not present, check for the QSS/FMI bit settings.
Check also the NVM data.

3. If signals are present and still no audio, check the audio
supply voltage +8V are present.

4. If still no audio signal at Hercules output, Hercules is faulty.

No AV audio.

1. Check troubleshooting methods in section “Source
Selection”.

2. Check the output of the Hercules to see if there is signal
available. If no, check the normal operating condition and
also the NVM data.

3. If still no audio signal at Hercules output, Hercules is faulty.

If there is audio signal at Hercules output and no audio

Note:

at loudspeaker, proceed to Audio Amplifier troubleshooting

5.8.9 Audio Amplifier

No RF nor AV audio at the loudspeaker:

1. Check that the normal operation condition of the amplifier
is met.

2. If normal operation conditions are met, check the continuity
from Hercules output to input of the amplifier.

3. If continuity is there and still no audio, check speaker wire
connections. If still no audio, amplifier IC might be faulty.
