Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
2.1Safety Instructions
Safety regulations require that 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 which
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 avoid touching of any
inner parts by the customer.
2.2Warnings
•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).
– 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.
2.3Notes
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 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 standby (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.

•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

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
-9
), or pico-farads (p= 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 Electrical
Replacement Parts List. Therefore, always check this list
when there is any doubt.

2.3.3 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, it is essential when
removing an (LF)BGA, 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 chance 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 shown to result in
problems during re-soldering.
please contact the manufacturer of your soldering
equipment.
•Use only adequate solder tools applicable for lead-free
soldering tin.
•Adjust your solder tool so that a temperature around 217 220 deg. C is reached at the solder joint.
•Do not mix lead-free soldering tin with leaded soldering tin;
this will lead to unreliable solder joints!
•Use only original spare parts listed in this manual. These
are lead-free parts!
•On the website www.atyourservice.ce.philips.com
subscription, not available for all regions) you can find
more information on:
– Aspects of lead-free technology.
– BGA (de-)soldering, heating-profiles of BGAs used in
Philips sets, and others.
2.3.5Practical 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 - 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.
(needs
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.
To reflow the solder, apply a temperature profile according to
the IC data sheet. So as not to damage neighbouring
components, it may be necessary to reduce some
temperatures and times.

2.3.4 Lead Free Solder
Some PWBs in this chassis are “lead-free prepared”. This is
indicated on the PWB by the PHILIPS lead-free logo (either by
a service-printing or by a sticker). It does not mean that leadfree solder is actually used!

Due to this fact, 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,

5.4ComPair
5.4.1Introduction
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
the SearchMan electronic manual of the defective chassis,
schematics and PWBs are only a mouse click away.
5.4.2Specifications
ComPair consists of a Windows based faultfinding 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.
For this chassis, the ComPair interface box and the TV
communicate via a bi-directional service cable via the service
connector.
The ComPair faultfinding 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 I
2
the I
C bus of the television. ComPair can send and
receive I
2
C 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 I
of the TV-set.
•Manually (by asking questions to you): Automatic
diagnosis is only possible if the micro controller of the
2
C level. ComPair can access
2
C level) and
2
C commands

Service Modes, Error Codes, and Fault Finding
television is working correctly and only to a certain extends.
When this is not the case, ComPair will guide you through
the faultfinding 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 faultfinding 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
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 “I
2
C”) and the ComPair connector at the rear
side of the TV.
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.

5.5Error 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 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.
5.5.2 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.
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).

5.6The 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:
•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.
5.7Protections
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 mode description, see the relevant sections.

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 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”.
5.8.7 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 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 pin64 of
HERCULES to CRT panel.

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.
Note: If there is audio signal at Hercules output and no audio
at loudspeaker, proceed to Audio Amplifier troubleshooting
methods.
5.8.9 Audio Amplifier
No RF as well as 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
