2.1Safety Instructions for Repairs
Safety regulations require that during a repair:
•Due to the "hot" parts of this chassis, the set must be
connected to the AC power via an isolation transformer.
•Safety components, indicated by the symbol h, should be
replaced by components identical to the original ones.
•When replacing the CRT, safety goggles must be worn.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay particular attention to the
following points:
•General repair instruction: as a strict precaution, we advise
you to resolder the solder connections through which the
horizontal deflection current is flowing, in particular:
– all pins of the line output transformer (LOT)
– fly-back capacitor(s)
– S-correction capacitor(s)
– line output transistor
– pins of the connector with wires to the deflection coil
– other components through which the deflection current
flows.
Note: This resoldering 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 AC power cord for external
damage.
•Check the strain relief of the 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 AC plug
and the secondary side (only for sets that have an isolated
power supply). Do this as follows:
1. Unplug the AC power cord and connect a wire between
the two pins of the AC plug.
2. Turn on the main power switch (keep the AC power
cord unplugged!).
3. Measure the resistance value between the pins of the
AC plug and the metal shielding of the tuner or the
aerial connection of the set. The reading should be
between 4.5 MOhm and 12 MOhm.
4. Switch the TV "off" and remove the wire between the
two pins of the AC plug.
•Check the cabinet for defects, to prevent the possibility of
the customer touching any internal parts.
2.2Maintenance Instructions
It is recommended to have a maintenance inspection carried
out by qualified service personnel. The interval depends on the
usage conditions:
•When the set is used under normal circumstances, for
example in a living room, the recommended interval is
three to five years.
•When the set is used 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.
2.3Warnings
•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 Vdc). Discharge until the meter
reading is 0 V (after approx. 30 s).

•All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD w). Careless handling
during repair can reduce life drastically. When repairing,
make sure that 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.
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. Adjustment of this unit during repair is therefore not
recommended.
•Be careful during measurements in the high voltage
section and on the picture tube.
•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.
2.4Notes
2.4.1General
•Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the area of circuitry being tested.
•The voltages and waveforms shown in the diagrams are
indicative. Measure them in the Service Default Mode (see
“Service Modes, Error Codes, and Faultfinding” section)
with a color bar signal and stereo sound (L: 3 kHz, R: 1 kHz
unless stated otherwise) and picture carrier at 61.25 MHz
(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.
140501
Page 4
EN 4TE1.1E2.
•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 completely interchangeable per position
with the semiconductors in the unit, irrespective of the type
indication on these semiconductors.
2.4.2Schematic 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 expressed in Micro-Farads (µ =
-6
x10
), Nano-Farads (n = x10-9), or Pico-Farads (p = x10
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.
Safety & Maintenance Instructions, Warnings, and Notes
-
2.4.3Practical 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.
•Before powering up the TV set with the back cover off
(or on a test fixture), attach a clip lead to the CRT DAG
ground and to a screwdriver blade that has a well insulated
handle. After the TV is powered on and high voltage has
developed, probe the anode lead with the blade, starting at
the case of the High Voltage Transformer (flyback - IFT).
Move the blade to within two inches of the connector of the
CRT. If there is an arc, you found it the easy way, without getting a shock! If there is an arc to the
screwdriver blade, replace the part which is causing the
problem; the High Voltage Transformer or the lead (if it is
removable).

5.2ComPair Mode
5.2.1 Introduction
ComPair (Computer Aided Repair) is a service tool for Philips
Consumer Electronics products. ComPair is a further
development on the European DST (Dealer Service Tool),
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
2
C level) and

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.
5.2.2Specifications
Service Modes, Error Codes, and Fault Finding
EN 9TE1.1E5.
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.
The ComPair interface box and the TV communicate via a bidirectional service cable via the service connector.
The ComPair faultfinding program is able to determine the
problem of the defective TV set. ComPair can gather diagnostic
information in two ways:
•Automatic (by communication with the TV set): ComPair
can automatically read out the contents of the entire error
buffer. Diagnosis is done on I2C level. ComPair can send
and receive commands to the micro controller of the TV
set, and so can access the I2C bus of the TV set. In this
way, it is possible for ComPair to communicate (read and
write) to devices on the I2C busses of the TV set.
•Manually (by asking questions to you): Automatic
diagnosis is only possible if the micro controller of the TV
set is working correctly and only to a certain extend. 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
F7 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:
•Emulation of the (European) 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 C2228
(Schematic/Panel). Click on the 'Panel' hyperlink to
automatically show the PWB with a highlighted capacitor
C2228. Click on the 'Schematic' hyperlink to automatically
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 connector at the rear
side of the TV (situated just below the tuner input, see also
chapter 4).
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.

•Switch the TV in AV mode by pressing the AV button on the
remote control unit (minimum beam current condition).
•Adjust the VAP1 potentiometer until you measure 110Vdc
for 14” or 115 Vdc for 20” on the cathode of diode DP08.
8.2Software Alignments/Settings
Enter the Service Mode (see chapter 5). The Service Mode
menu will now appear on the screen.
The first screen that is displayed is of the IF adjustment. With
the CURSUR DOWN key the next menu item will be displayed.
The value can be changed with the LEFT/RIGHT CURSOR
keys.
8.2.1Adjustments
IF: You can select the following IF frequencies: 38.9, 38.0, 58.8
and 45.8 MHz

the G2 can be adjusted. When this item is selected information
about the G2 is displayed (INCR, OK, DECR). Turn the G2
potentiometer on the LOT until the screen displays “OK”.
“INCR” means the G2 must be increased and “DECR” means
the G2 must be decreased.
VSH: Vertical Shift. Default value is 41.
Connect a pattern generator to the TV and select a colour bar.
Set the contrast to 70%, brightness in the middle and the colour
saturation in the middle. Enter the service menu as described
in chapter 5 and perform the video adjustments BLR, BLG,
