2.4 Notes

2.1 Safety 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 re-solder 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 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 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 MΩ and 12 MΩ.

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.

2.2 Maintenance 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.

2.3 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 VDC). Discharge until the meter
reading is 0 V (after approx. 30 s).

Figure 2-1

• 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. 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. 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.

2.4 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
semiconductors in the unit, irrespective of the type
indication on these semiconductors.

Safety Instructions, Warnings, and Notes

EN 5L01.2A AB 2.

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, 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.

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.

Philips CE is going to produce lead-free sets (PBF) from

1.1.2005 onwards.

),

).

Figure 2-2 Lead-free logo

This sign normally has a diameter of 6 mm, but if there is less
space on a board also 3 mm is possible.

Regardless of this logo (is not always present), one must treat
all sets from this date onwards according to the following rules.

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 at least a solder-tip temperature of 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 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 rise 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 not to avoid, clean carefully 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
short 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.

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

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.

Service Modes, Error Codes, and Fault Finding

– Activate the selected submenu.

• When you press the MENU button twice, the set will switch
to the normal user menus (with the SAM mode still active
in the background). To return to the SAM menu press the
OSD / STATUS button [ i+ ].

• When you press the MENU key in a submenu, you will
return to the previous menu.

How to exit

Switch the set to STANDBY by pressing the power button on
the remote control (if you switch the set 'off' by removing the AC
power, the set will return in SAM when AC power is re-applied).
The error buffer is not cleared.

5.2.3 Customer Service Mode (CSM)

Purpose

When a customer is having problems with his TV-set, he can
call his dealer. The service technician can than ask the
customer to activate the CSM, in order to identify the status of
the set. Now, the service technician can judge the severness of
the complaint. In a lot of cases he can advise the customer how
to solve the problem, or he can decide if it is necessary to visit
the customer.
The CSM is a read only mode, therefore modifications in this
mode are not possible.

How to enter

The CSM will be turned on after pressing the MUTE key on the
remote control transmitter and any of the control buttons on the
TV for at least 4 seconds simultaneously. This activation only
works if there is no menu on the screen.

After switching ON the Customer Service Mode, the following
screen will appear:

10. Value indicates parameter levels at CSM entry (only for
stereo sets). TR= TREBLE, BS= BASS

How to exit

Use one of the following methods:

• After you press ‘any’ key of the remote control transmitter
with exception of the CHANNEL and VOLUME keys.

• After you switch-off the TV set with the AC power switch.

5.4 ComPair

receive I
television. In this way, it is possible for ComPair to
communicate (read and write) to devices on the I

2

C commands to the micro controller of the

2

C busses

of the TV-set.

• 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 faultfinding tree by asking you questions (e.g. Does the
screen gives 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 (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 C2568
(Schematic/Panel) at the Monocarrier.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.

5.4.1 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
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 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.
In case of the L01 chassis, the ComPair interface box and the
TV communicate via a bi-directional service cable via the
service connector (located on the Main panel, see also figure
8-1 suffix D).

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

2

C level. ComPair can access

2

C level) and

2

C commands

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 AC power adapter to the supply connector
(marked with ‘POWER 9V DC’) on the ComPair interface.

4. Switch the ComPair interface OFF.

5. Switch the television set OFF (remove the AC power).

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 on the

mono carrier (see figure 8-1 suffix D).

7. Plug the AC power adapter in the AC power outlet and
switch on the interface. 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.

• ComPair interface cable: 3122 785 90004

5.5 Error Buffer

The error code buffer contains all detected errors 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 written at the left side and all other errors shift one
position to the right.

5.5.1 How to Read the Error Buffer

Use one of the following methods:

• On screen via the SAM (only 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 first detected and

error code 9 is the last detected (newest) error

• Via the blinking LED procedure (when you have no
picture). See next paragraph.

•Via ComPair.

5.5.2 How to Clear the Error Buffer

The error code buffer is cleared in the following cases:

• By activation of the CLEAR command in the SAM menu:

• When you exit SDM / SAM with the STANDBY command
on the remote control (when leaving SDM / SAM, by
disconnecting the set from AC power, the error buffer is not
reset).

• When you transmit the command DIAGNOSE-99-OK with
ComPair.

• If the content of the error buffer has not changed for 50
hours, it resets automatically.

5.5.3 Error Codes

In case of non-intermittent faults, clear the error buffer before
you begin the repair. These to ensure 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
code and not the actual cause (e.g., a fault in the protection
detection circuitry can also lead to a protection).

5.6 The Blinking LED Procedure

Via 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.
Error-codes ≥ 10 are shown as follows:
– a long blink of 750 ms (which is an indication of the decimal

digit),
– a pause of 1.5 s,
– n short blinks (n = 1 - 9),
– when all the error-codes are displayed, the sequence

finishes with a LED blink of 3 s,
– the sequence starts again.

Example of error buffer: 12 9 6 0 0
After entering SDM:
– 1 long blink of 750 ms followed by a pause of 1.5 s,
– 2 short blinks followed by a pause of 3 s,
– 9 short blinks followed by a pause of 3 s,
– 6 short blinks followed by a pause of 3 s,
– 1 long blink of 3 s to finish the sequence,
– the sequence starts again.

5.7 Protections

time, measure the ‘+8V’. If this voltage is missing, check
transistor TS7480.

• Set is non-stop in hiccup mode Set is in over current

mode; check the secondary sensing (opto coupler 7515)
and the ‘MainSupply’ voltage. Signal ‘Stdby_con’ must be
logic low under normal operation conditions and goes to
high (3.3 V) under standby and fault conditions.

• Set turns on, but without picture and sound The screen

shows snow, but OSD and other menus are okay. Blinking
LED procedure indicates error 11, so problem is expected
in the tuner (pos. 1000). Check presence of supply
voltages. As ‘Vlotaux+5V’ at pin 5 and 7 are okay,
‘VT_supply’ at pin 9 is missing. Conclusion: resistor 3460
is defective.

• Set turns on, but with a half screen at the bottom.
Sound is okay Blinking LED (set in SDM mode) indicates
error 3. Check ‘Vlotaux+13V’ and ‘+50V’. If they are okay,
problem is expected in the vertical amplifier IC7471.
Measure with a scope the waveform on pin 17 of the UOC.
Measure also at pin 1 of IC7471. If here the signal is
missing, a defective resistor R3244 causes the problem.

If a fault situation is detected an error code will be generated
and if necessary, the set will be put in the 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 the protection mode. The error codes of
the error buffer can be read via the service menu (SAM), the
blinking LED procedure or via ComPair. The DST diagnose
functionality will force the set into the Service-standby, which is
similar to the usual standby mode, however the microprocessor
has to remain in normal operation completely.

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

• The Customer Service Mode (CSM).

• The Service Default Mode (SDM). Start-up of the set in a
predefined way.

• The Service Alignment Mode (SAM). Adjustment of the set
via a menu and with the help of test patterns.

See for a detailed description Chapter 9 paragraphs Deflection
and Power Supply.

5.8 Repair Tips

Below some failure symptoms are given, followed by a repair
tip.

• Set is dead and makes hiccuping sound ‘MainSupply’ is
available. Hiccuping stops when de-soldering L5561,
meaning that problem is in the ‘MainSupply’ line. No output
voltages at LOT, no horizontal deflection. Reason: line
transistor TS7460 is defective.

• Set is dead, and makes no sound Check power supply
IC7520. Result: voltage at pins 1, 3, 4, 5 and 6 are about
180 V and pin 8 is 0 V. The reason why the voltage on
these pins is so high is because the output driver (pin 6)
has an open load. That is why MOSFET TS7521 is not able
to switch. Reason: feedback resistor 3523 is defective.
Caution: be careful measuring on the gate of TS7521;
circuitry is very high ohmic and can easily be damaged!
(first connect measuring equipment to ground, then to the
gate).

• Set is in hiccup mode and shuts down after 8 s. Blinking
LED (set in SDM mode) indicates error 5. As it is unlikely
that µP ‘POR’ and ‘+8V protection’ happen at the same
