Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

2.1 Safety Instructions

Index of this chapter:

2.1 Safety Instructions

2.2 Maintenance Instructions

2.3 Warnings

2.4 Notes

Safety regulations require that during a repair:

• Due to the chassis concept, a very large part of the chassis

(including horizontal and vertical deflection) is 'hot.'
Connect the set to AC power via an isolation transformer.

• Safety components, indicated by the symbol h, must be

replaced with original PCEC components.

• 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 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:

1. All pins of the line output transformer (LOT.)

2. Flyback 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 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.) To do this:

1. Unplug the AC power cord and connect a wire between

the two pins of the AC plug.

2. Set the AC power switch to the “on” position (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.

• Check the cabinet for defects, to prevent the customer from
touching any inner parts of the television set.

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 multimeter
(position Vdc.) Discharge until the meter reading is 0 V
(after approx. 30s.)

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. When repairing,
make sure that you are connected with the same potential
as the mass of the set by a wristband with resistance. Also
keep components and tools at this potential.

• Available ESD protection equipment:
– Complete kit ESD3 (small table mat, 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.

CL96532156_040.eps

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.

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 area of circuitry being tested.

• The voltages and waveforms shown in the diagrams are
indicative. Measure them in the Service Default Mode 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.

Safety Instructions, Warnings, and Notes

EN 5EM1.1A AA 2.

• 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.

• DOLBY, the double D symbol and PRO LOGIC are
trademarks of Dolby Laboratories Licensing Corporation.
Manufactured under license from Dolby Laboratories
Licensing Corporation.

Figure 2-2 Dolby Pro Logic Symbol

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 =

-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.

2.4.3 Lead Free Solder

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

1.1.2005 onwards.

Lead-free sets will be indicated by the PHILIPS-lead-free logo
on the Printed Wiring Boards (PWB):

P

b

Figure 2-3 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.

In case of doubt wether 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 "Workshop information".
For additional questions please contact your local repair­helpdesk.

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.

2.4.4 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 - 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.

• Provide a situation with predefined settings in order to
retrieve the same measurement results as published in this
manual.

• Start the “blinking LED” sequence procedure.

• Have the possibility to override the 5V protection.

Specifications

• Tuning frequency: 475.25 MHz for PAL.

• Colour system: PAL B/G.

• All picture settings at 50% (brightness, color, picture).

• All sound settings at 50% except volume at 25% (bass,
treble, and balance at 50%, volume at 25%).

• All service-unfriendly modes (if present) are disabled, such
as:
– (sleep) timer,
– child/parental lock,
– blue mute,
– hotel/hospitality mode,
– auto switch-off (when no video signal is received for 15

minutes),
– skip/blank of non-favorite presets/channels,
– auto store of personal presets,
– auto user menu time-out.

How to enter SDM

Use one of the following methods:

• Press the following key sequence on the remote control
transmitter:

• 0-6-2-5-9-6-MENU Do not allow the display to time out
between entries while keying the sequence.
Note: It is possible that the main menu will appear when
entering SDM. To switch it off, push the ‘MENU’ button
again.

• Via ComPair (simulating the DST).

• Via short-circuiting the solder pads on the SSB (next to
connector 1304). Disconnect the set from the mains, short
circuit pads, then reconnect the set to the mains.

Caution: Entering SDM by short-circuiting the solder pads on
the SSB will override the 5V protection. This should only be
done for a short period. In case of SW protections (errors 1,2,4
and 8), the set will shut down in 15 seconds.

When doing this, the service technician must know what
he is doing, as it could lead to damaging the set.

After entering SDM, 'SDM' will appear at the upper right corner
of the screen for recognition.

How to navigate in SDM

When you press the 'MENU' button on the remote control
transmitter, the set toggles between the SDM and the normal
user menus (with the SDM mode still active in the background).

When you press the 'STATUS/EXIT' button on the remote
control transmitter, the set shows/hides the error buffer. To
prevent interference with oscilloscope measurements, it is
possible to hide the OSD.

How to exit SDM

Switch the set to STANDBY by pressing the ‘POWER’ button
on the remote control transmitter or press the 'POWER' switch
on the set.

5.2.2 Service Alignment Mode (SAM)

5.2.3 Customer Service Mode (CSM)

Purpose

When a customer is having problems with his TV set, the
service technician can ask the customer to activate the CSM,
in order to identify the status of the set. Now, the service
technician can judge the severity of the complaint. In many
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 are not
possible in this mode.

How to enter CSM

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.

Line 1:
HRS: Hexadecimal counter of operating hours. Example: 1B
(hex)= 0001 1011 (binary)= 27 (decimal).
Standby hours are not counted as operating hours.
Note: every time the set is turned on, the counter will advance
one hour.

SWID: Software identification of the main microprocessor (see
explanation of software version in the “Service Alignment
Mode” section).

Line 2:
Error code buffer (for more details see “Error buffer” section).
Displays the last 7 errors of the error code buffer.

Line 3:
Option bit setting controls the software and hardware
functionality. An option byte or option number represents 8 of
those bits. Each option number is displayed as a decimal
number between 0 and 255. The set may not work correctly

when an incorrect option code is set. See “Alignments” section
for more information on correct option settings.

Line 4:
Not valid in this set. No message here.

Line 5:

key on the remote control transmitter (except the 'channel +' or
'channel -' key) or turning off the TV set with the 'POWER'
button on the remote control transmitter or the television set.

5.3 Problems and Problem Solving Tips

5.3.1 Picture Problems

TV switches off or changes channel without any user action

The TV set switches off after 'TV SWITCHING OFF' was
displayed.
Auto standby switched the set off because:

• There was no signal identification signal for more than 15
minutes.

• There was no remote control transmitter signal received or
local key pressed for over 2 hours.

See “Alignments” section for a description of the options to
enable/disable auto standby (option SBNP).

Picture too dark or too bright

• Press the 'Smart Picture' button on the remote control
transmitter. If the picture improves, increase/decrease the
brightness value or increase/decrease the contrast value.

• If the picture is OK after entering Customer Service Mode,
increase/decrease the brightness value or increase/
decrease the contrast value.

following:

• no antenna signal or bad antenna signal; connect a proper
antenna signal

• antenna not connected; connect the antenna

• no broadcast on this channel.

• the tuner is faulty (in this case the 2: CODES line will
contain number 13 (Main Tuner 'A'); check the tuner and
replace/repair the tuner if necessary

Snowy picture and/or unstable picture

• A scrambled or decoded channel is being received.

Black and white picture

• Press the 'Smart Picture' button on the remote control
transmitter. If the picture improves, increase the color
value.

• If the picture is OK after entering Customer Service Mode,
increase the color value.

• Press the 'Smart Picture' button on the remote control
transmitter. If the picture improves, decrease the contrast
value.

• If the picture is OK after entering Customer Service Mode,
decrease the contrast value.

5.3.2 Sound Problems

No sound or sound too loud (after channel change/ switching on)

• If the volume is OK after entering Customer Service Mode,
increase/decrease the volume level.

the TV communicate via a bi-directional service cable via the
service connector at the rear side of the set.

The ComPair faultfinding program is able to detect and
diagnose problems occurring in the product. 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
can access the I
and receive I

2

C bus of the television. ComPair can send

2

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

2

C level. ComPair

2

C busses

of the television set.

• Manually (by asking questions to you): Automatic
diagnosis is only possible if the microprocessor of the
television is working correctly and only to a certain extent.
When this is not the case, ComPair will guide you through
the faultfinding tree by asking you questions (for example,
Does the screen give a picture? Click on the correct
answer: YES/NO) and showing you examples (for
example, Measure test point I7 and click on the waveform
you see on the oscilloscope). You can answer by clicking
on a link (for example, 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.

Besides fault finding, ComPair provides some additional
features like:

• Emulation of the Dealer Service Tool (DST).

• If both ComPair and SearchMan / Force (Electronic
Service Manual) are installed, all the schematics and the
CBAs 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 CBA with a highlighted capacitor C2568.

– Click on the “Schematic” hyperlink to automatically

show the electronic position of the highlighted
capacitor.

5.4 ComPair

5.4.1 Introduction

ComPair (Computer Aided Repair) is a service tool for Philips
Consumer Electronics products. ComPair is a further
development of the DST (special remote control transmitter for
Service), which allows faster and more accurate diagnostics.
ComPair has three big advantages:
ComPair helps you to quickly get an understanding how to
repair this chassis in a short time by systematically guiding you
through the repair procedures.
ComPair allows very detailed diagnostics (on I
therefore capable of accurately indicating problem areas. You
do not have to know anything about I
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/ EM1.1A
electronic service manual, schematics and CBAs 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 this chassis, the ComPair interface box and

5.5 Error Buffer

5.5.1 Introduction

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.

5.5.2 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 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' section.

•Via ComPair.

5.5.3 How to Clear the Error Buffer

Use one of the following methods to clear the error buffer:

• Activate the 'CLEAR ERRORS' command in the SAM
menu.

• Transmit the command 'DIAGNOSE-99-OK' with ComPair.

• If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.

5.5.4 Error Codes

If the set has non-intermittent faults, clear the error buffer
before starting repairs. This is to ensure that “old” error codes
are not 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 of the problem). For example,
a fault in the protection detection circuitry can also lead to a
protection.

Explanation of error codes:

Error 0

No errors

Error 1
‘FBX 3V3 protection’

This protection is activated when the PICNIC (pos. 7709 on
diagram B3) cannot communicate via I

2

C for a certain time.
This could mean that stabilizer 7009 (B7) or 7713 (B3) on SSB
(depending on the set) is defective. When there is a short circuit
to ground behind the stabilizer, 7009 or 7713 could become
very hot. For safety reasons, the set will switch to protection
mode.

Error 2

‘No Horizontal Flyback protection’
The HOP (pos. 7301 on diagram B4 detects the absence of an
HFB pulse (pin 3 of connector 1424 on LSP, diagram A3)). A
bit will be set in the HOP. After filtering by the software, the set
will switch to protection mode.

Error 4
‘+5V protection’

When the +5V protection is active, the set is switched to
protection mode and error code 4 is placed in the error buffer.
The LED will blink 4 times (repeatedly).
A 5V failure can cause a drop in the 5V supply output, resulting
in an undefined behavior of the set. Therefore, some I

2

C
devices (Tuner and MSP) connected to the 5V supply are
constantly monitored. When none of these devices responds to
the microprocessor for a prolonged time, the microprocessor
assumes that there is a failure in the 5V supply.
By starting up (by disconnecting/reconnecting the set from the
mains) the set while short-circuiting the SDM solder pads on
the SSB, the +5V protection will be overridden, and it will be
easier to determine the cause. The +5V protection will be
activated when these I

2

C devices fail (no I2C communication):
– Main Tuner (pos. 1200 on the LSP),
– MSP3452 sound processor (pos. 7651 on the SSB).

Service Modes, Error Codes, and Fault Finding

EN 15EM1.1A AA 5.

The following tips are useful to isolate the problem area, after
overriding the +5V protection. Determine whether:
– The MSP sound processor is loading the +5V; isolate 3650

and/or 4604 (see diagram B6).

– The main Tuner is loading the +5V source; isolate coil

5901.

Error 5
‘HOP POR error’

When the POR bit is not communicated during startup, the
processor will generate 'HOP POR not successful.'

Error 6
‘General I

2

C error’

This will occur in the following cases:
– SCL or SDA is shorted to ground.
– SCL is shorted to SDA.
– SDA or SCL connection at the microprocessor is open.

Error 7
‘Mains Dip error’ Hardware error; this error indicates

problems with the mains.

Error 9
‘TEDE9’ Tuner protection of the main tuner.

Error 10
‘NVM error’

Non Volatile Memory (EEPROM - pos. 7012) does not respond
to the microprocessor.

Error 11
‘NVM Identification error’

During the last startup, the NVM and the microprocessor did
not recognize each other (for example, one of them was
replaced, or the NVM memory has been changed/adapted or
lost), therefore the NVM was loaded with default values.

Error 12
‘Painter error’

Microprocessor (Painter - pos. 7001) internal RAM test failure.

Error 14
MSP error

Sound controller MSP34xx (pos. 7651) does not respond to the
microprocessor.

Error 22
Histogram IC error

Note: Error codes 1, 2, 4, and 7 are protection codes, and in
this case supplies of some circuits will be switched off. Also, in
protection, the LED will blink the number of times equivalent to
the most recent error code.

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 for fault
finding 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 750ms (which is an indication of the decimal

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

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

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

Note: If errors 1, 2, 4 or 7 occur, the LED always gives the most
recent error, even if the set is NOT in service mode.

5.7 Protections

5.7.1 General

This chassis has only one microprocessor (Painter) which
remains active during Standby. This is because power for the
microprocessor and the memories comes from the 3V3 supply,
which is derived from the 5V Standby circuitry. Therefore, in
both Power On and Standby mode the microprocessor is
connected to this power supply.

If a fault situation is detected, an error code will be generated,
and if necessary, the set will be put in the protection mode. The
protection mode is indicated by blinking of the LED (at a
frequency of 3Hz). 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 DST/ComPair.

To get a quick diagnosis, this chassis has 3 service modes
implemented:

• The Customer Service Mode (CSM).

• The Service Default Mode (SDM). Startup of the set in a

predefined way.

• The Service Alignment Mode (SAM). In this mode, items of

the set can be adjusted via a menu and with the help of test

patterns.

The “Protection Diagram” shows the structure of the protection
system. See diagram below.

Figure 5-2 Protection diagram

There are several types of protections:

2

•I

C related protections (for example, +5V supply check).

• HOP related protections (mainly for deflection items).

• Hardware errors which are not sensed by the Painter (for
example, BRIDGE_PROT)

2

I

C related protections

In normal operation, some registers of the I
will be refreshed every 200ms. During this sequence, the I
busses and the I
take place if the SDA and SCL are short-circuited to ground or
to each other. An I

2

C ICs will be checked. The I2C protection will

2

C error can also occur if the power supply

2

C controlled ICs

2

C

of the IC is missing (for example, FBX_PROT: error 1).

HOP related protections

Every 200ms, the status register of the HOP is read by the
Painter via I

2

C. If a protection signal is detected on one of the
inputs of the HOP, the relevant error bit in the HOP register is
set to “high.” If the error bit is still “high” after 1s, the Painter will
store the error code in the error buffer (NVM) and, depending
on the relevance of the error bit, the set may or may not go into
protection mode.

• HFB: Horizontal Flyback. If the horizontal flyback is not

present, then this is detected via the HOP (HFB_X­RAY_PROT). One status bit is set to “high.” The error code
is stored in the error buffer and the set will go into the
protection mode.

• Flash detection. From the EHT info, via D6303 and T7303,

a flash will stop the H-drive and line output stage
immediately. The FLS bit in the status register of the HOP
is set to “high.” As the duration of a flash is very short, the
FLS bit will be reset to “low” again after the flash refresh,
and the set will be started again via a slow start.

Hardware related protections

Due to the architecture (with “hot” deflection) there are two
protections that are “unknown” to the microprocessor, namely
the 'BRIDGE_PROT' (coming from the line stage) and the
'DEFL_PROT' protection (coming from the frame deflection
stage).
If one of these protections is triggered, the set is switched to
“Standby” mode. The Painter will now try to restart the set. If
this does not succeed after 5 times (after 30 - 60 seconds), the
Painter will generate error 2 (this error can have several

causes, such as repeating flashes, BRIDGE_PROT/Non VFB
leading to DEFL_PROT, or a serious AC power dip). The red
LED will start blinking.

5.8 General tips and repair tips

5.8.1 General

Notice that a very large part of the set (Large Signal Panel) is
“hot,” meaning the primary part of the Standby supply, the
whole Main supply (except for the secondary Audio supply),
and the complete deflection circuit are "hot."
Note: The deflection-coil is hot.

This set is not equipped with an IR transmitting LED. Instead,
a Service (ComPair) connector is implemented at the rear of
the set, which is directly accessible (it is not necessary to
remove the back cover to access the connector).
In addition to this, there is a blinking LED procedure to show the
contents of the error buffer.

The relay you hear during switching the set “on” (via the power
switch) is from the degaussing circuitry. So it is not used for
switching the supply as in the MG chassis.

When there is a menu on the screen, it is not possible to enter
a service mode. Be sure there is no menu on the screen when
attempting to enter a service mode.

5.8.2 Main Power Supply

The simplest way to repair the main supply is to check (and
replace, if necessary) the gray marked components on the
Main Supply.

Do not try to perform measurements on the side of the SSB
connected to the "hot" heatsink. This is dangerous. Most
relevant service test points are connected to the Tuner side
and are pointed out by service printing. Where the circuitry was
too crowded to place this service printing, it has been explained
on the Test Point Overviews in this manual. It is also possible
to use the SSB extension panel (part number: 9965 000

05769), so that all test points are easily accessible.

5.8.3 Standby Power Supply

The simplest way to repair the standby supply is to check (and
replace, if necessary) the gray marked components on the

5.8.4 Horizontal Deflection

The simplest way to repair the horizontal deflection is to check
(and replace, if necessary) the gray marked components on the
Horizontal Line Deflection circuitry.

5.8.5 Vertical Deflection

Caution: When you suspect the Vertical Deflection circuitry,

please be careful. Since there is a DC voltage on the vertical
deflection, the beam current can damage the CRT neck,
leading to a defective CRT.
The best thing to do is:

1. Interrupt pin 2 of connector 1424 on the CRT panel
(diagram F), in order to remove the 'filament' voltage from
the tube (there is no beam current, so there is no chance of
destroying the CRT).

2. Measure the functionality of the Frame stage with a
multimeter or with an oscilloscope.

3. After you have found the cause, exchange the defective
component (for example, TDA8177), and resolder the
interrupted pin 2.
