Safety Instructions, Warnings and Notes

2. Safety Instructions, Warnings and Notes

GB 5FM23 2.

2.1 Safety Instructions

Safety regulations require that during a repair:

• Connect the set to the mains via an isolation transformer

³ 800 VA).

(

• Do not operate the monitor without the front glass plate.
One function of this glass plate is to absorb IR radiation.
Without this glass plate, the level of radiation could
damage your eyes.

• Replace safety components, indicated by the symbol
only by components identical to the original ones.

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 lead for external
damage.

• Check the electrical DC resistance between the mains
plug and the secondary side (only for sets which have a
mains isolated power supply):

1. Unplug the mains cord and connect a wire between

the two pins of the mains plug.

2. Set the mains switch to the 'on' position (keep the

mains cord unplugged!).

3. Measure the resistance value between the pins of

the mains plug and the metal shieldingof the tuner or
the aerial connection on the set. The reading should
be between 4.5 M

4. Switch ‘off’ the set, and remove the wire between the

two pins of the mains plug.

• Check the cabinet for defects, to avoid touching of any
inner parts by the customer.

W and 12 MW.

• The direct voltages and oscillograms shown in the
diagrams are indicative. Measure them in the Service
Default Mode (see chapter 5).

• Where necessary, measure the voltages in the power
supply section both in normal operation (

2.2 Warnings

• Be aware that the mains voltage remains present on the
chassis, even when the mains switch is ‘off’.

• All ICs and many other semiconductors are susceptible
to electrostatic discharges (ESD
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 the danger
of a circuit becoming unstable.

). Careless handling

2.3 Notes

• Clean the glass plate in front of the plasma display with
a slightly humid cloth. If, due to circumstances, there is
some dirt between the glass plate and the plasma
display, this must be cleaned by a qualified service
engineer (see chapter 4).

• Measure the direct voltages and oscillograms with regard
to the chassis ground (

5.3.3 Customer Service Mode (CSM)

Purpose

When a customer is having problems with his TV-set, he can
call his dealer or helpdesk. 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 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 in this
mode are not possible.

5.5 ComPair

5.5.1 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
and is therefore capable of accurately indicating problem
areas. You do not have to know anything about I
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.

5.5.2 Specifications

ComPair consists of a Windows based faultfinding program,
and an RS232 cable between PC and the (defective)
product.

2

C level)

2

C

• Manually (by asking questions to you): Automatic
diagnosis is only possible if the micro controller of the
monitor 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

Does the screen give a picture? Click on the correct

(e.g.

answer: YES / NO

) and showing you examples (e.g.

Measure test-point F7 and click on the correct
oscillogram you see on the oscilloscope

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:

• Software upgrading (upload possible to OTC and PW
Scaler).

• 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) of the SCAVIO

Click on the ‘Panel’ hyperlink to automatically

panel.

show the PWB with a highlighted capacitor C2568. Click
on the ‘Schematic’ hyperlink to automatically show the
position of the highlighted capacitor.

5.5.3 How to Connect

1. First, install the ComPair Browser software on your PC
(read the installation instructions carefully).

2. Connect an RS232 interface cable between a free serial
(COM) port on your PC and the RS232 connector on the
FM23 plasma monitor.

3. Switch the plasma monitor ‘off’ and ‘on’ again (with the
Mains switch).

4. Start the ComPair program and follow the instructions.

Note: once the set is in ComPair mode, the front LED will
blink red, at a frequency of 0.3 Hz.

5.5.4 How to Order

ComPair order codes:

• Starter kit ComPair software (registration version): 4822
727 21634

• ComPair CD (update): 4822 727 21637

• Starter kit SearchMan software: 4822 727 21635

• SearchMan CD (update): 4822 727 21638

Note: The RS232 cable is not included. It is a standard cable
(9p sub-D male-to-female) that can be obtained by a
computer store. It is supplied however with the ComPair
interface (4822 727 21631), necessary for servicing other
Philips TVs.

5.6 Error Buffer

). You can

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

• Automatic (by communication with the monitor):
ComPair can automatically read out the contents of the
entire error buffer. Diagnosis is done on I
ComPair can send and receive commands to the micro
controller of the monitor, and so can access the I
of the monitor. In this way, it is possible for ComPair to
communicate (read and write) to devices on the I

2

C level.

2

C bus

2

C

busses of the FTV monitor.

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.

5.6.1 How to Read the Error Buffer

Use one of the following methods:

• On screen via the SAM (only if you have a picture).
Examples:

Service Modes, Error Codes,Fault Finding, and Repair Tips

GB 17FM23 5.

– ERROR: 60000: Error code 6 is the last and only

detected error

– ERROR: 96000: 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 paragraph 5.7.

• Via ComPair.

5.6.2 How to Clear the Error Buffer

The error code buffer is cleared in the following cases:

• By activation of the ‘Reset error buffer’ command in the
SAM menu:

• When you transmit the code 062599with a standard
remote control transmitter.

Figure 5-6

In case of non-intermittent faults, clear the error buffer before
you begin the repair. This 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).

5.7 The Blinking LED Procedure

260901

When the SDM is entered, or when code 062500is
entered with the remote control, the LED will blink the
contents of the error-buffer.
Error-codes

³ 10 are shown as follows:

–‘n’ long blinks of 750 ms, which is/are 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: 129600
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.

5.8 Protections

You can read the error codes of the error buffer via the
service menu (SAM), the blinking LED procedure or via
ComPair. 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 5
Hz indicates the protection mode.
In some error cases, the microprocessor does not put the set
in the protection mode. The error codes are indicated by an
orange front LED.
To get a quick diagnosis the chassis has three service modes
implemented:

• The Customer Service Mode (CSM): easy way to read
out the status of the set.

• 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.

5.9 Repair Tips

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

• Error code indicates an under- or overvoltage
protection (errors 70 - 74). Possible causes:

– Short-circuit present on PSU.
– Short-circuit present in PSU load circuit.
– Converter not functioning (no start-up, or non short-

circuit failure).

• Set starts up, but switches ‘off’ soon.

1. Check the PSU outputs. If no output at all, verify the

Power Factor Corrector (= PFC or pre-conditioner)
e.g. the relays. When PFC is not switching, the LLC
is actively held off.

2. If PFC works, check V

3. If V

4. If no V

is high, check LLC (V

, check pin 15 (IC7650).

S

5. If voltage is OK, check pins 12 and 14.

6. If no pulses, check controller pin 10.

7. If pin 10 < 1 V, the IC is probably defect.

• If fuse 1004 (diagram P5) is blown: Check items 7005
and 7006. If one of them is defect, replace both!

• If fuse 1400 (diagram P2) is blown: Check diode
bridge 6600, diodes 6606 and 6607 and MOSFET 7610.

).

Via this procedure, you can make the contents of the error
buffer visible via the front LED (orange colour).This is
especially useful when there is no picture. When no errors
are present, the LED will stay green.
