Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

EN 5FM242 AA 2.

2.1 Safety Instructions

Safety regulations require that during a repair:

• Connect the set to the mains via an isolation transformer
(> 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 shielding of the tuner or the
aerial connection on the set. The reading should be
between 4.5 MΩ and 12 MΩ.

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.

2.2 Warnings

• All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD ). 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 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.

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
section “Mechanical Instructions”).

• Measure the direct voltages and oscillograms with regard
to the chassis ground (), or hot ground () as this is
called.

• The direct voltages and oscillograms shown in the
diagrams are indicative. Measure them in the Service
Default Mode (see section “Service Modes”).

,

• Where necessary, measure the voltages in the power

supply section both in normal operation () and in standby
(). 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

2.3.1 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.

2.3.2 Rework on BGA 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, it is essential when
removing an (LF)BGA that 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.

-

EN 6 FM242 AA2.

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.

4.1 Service Position Monitor

Figure 4-1 Service Position

First, put the monitor in its service position. (Can be done via
buffers as showed on figure, but preferable via new service
position solution as described below. Still some improvising is
needed for service positions panels however). Therefore,
disconnect all cables connected to the monitor and take the
monitor of the wall (or tabletop stand). Then, fix the monitor to
the 2 service-poles. (the 2 poles together form a service-kit:
3122 785 90480; this service-stand can be used for 30” until
42” FTVs.

EN 13FM242 AA 5.

5.2.1 Service Default Mode (SDM)

Service Default Mode (SDM) and Service Alignment Mode
(SAM) offer several features for the service technician, while
the Customer Service Mode (CSM) is used for communication
between a Philips Customer Care Centre (P3C) and a
customer.

There is also the option of using ComPair, a hardware interface
between a computer (see requirements) and the FTV chassis.
It offers the ability of structured trouble shooting, test pattern
generation, error code reading, software version readout and
software upgrading.
Minimum requirements: a Pentium Processor, Windows 9x/NT/
2000/XP, and a CD-ROM drive (see also paragraph
“ComPair”).

Note: This FM242-monitor has different as the FM24, not a
internal pdp-testpattern that can be enabled via the SAM­menu
A test pattern however can be generated.
How?
Select via ComPair-tool the right hex-address (sub
address 0080 and then PS (Pattern Select) (00 full window
black; 01~04 full window white, red, green, blue) and more
variants until 17)
It however only works when set is signalled (Scavio and
pdp, needs a sync). This is less nice solution as in FM24.
Switch off the pattern again via hex-code 0080 and 0

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 severe
ness 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.

5.4 ComPair

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 (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
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 RS232 cable between PC and the (defective) product.

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 I2C level. ComPair can send
and receive commands to the micro controller of the
monitor, and so can access the I2C bus of the monitor. In
this way, it is possible for ComPair to communicate (read
and write) to devices on the I2C busses of the FTV monitor.

• 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 (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.

2

C level) and

2

C commands

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 panel. 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 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

FM242 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.

5.4.4 How to Order

ComPair order codes:

• Starter kit ComPair32 software (registration version): 3122

785 60040.

• ComPair32 CD (update): 3122 785 60070.

• Starter kit SearchMan32 software: 3122 785 60050.

• SearchMan32 CD (update): 3122 785 60080.

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.

5.5 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:

–Errors: 6 0 0 0 0, error code 6 is the last and only

detected error.

–Errors: 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 paragraph “The blinking led procedure”.

•Via ComPair.

Service Modes, Error Codes and Fault Finding

EN 17FM242 AA 5.

5.5.2 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 062599 with a standard
remote control transmitter.

Notes:

• 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).

• In case error 70 occurs, the belonging over-voltage line
cause can be located via measuring. (via measuring all 4
voltages simultaneously with an oscilloscope). Chosen

5.6 The Blinking LED Procedure

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.

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

Error-codes ≥ 10 are shown as follows:

1. n long blinks of 750 ms, which is/are an indication of the
decimal digit,

2. a pause of 1.5 s,

3. n short blinks (n = 1-9),

4. when all the error-codes are displayed, the sequence
finishes with a LED blink of 3 s,

5. the sequence starts again.

Example of error buffer: 12 9 6 0 0
After entering SDM:

1. 1 long blink of 750 ms followed by a pause of 1.5 s,

2. 2 short blinks followed by a pause of 3 s,

3. 9 short blinks followed by a pause of 3 s,

4. 6 short blinks followed by a pause of 3 s,

5. 1 long blink of 3 s to finish the sequence,

6. the sequence starts again.

5.7 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.

Exceptional ‘protection’ situation

There exists one ‘protection’ (due to too high internal set­temperature), where the set does not switch to ‘protection’­mode but to Standby-mode. This protection is not logged into
the error-buffer.
When the set becomes too warm, an ‘On Screen Display’­message will be showed set is going to switch to Standby. After
some time set can be switched on again. (It is very unlikely this
will happen. For that reason this performance has been
accepted).

Temperature error

The monitor will switch to standby
automatically.
Please allow cool down.

EN 18 FM242 AA5.

5.8 Repair Tips

If one of the errors of the error buffer points to a defective
supply, then the supply-panel must be send for central repair.
If the symptoms (still to be communicated; e.g. when VS-value
is too high some pixels do not extinguish, when VS-value is too
low some pixels do not enlighten) match with a possible
misalignment of a supply-line, this supply-line could be
checked, and re-aligned.
Only do this if there is a slight spec-violation.
In case it does not help, re-align to the previous wrong setting,
to keep cause-image in tact, for central repair workshop.
Replace supply panel by a new one, and match the supply with
the pdp. (See alignment instructions in chapter “Alignments”).
