4.2 Set Disassembly

4.3 Service Positions

4.4 Assy / Board Removal

4.5 Set Re-assembly

Note: Figures below can deviate slightly from the actual
situation, due to the different set executions.

4.1 Service Connector (for ComPair)

For service diagnostics with ComPair, it is not necessary to
disassemble the set. You only have to connect the ComPair
interface box, via the appropriate cable, to the service
connector (on the rear of the set, see figure 1-2), and start the
program (see also chapter 5 "Service Modes, Error Codes, and
Fault Finding ").

4.2 Set Disassembly

Follow the disassemble instructions in described order.

4.2.1 Rear Cover Removal

Warning: disconnect the mains power cord before you remove

the rear cover.

1. Remove all the fixation screws of the rear cover.

2. Now the rear cover can be removed.

Solder Side LSP

To get access to the bottom side (solder side) of the LSP, do
the following (see figure 4-1):

1. Remove the connector of the mains cable (coming from the
mains switch-module) from the LSP.

2. Remove the cable (connector) from the side I/O panel.

3. Release some wiring from their fixation clamps, in order to
get room for repositioning the LSP.

4. Flip the LSP 90 degrees clockwise [2], and place it in the
fixation hole at the left side of the bottom tray [3].

5. Push the LSP forward to fix it. (Alternatively, the LSP may
also be placed on your work bench without being
positioned in its fixation hole, or it may even be removed
from the bracket for better accessibility, see “Assy / Board
Removal: Large Signal Panel (LSP)” on the next pages.)

4.3 Service Positions

This chassis has several predefined service positions, for
better accessibility. They are explained below in more detail.

4.3.1 Large Signal Panel (LSP)

Component Side LSP

For better accessibility of the LSP, do the following (see Figure
“Service position 1”):

1. Simultanuously do the following: a) pull the two plastic
locking handles at the mid left and mid right side of the
bracket gently backwards to unlock the bracket, and b)
loosen the bracket from the bottom tray, by pulling it
backwards. N.B.: You do not need to pull the other two
locking handles backwards.

2. Remove the LSP-bracket from the bottom tray by lifting it
upwards.

3. Hook the bracket in the first row of fixation holes of the
bottom tray. In other words, reposition the bracket from [1]
to [2].

Figure 4-2 Service position 2

4.3.2 Small Signal Board (SSB)

In fact, there is no predefined service position for the SSB. Most
test points are located on the A-side (side that is facing the
tuner). If you have to replace ICs, you must take the complete
SSB module out of the SIMM-connector.

Notes:

• For better access to the SSB, it is possible to order an
“extension tool” with cables. You can use this service
extension tool to connect a Small Signal Board (SSB) of an
ES1E, A02, A10, or EMG (EMx) chassis, via two “IDE”
cables to the SIMM connector in the set. In this way, you
can service the SSB more easily outside the TV set. You
can order this tool under 12nc: 9965 000 14526.

• If necessary for the measurement, you can put the LSP in
“service position 2” (as described above).

4.4 Assy / Board Removal

Sometimes, it can be necessary to swap a complete assy or
Printed Wiring Board (PWB). How that can be done is
explained below.

4.4.6 Large Signal Panel (LSP)

1. Remove the SSB (see paragraph “Small Signal Board
(SSB)” above).

2. Remove the two fixation screws from the large plastic
bracket on the right hand side of the LSP (above the EHT
shield), and remove the bracket, after releasing the EHT
cable and the CRT cables from the fixation clamps on this
bracket.

3. Disconnect the other cables (loudspeaker, mains, etc.)
from the LSP, and release some cables from their fixation
clamps.

4. Press the fixation clamp on the left front side of the LSP­bracket (close to the white arrow/loudspeaker connector)
to unlock the LSP, and tilt it upwards (the board hinges at
the right side).

5. Remove the board from the bracket by unhooking it from its
fixation clamps on the right side.

4.5 Set Re-assembly

To re-assemble the whole set, do all processes in reverse
order.
Be sure that, before the rear cover is mounted:

• The mains cord is postioned correctly in its guiding
brackets (make sure that the strain relief will function
correctly!).

• All wires/cables are returned in their original positions. This
is very important, in view of the “hot” and “EHT” areas of the
set.

• Service Default Mode.

• Video: colour bar signal.

• Audio: 3 kHz left, 1 kHz right.

5.2 Service Modes

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 below) and the TV
chassis. It offers the ability of structured troubleshooting, test
pattern generation, error code reading, software version
readout, and software upgrading.
Minimum requirements: a Pentium processor, Windows 95/
98, and a CD-ROM drive (see also paragraph “ComPair”).

5.2.1 Service Default Mode (SDM)

Purpose

• To create a pre-defined setting for measurement purposes.

• To override SW protections (only when SDM is activated
via shorting the SDM pins on the SSB).

• To start the blinking LED procedure.

• Inspection of error buffer, life timer, and software version.

Specifications

• Tuning frequency: 475.25 MHz for PAL/SECAM.

• Colour system: SECAM L for France or PAL B/G for the
rest of Europe.

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

• All sound settings at 50 %, except volume at 25 %.

• All service-unfriendly modes (if present) are disabled, like:
– (Sleep) timer.
– Child/parental lock.

10 minutes).
– Skip/blank of non-favourite pre-sets.
– Hotel or hospital mode.
– Local keyboard block.
– Smart modes.
– Auto store of personal presets.
– Auto user menu time-out.

How to Activate SDM

Use one of the following methods:

• Use the standard RC-transmitter and key in the code
“062596”, directly followed by the “MENU” button.

Note: It is possible that, together with the SDM, the main
menu will appear. To switch it "off", push the “MENU”
button again.

• Short circuit, during switch "on" of the set, the two solder
pads on the SSB with the indication “FOR SERVICE”.
These solder pads are located at the "tuner" side of the
SSB (just above the large BGA IC).
Caution: If the SDM is activated via these pins, all the
software-controlled protections are de-activated for 15 s.
When these 15 s are expired, the set will shutdown to
protection mode.

• Use the DST-emulation feature of ComPair.

After activating this mode:

• “SDM” will appear in the upper right corner of the screen.

• Also, the error buffer, operating hours, and software
version are displayed (can be toggled "on/off" with the
"STATUS / OSD / [i+]" button).

• Blinking LED procedure will be started.

• All software-controlled protections are overridden for 15 s.
When these 15 s are expired, the set will shutdown to
protection mode.

Contents of SDM:

• HRS. Displays the accumulated total of operation hours
(not the standby hours) in hexadecimal value.

• SW. Displays the date of the software and the software
version of the ROM;
example: A2EU04-5.10 = AAABBC-X.YY.
– AAA= chassis name.
– BB= region and/or function name: E= Europe, A= Asia

Pacific, U= NAFTA, L= LATAM, B= Basic, T= Top, P=

PAL, N= NTSC, S= Stereo, M= Mono.
– C= the language cluster number.
– X.Y= the software version, where X is the main version

number (different numbers are not compatible with one

another) and Y is the sub version number (a higher

number is always compatible with a lower number).

• ERR (followed by maximal 8 errors). The most recent error
is displayed at the upper left (for an error explanation see
paragraph “Error Codes”).

How to Navigate

• When you press the “MENU” button on the RC transmitter,
the set will toggle between the SDM and the normal user
menu (with the SDM mode still active in the background).

• When you press the “STATUS / OSD / [i+]” button on the
RC transmitter, the set will toggle between the full SDM
screen or a screen with only the text "SDM" displayed on it.
This mode is useful when performing measurements, then
the OSD info will not generate interference.

How to Exit SDM

Use one of the following methods:

• Switch the set to STANDBY via a standard customer RC­transmitter (the error buffer is erased).

• Via a standard customer RC-transmitter: key in “00”­sequence (the error buffer is not erased).

5.2.2 Service Alignment Mode (SAM)

Note: Alignments are described in chapter 8 "Alignments".

How to Navigate

• In SAM, you can select the menu items with the “CURSOR
UP/DOWN” key on the RC-transmitter. The selected item
will be highlighted. When not all menu items fit on the
screen, move the “CURSOR UP/DOWN” key to display the
next/previous menu items.

• With the “CURSOR LEFT/RIGHT” keys, it is possible to:
– (De) activate the selected menu item.
– Change the value of the selected menu item.
– Activate the selected submenu.

• When you press the “MENU” button on the RC transmitter,
the set will toggle between the SAM and the normal user
menu (with the SAM mode still active in the background).

How to Exit SAM

Use one of the following methods:

• Switch the set to STANDBY via the RC-transmitter (the
error buffer is erased).

• Via a standard customer RC-transmitter: key in “00”­sequence (the error buffer is not erased).

5.2.3 Customer Service Mode (CSM)

Purpose

When a customer is having problems with his TV-set, he can
call his dealer or the Philips helpdesk (P3C). 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 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 in this
mode are not possible.

How to Activate CSM

Use one of the following methods:

• Press the “MUTE” button on the RC-transmitter
simultaneously with any key on the TV for at least 4
seconds.

• Key in the code “123654” via the standard RC transmitter.

Notes:

• Activation of the CSM is only possible if there is no (user)
menu on the screen!

• During CSM, sound volume is set to 25% of the scale,
"Smart Sound" is set to "Theatre" mode, and "Smart
Picture" is set to "Rich/Movies" mode temporarily to ensure
a good picture and sound of the working set. After leaving
CSM, the original settings are restored.

How to Navigate

By means of the “CURSOR-DOWN/UP” knob on the RC­transmitter, you can navigate through the menus.

of the “CHANNEL”, “VOLUME” and digit (0-9) keys), or

• After you switch the TV-set “OFF” with the mains switch.

• After 15 min. no RC or local keyboard actions.

5.3 Problems and Solving Tips (related to CSM)

Note: The problems described below are all related to the TV

settings. The procedures to change the value (or status) of the
different settings are described above. New value(s) are
automatically stored.

5.3.1 Picture Problems

Picture too Dark

1. Press SMART PICTURE on the RC. In case the picture
improves, increase the “Brightness” or the “Contrast”
value. The new value(s) are automatically stored (in
“personal” pre-set) for all TV channels.

2. Check in CSM lines BRIGHTNESS and/or CONTRAST. If
the value of line BRIGHTNESS is low (< 10) or the value of
line CONTRAST is low (< 10), increase them.

Picture too Bright

1. Press SMART PICTURE on the RC. In case the picture
improves, decrease the “Brightness” or the “Contrast”
value. The new value(s) are automatically stored (in
“personal” pre-set) for all TV channels.

2. Check in CSM lines BRIGHTNESS and/or CONTRAST. If
the value of line BRIGHTNESS is high (> 50) or the value
of line CONTRAST is high (> 50), decrease the
“Brightness” or the “Contrast” value.

White Line Around Picture Elements and Text

1. Press SMART PICTURE on the RC. In case the picture
improves, decrease the “Sharpness” value. The new value
is automatically stored (in “personal” pre-set) for all TV
channels.

2. Check in CSM line SHARPNESS. Decrease the
“Sharpness” value. The new value is automatically stored
for all TV channels.

No Picture

Check in CSM line 10 (SIGNAL). In case this line shows NO
SIGNAL, check the aerial cable/aerial system.

Blue Picture

No proper signal is received. Check the aerial cable/aerial
system.

Blue Picture and/or Unstable Picture

A scrambled or coded signal is received.

Black and White Picture

Check in CSM line COLOR. In case the value is low (< 10),
increase the “Color” value. The new value is automatically
stored for all TV channels.

No Colours/colour Lines around Picture Elements or Colours not Correct or Unstable Picture

1. Check in CSM line SYSTEM. If a “strange” system pops up,
something has gone wrong during installation. Re-install
the channel.

2. In case line SYSTEM is “FRANCE”, the installed system for
this pre-set is SECAM, while PAL is required. Install the
required program again: open the installation menu and
perform manual installation. Select system “West Europe”.

Menu Text not Sharp Enough

1. Press “SMART PICTURE”. In case picture improves,
decrease the "Contrast" value. The new value(s) are
automatically stored for all TV channels.

2. Check in CSM line CONTRAST. If the value of this line is
high (> 50), decrease the "Contrast" value.

5.3.2 Sound Problems

No Sound from Left and Right Speaker

Check in CSM line VOLUME. If the value is high, increase the
value of “Volume”. The new value(s) are automatically stored
(in “personal” pre-set) for all TV channels.

Sound too Loud for Left and Right Speaker

Check in CSM line VOLUME. If the value is low, decrease the
value of “Volume”. The new value(s) are automatically stored
(in “personal” pre-set) for all TV channels.

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 (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.
For this chassis, the ComPair interface box and the TV
communicate via a bi-directional service cable via the service
connector.

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

• Automatically (by communicating with the television set):
ComPair can automatically read out the contents of the

2

C level) and

2

C commands

Service Modes, Error Codes, and Fault Finding

EN 13ES1E 5.

entire error buffer. Diagnosis is done on I2C level. ComPair
can access the I
and receive I

2

C bus of the television. ComPair can send

2

C commands to and from the micro controller
of the television set. In this way, it is possible for ComPair
to communicate (read and write) to devices on the I
busses of the TV-set.

• Manually (by asking questions to you): This option is
helpful, because automatic diagnosis is only possible if the
micro controller of the television is working correctly (also,
the diagnostic possibilities of automatic diagnosis are more
limited). When you choose manual diagnosis, 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 by 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. a piece of 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:

• Up- or downloading of pre-sets.

• Managing of pre-set lists.

• Emulation of the 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 Mono-carrier.

– 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.

• SW upgrading

5.4.3 How To Order

When multiple errors occur (errors occurred within a short time
span), there is a high probability that there is some relation
between them.

C

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:
– 0 0 0 0: No errors detected
– 6 0 0 0: Error code 6 is the last and only detected error
– 9 6 0 0: Error code 6 was first detected and error code

9 is the last detected error

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

•Via ComPair.

5.5.3 How to Clear the Error Buffer

Use one of the following methods:

• By activation of the “CLEAR ERRORS” command in the
SAM menu.

• With a normal RC, key in sequence “MUTE” followed by
“062599” and “OK”.

• When you transmit the commands “DIAGNOSE” - “99” ­“OK” with ComPair (or with a DST).

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

5.5.4 Error Codes

The function of error codes is to indicate failures in the TV set.
In principle a unique error code is available for every:

2

•I

C device error.

•I

C bus error (for every bus containing two or more I2C

devices).

• Protection error (e.g. +8V protection or Horizontal
protection).

• Error not related to an I

C device, but of importance (e.g.

BC-loop, RAM error).

5.5 Error Codes

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, new errors are logged at the left side, and all other errors
shift one position to the right.
When an error has occurred, the error is added to the list of
errors, provided the list is not full or the error is a protection
error.
When an error occurs and the error buffer is full, then the new
error is not added, and the error buffer stays intact (history is
maintained), except when the error is a protection error.
To prevent that an occasional error stays in the list forever, the
error is removed from the list after 50+ operation hours.

Service Tips:

• 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. Before clearing the buffer,
write down the content, as this history can give you
significant information.

• 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).

operation” mode and in “protection” mode). In order to
avoid confusion with RC5 signal reception blinking, this
LED blinking procedure is terminated when an RC5
command is received.

• Transmit the commands “MUTE”, “06250x”, and “OK” with
a normal RC (where “x” is the position in the error buffer
that has to be displayed). With x= 1, the last detected error

is shown, x= 2 the second last error, etc.... When x= 0, all

errors are shown.

• “DIAGNOSE X” with the DST (where “x” is the position in
the error buffer that has to be displayed). With x= 1, the last

detected error is shown, x= 2 the second last error, etc....

When x= 0, all errors are shown.

Note: It can take some seconds before the blinking LED starts.

5.7 Software Downloading

In this chassis, you can upgrade the software via ComPair.
You can find more information on how this procedure works in
the ComPair file. It is possible that not all sets are equipped
with the hardware, needed to make software upgrading
possible. To speed up the programming process the firmware
of the ComPair interface can be upgraded. See paragraph
“How To Order” for the order numbers.

5.6 The Blinking LED Procedure

5.6.1 Introduction

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 activated, the front LED will show (by
blinking) the contents of the error-buffer. Error-codes > 10 are
shown as follows:

1. A long blink of 750 ms (which is an indication of the decimal
digit),

2. A pause of 1500 ms,

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

4. When all the error-codes are displayed, the sequence
finishes with a LED blink of 3000 ms,

5. The sequence starts again.

Example: Error 12 9 6 0 0.
After activation of the SDM, the front LED will show:

1. 1 long blink of 750 ms (which is an indication of the decimal
digit) followed by a pause of 1500 ms,

2. 2 short blinks of 250 ms, followed by a pause of 3000 ms,

3. 9 short blinks of 250 ms, followed by a pause of 3000 ms,

4. 6 short blinks of 250 ms, followed by a pause of 3000 ms,

5. 1 long blink of 3000 ms to finish the sequence,

6. The sequence starts again.

5.6.2 How to Activate

Use one of the following methods:

• Activate the SDM (only via soldering pads marked “FOR
SERVICE” on the SSB). The blinking front LED will show
the entire contents of the error buffer (this works in “normal
