Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
Index of this chapter:
2.1 Safety Instructions
2.2 Maintenance Instructions
2.3 Warnings
2.4 Notes
2.1Safety Instructions
Safety regulations require the following during a repair:
•Connect the set to the Mains (AC Power) via an isolation
transformer (> 800 VA).
•Replace safety components, indicated by the symbol h,
only by components identical to the original ones. Any
other component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
•Wear safety goggles when you replace the CRT.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay in 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 flows. In particular this is valid
for the:
1. Pins of the line output transformer (LOT).
2. Fly-back 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 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 Mains (AC Power) lead for
external damage.
•Check the strain relief of the mains (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 Mains (AC
Power) plug and the secondary side (only for sets that have
a Mains (AC Power) isolated power supply):
1. Unplug the Mains (AC Power) cord and connect a wire
between the two pins of the Mains (AC Power) plug.
2. Set the Mains (AC Power) switch to the "on" position
(keep the Mains (AC Power) cord unplugged!).
3. Measure the resistance value between the pins of the
Mains (AC Power) plug and the metal shielding of the
tuner or the aerial connection on the set. The reading
should be between 4.5 Mohm and 12 Mohm.
4. Switch "off" the set, and remove the wire between the
two pins of the Mains (AC Power) plug.
•Check the cabinet for defects, to prevent touching of any
inner parts by the customer.
2.2Maintenance Instructions
We recommend a maintenance inspection carried out by
qualified service personnel. The interval depends on the usage
conditions:
•When a customer uses the set under normal
circumstances, for example in a living room, the
recommended interval is three to five years.
•When a customer uses the set 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.
2.3Warnings
•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 figure “Discharge
picture tube”, to discharge the picture tube. Use a high
voltage probe and a multi-meter (position V
until the meter reading is 0 V (after approx. 30 s).
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. 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 prevents circuits
from becoming unstable.
2.4Notes
2.4.1General
•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.

•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.
2.4.3Rework 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 is being removed, 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 risk 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 been 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.
So as not to damage neighbouring components, it may be
necessary to reduce some temperatures and times.
More Information
For more information on how to handle BGA devices, visit this
URL: www.atyourservice.ce.philips.com (needs subscription,
not available for all regions). After login, select “Magazine”,
then go to “Workshop Information”. Here you will find
Information on how to deal with BGA-ICs.
Figure 2-3 Lead-free logo
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 a solder-tip temperature of at least 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 of 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 increase 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 this cannot be avoided, carefully
clean 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
shortly 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!
EN 6ES1E2.
•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 the
mixing 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 repair help
desk.
2.4.5Practical 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 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.
Safety Instructions, Warnings, and Notes
3.Directions for Use
You can download this information from the following websites:
Note: Figures below can deviate slightly from the actual
situation, due to the different set executions.
4.1Service 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 ").
4.2Set Disassembly
Follow the disassemble instructions in described order.
4.2.1Rear 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.)

4.3Service Positions
This chassis has several predefined service positions, for
better accessibility. They are explained below in more detail.
4.3.1Large 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].
CL 36532058_078.eps

Figure 4-2 Service position 2
4.3.2Small 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).
4.4Assy / 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.

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.
4.5Set 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.

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.

5.2.3Customer 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.

•After 15 min. no RC or local keyboard actions.
5.3Problems 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.
5.3.1Picture 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.
5.3.2Sound 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.
5.4ComPair
5.4.1Introduction
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.
5.4.2Specifications
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 13ES1E5.
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
5.4.3How 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
5.5.2How 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.
5.5.3How 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.
5.5.4Error 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.
2
•I
C bus error (for every bus containing two or more I2C
devices).
•Protection error (e.g. +8V protection or Horizontal
protection).
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.
5.7Software 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.
5.6The Blinking LED Procedure
5.6.1Introduction
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.
5.6.2How 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

8.2.1Vg2 Adjustment
In the frame-blanking period of the R, G, and B signals applied
to the CRT, the video processor inserts a measuring pulse with
different DC levels. Measure the black level pulse during the
vertical flyback at the RGB cathodes of the CRT.
1. Connect the RF output of a pattern generator to the
antenna input. Input a "black" picture (blank screen on CRT
without any OSD info) test pattern.
2. In the SAM mode, set the “Normal Red”, “Normal Green”
and “Normal Blue” values to “0” for “White Tone”.
3. Disable the black current loop (via the AKB bit).
4. Use the MENU key to enter the "user" menu, select
"Picture", and set "Brightness" and "Contrast" to “0”.
5. Set the oscilloscope to 20 V/div and the time base to 20 us/
div. Use external triggering on the vertical pulse.
Caution: use a trigger point on the "cold" side!
6. Ground the scope on the CRT panel ("cold" side) and
connect a 10:1 probe to one of the cathodes of the picture
tube socket (see circuit diagram B1).
7. Measure at test points F338, F339 and F341 on the picture
tube socket the DC-level of the measuring pulse (1st full
line after the frame blanking) with respect to earth.
8. Select the pin with the highest level found and adjust
V_cutoff by means of the Vg2-potmeter (lowest-one) on the
Line Output Transformer (LOT) to 160 +/- 5 V
screen sizes).
9. Reset "Contrast" and "Brightness" to their original values.

8.2.2Focus alignment
The LOT has the following outline:
– Focus 1 (F1) = Static alignment (red wire).
– Focus 2 (F2) = Dynamic alignment (white wire).
1. Use an external video pattern generator to input a "circle"
or "crosshatch" test pattern to the set.
2. Choose "Natural" picture mode with the "Smart Picture"
button on the remote control transmitter.
3. Adjust the "dynamic focus 2" potentiometer (in the middle
on the LOT) until the horizontal lines at the centre of the
screen are of minimum width without introducing a visible
haze.
4. Adjust the "static focus 1" potentiometer (highest of the
LOT) until the horizontal lines at the sides of the screen are
of minimum width without introducing a visible haze.
5. Repeat these two steps to achieve the best result.
8.3Software Alignments
Put the set in the SAM (see the "Service Modes, Error Codes
and Fault Finding" section). The SAM menu will now appear on
the screen. The different alignment parameters are described
further on.
Notes:
•All changes to menu items and alignments must be stored
manually.
•If an empty EAROM (permanent memory) is detected, all
settings are set to pre-programmed default values, so the
set must be re-aligned.
– For "Negative modulation", on SCART pin 1 or 3
(audio out): Adjust IF-PLL OFFSET until the largest
Signal Noise Ratio (SNR) is reached.
– For "Positive modulation", on SCART pin 19 (video
out): Adjust IF-PLL OFFSET until you get minimal Vsync disturbance.
8.3.2Geometry
Notes:
•Set an external pattern generator to a crosshatch video
signal and connect the RF output to the aerial input of the
TV. Set the amplitude at least 1 mV
frequency to 475.25 MHz. Use system PAL B/G if possible,
otherwise match the system of your generator with the
received signal in the set.
Note: Do not use the internal test pattern from the
GEOMETRY menu!
•Use the default alignment settings, but set "Brightness" to
"32".
•For wide screen models, set to "wide screen" mode, for
"classic" models, set to "4:3".
•After alignment, save the value(s) with the STORE
command in the SAM main menu.
Service tip: When the set is equipped with a rotation coil, use
this menu item to check its correct alignment. If alignment is not
correct, go to the user MENU, choose FEATURES, and select
ROTATION. With the use of a crosshatch test pattern, align it
to a correct horizontal picture.

•The new option setting is only active after the TV is
switched "off" and "on" again with the Mains switch (the
EAROM is then read again).
8.4.2Changing Options
Options are used to control the presence / absence of certain
features and hardware. There are two ways to change the
option settings. All changes in the option settings are saved by
selecting STORE and pressing the CURSOR RIGHT key.
Some changes will only take affect after the set has been
switched OFF and ON with the mains switch (cold start).
Changing Multiple Options by Changing Option Byte
Values
Option Bytes (OB) makes it possible to set all options very fast.
An option byte represents a number of different options. All
options are controlled via option bytes (OB1 to OB13; each
“OB” number represents 16 bits; bit numbers that are not used
are omitted in the second column). Select an Option Byte you
want to change with the CURSOR UP/DOWN keys, and key in
the new value. See the table for more details. An explanation
per option is listed in paragraph "Option Bit Definition".
Changing a Single Option
It is also possible to change an option one at a time. Therefore,
select the option with the CURSOR UP/DOWN keys and
change its setting with the LEFT/RIGHT keys.
8.4.3Option Settings
In the table below, you will find the option settings.
8.3.4Sound
No adjustments needed. Use the given default values:
The microprocessor communicates with a large number of I
ICs in the set. To ensure good communication and to make
digital diagnosis possible, the microprocessor has to know
which ICs to address. The presence / absence of these specific
ICs (or functions) is made known by the option codes.

9.1Introduction
The ES1E is a flat screen type CRT TV set for the year 2005 -
2006. It is based on the SSB of the A02, but the LSP, called
Esplanade, has been redesigned in order to reduce the “hot”
part of the chassis. In this chapter, only the deflection circuits,
the correction circuits and the X-ray protection circuits are
described.
9.1.1Large Signal Panel
The Esplanade chassis has a full sized LSP, which is has been
redesigned with respect to the previous A02 chassis in order to
reduce the “hot” parts of the circuit.
The main functionalities of the LSP are:
•Supply,
•Deflection,
•Sound amplification.
The LSP (single sided) is built up very conventional, with hardly
any surface mounted components on the copper side.

the horizontal deflection will bend the electron beam from the

At T1 line transistor 7405 is switched off and the line fly-back
starts. When the line transistor stops conducting, the line
current is at its maximum level. The current charges fly-back
capacitors 2412 and 2413, and also capacitor 2414. This
causes a decrease of line current. (Note that this current has a
half-cosine waveform). The deflection position (i.e. the electron
beam) is in the middle of the screen now.

At T2 the deflection current is 0 Amp. The fly-back capacitor
(2412/2413/2414) is charged to approximately 1200 V and will
discharge now. As a result of this, the deflection current will
bend the electron beam to the left of the screen.

When the fly-back capacitor (2412/2413/2414) is discharged,
the current is at its maximum negative level. This maximum
negative current will then charge the fly-back capacitor (2412/
2413/2414) with a negative voltage. At this moment, fly-back
diode 6404 will start conducting. The voltage at Scap 2418
causes a linear current flow from T3 - T4. This causes a
deflection current which bends the electron beam back from
the left to the centre of the screen.
9.2.2Standby and Start Up
T
T4
F_15040_049.eps
040405
In Standby mode, both +5V and Vbatt are not available in order
to meet the standby power saving requirement.
During the start-up phase, +5V is switched on by STANDBY via
7548/7547/7545 and Vbatt is switched on by STANDBY via
7573.
After this, Hdrive is output from the SSB to driver 7404 (see
circuit diagram A2), and consequently to the deflection output
stage (7405). During the slow start-up phase, the Hdrive duty
cycle gradually increases from small to normal. At the
Circuit Descriptions, Abbreviation List, and IC Data Sheets
EN 91ES1E9.
beginning of the start-up phase, the driver receives its +5V
supply via 3421 and 6465 (see circuit diagram A2). During the
slow start-up phase, the LOT 5450 pin9 voltage gradually
increases, and finally takes over the supply of the +5V voltage,
to supply 5402/7404 via 6403/3493/3451/3419/3432/3415/
3414.
At the end of the slow start-up phase, the deflection stage is
operating at its normal operating condition and all the voltages
are stabilized. Then, the +13V volt supply has fully replaced the
+5V supply to power the horizontal output stage.
At that moment, not only the horizontal deflection, but also the
vertical deflection is functioning at its normal operating
conditions.
9.2.3Normal Operation and Horizontal Deflection
In normal operation mode, the Hdrive with its 45/55 duty cycle
is switching on and off 7404 (see circuit diagram A2). The driver
stage is working in flyback mode: When 7404 is on, 5402
retains its flux energy and also switches off 7405 via its
secondary coil during flyback mode. When 7404 is switched
off, 5402 releases its energy and turns on 7405. By means of
the on-off switching process, a sawtooth yoke deflection
current is generated.
There are various circuits that are part of the horizontal
deflection circuit.
These will be discussed below:
Horizontal Output Stage:
This a standard circuit (see circuit diagram A2), in which the
main horizontal output stage consists of driver 7404/5402, line
output transistor 7405, tuning capacitor 2411/2414, Scap 2417/
2418 and diode modulator 6404/2413/2416.
Anti-Curtain Effect (Anti-Beta Ringing) Circuit:
5410/2427/3433 (see circuit diagram A2) are the anti-beta
ringing circuit that is tuned to and suppresses the parasitic
ringing frequencies normally occurring in Slot type LOTs to an
acceptable level. For Layer type LOTs, these components are
not required and 9410 is the jumper alternative for Layer type
LOTs.
Beta Ringing, if not suppressed, will cause a type of
interference which is visible as a curtain effect at the left edge
of the screen. This interference is caused by the high amplitude
ringing energy being coupled magnetically or via an electrically
conducting path from the LOT to the small signal circuit. If the
ringing is suppressed to a specific level, the interference will
not be visible anymore.
DAF Circuit:
5455/2402/2403/2405/2406 (see circuit diagram A2) are the
DAF circuit that will be used in DAF or double focus CRT tubes.
For single focus tubes, these components are not required;
9411 is the jumper alternative for non-DAF tubes.
The DAF circuit is used to improve the dynamic focusing of the
tube, particularly in the edge areas. The DC high voltage of
constant level which is supplied to the focus electrode is
referred to as static focus or single focus. In addition to that, an
AC parabolic waveform (derived from the vertical and/or the
horizontal deflection voltages) can be superimposed onto the
DC static focus voltage; this extra AC focusing voltage will then
correct the focus dynamically, corresponding to the scan
position at that particular moment. This is what we refer to as
DAF (Dynamic Astigmatism and Focusing; a method to keep
the electron spot round and focused during the whole scan).
Transformer 5455 takes the horizontal deflection current as its
input and transfers its energy to the capacitor (2402/2403/
2405/2406) on its secondary side. The current in the secondary
coil of the transformer charges the capacitor and this results in
a parabolic waveform. The parabolic waveform is fed to
connector 1402 of the LOT focus cable and is coupled via an
internal 500 pF capacitor inside the LOT and superimposed
onto the static focus voltage.
2nd order S-correction circuit:
5406/2407/3403 (see circuit diagram A2) are the 2nd order Scorrection circuit, which is used mainly in large wide screen
tubes, because they are prone to scanning imperfections that
need 2nd order S-correction. For 4x3 tubes or relatively small
wide screen tubes, these components are not required, and
then 9401 is the jumper alternative for them.
Due to the relatively wide angle of large wide screen flat tubes,
the inner tube surface (which is flat) and the surface scanned
by the electron beam (which is spherical) are very far apart,
especially at the edges. This is because both areas are
nowhere parallel with respect to each other (as they ideally
would have to be). The larger and wider the screen size is, the
more visible the unwanted phenomenon resulting from this
optical misalignment will be. The phenomenon manifests itself,
because the horizontal scanning will be wider at the 1/4 and 3/
4 position, but narrower at the centre and edge position. Note
that this is different from S-correction (correct centre-versusedge scanning) and Linearity Correction (correct left-versusright scanning).
To carry out the 2nd order S-correction, transformer 5406 takes
the horizontal deflection current as its input and transfers it to
capacitor 2407 on its secondary side. Together with the yoke
coil, capacitor 2407 forms a tuning circuit, and this circuit
modifies the yoke current during the 1/4 and 3/4 scanning
position. In this way, the modified yoke currect compensates
the imperfections that are caused by the CRT geometry.
The function of resistor 3403 is to prevent the secondary circuit
from floating. It pulls DC components of the correction voltages
to gnd.
Dynamic S-correction Circuit (Inner-Pincushion):
5408/5409/2419 (see circuit diagram A2) form the dynamic Scorrection circuit, which is mainly used in relatively large wide
screen tubes. This is, because they are prone to optical inner
pincushion distortions. For 4x3 tubes or relatively small wide
screen tubes, these components are not required; in that case,
9412 is the jumper alternative for them.
As has been explained earlier, due to the relatively wide angle
of large wide screen flat tubes, the inner tube surface (flat) and
the scanning surface (spherical) can never be perfectly parallel
to each other, so optical distortions will be the result, especially
at the edges of the screen. The first imperfection that will
become visible is the phenomenon called pin-cushion
distortion; this can be corrected by the East West circuit for
distortions in the proportions of the top/bottom versus centre
area (distortions in the proportions in the vertical direction have
to be corrected as well, see further down in this text).
Additionally, the larger and wider the screen size becomes, the
more clearly a second unwanted phenomenon will become
visible, called inner pincushion distortion. This happens
because, when two corresponding horizontal scanning lines
are compared, the top one and the centre one will have
different centre-versus-edge scanning length ratios (when the
vertical line at the edge of the screen has been corrected by the
East West circuit, the vertical lines at the 1/4 and 3/4 positions
will still be concave. Note that this phenomenon is different
from 2nd-order S-distortion.)
To correct the dynamic S-distortion, the East West correction
circuit has to generate a deflection current which is higher at
the centre scanning position of the screen than at the top/
bottom positions. With the Bridge coil 5408/5409, this higher
EN 92ES1E9.
Circuit Descriptions, Abbreviation List, and IC Data Sheets
extra current generates a parabolic waveform across 2419 at
the centre scanning position. The parabolic waveform is
superimposed (series-added) onto the S-cap voltage (2417/
2418); in this way, a more parabolic waveform is obtained
which corrects the inner pincushion distortion.
East West correction Circuit:
Together with diode modulator 2413/2416/6404, components
6471/7406/3425/2425 form the main East-West correction
circuit. The circuit is a current drive circuit driven by MOSFET
7406. 3425 and 2425 function as a simple RC filter with the task
of filtering the horizontal pulses in the diode modulator stage.
The parabolic current source for the EW-drive comes from the
SSB and modulates the diode modulator voltage by means of
7406. Because 7406 is in series with Scap 2417/2418), the
diode modulator voltage plus the Scap voltage are always
equal to Vbatt. So, by modulating the diode modulator voltage,
we are able to modulate the Scap voltage, and so the deflection
current and scanning width as well.
EHT-info Compensation:
In addition to the EHT-info compensation feedback to the SSB
IC, components 3422/3423/6424/3424/3435/6425/3437/2437/
2422 are the EHT-info compensation circuit that injects beam
information into the East-West correction circuit to achieve
better compensation.
Waveform "EHT-info" is a voltage source which is derived from
Ibeam; the voltage is injected via the EHT-info compensation
circuit mentioned above, and modulates the East West circuit.
Beam Current and Horizontal Flyback:
The beam current is determined by 3480/3491/3453/3492/
6478 (see circuit diagram A2), while 2450/2451 filters out the
high frequency info.
The horizontal flyback circuit is provided with an X-ray
protection function; for this reason the combined circuit bears
the name Hfb_Xray_Prot. Hfb is derived from the heater pulses
via 2477 and 2476 and clamped by 3477/6474. The protection
is realized by 7486. The SSB monitors the Hfb_Xray_Prot
voltage and will go into protection mode if this voltage is low
without pulses.
damaged if the vertical scanning circuit is not working and all
the beam energy is concentrated on one spot of the CRT neck.
The function of diode 6457 is to isolate the small signal supply
from the flyback supply boost up voltages.
9.2.5Protection
The protections are realized by 7407/7456/7486. All the
protection voltages coming from the various protection circuits
like: the vertical protection (3459/6459), the bridge coil
protection (5411/6405/3479), the X-ray protection (6480/7408/
3460/3462/3465/3469) and the East West protection (7403/
3473/3488/3417/2495) are combined in 7407/7456/7586.
If a protection circuit is triggered, the protection triggering
voltage will turn on 7407 and consequently 7486, which will pull
the Hfb-Xray_Prot voltage low. The SSB will respond to this
triggering signal and will shut down the deflection circuit
9.3Software Upgrading
In this chassis, you can upgrade the software via ComPair.
This offers the possibility, to replace the entire SW image
without having to remove the flash-RAM from its socket. 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 Chapter "Service
Modes ..."; paragraph "ComPair" - “How To Order” for the order
number.
9.2.4Vertical Deflection
IC 7455 (see circuit diagram A2) is the differential vertical
deflection amplifier. The amplification gain is determined only
by 3461/3476 and 3470/3471/3472. The SSB IC output is a
differential vertical current source to 7455 and its signal is
amplified and output as a vertical deflection current through the
vertical yoke coil.
IC 7455 has a separate flyback supply (on its VFB pin) which is
tapped from the positive portion of the heater voltage. The
flyback heater voltage charges 2461 via 6476/3487 and is
clamped by 6458.
The vertical scanning voltage (on pin V-OUT of 7455) varies
between +13V and -14V.
Components 3466/2468 are for pole-zero compensation
purposes and suppress oscillation tendencies.
Components 3467/3468 suppress horizontal coupling, and
also suppress noise.
Components 3459/6459 are part of the circuit which protects
the CRT tube from burning in, in case someone accidentally
unplugs the vertical yoke or disconnects the power supply of
7455. Without this protection, the picture tube neck may be
