3. Precautions, Notes, and Abbreviation List
Index of this chapter:
3.1 Safety Instructions
3.2 Warnings
3.3 Notes
3.4 Abbreviation List
3.1 Safety 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.
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/AC Power lead for
external damage.
• Check the strain relief of the Mains/AC Power cord for
proper function.
• 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 MΩ and 12 MΩ.
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.
3.2 Warnings
• 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.
• 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.
3.3 Notes
3.3.1 General
• 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 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.
3.3.2 Schematic Notes
• All resistor values are in ohms, and the value multiplier is
often used to indicate the decimal point location (e.g. 2K2
indicates 2.2 kΩ).
• Resistor values with no multiplier may be indicated with
either an “E” or an “R” (e.g. 220E or 220R indicates 220 Ω).
• All capacitor values are given in micro-farads (μ=× 10
-6
),
nano-farads (n =× 10
-9
), or pico-farads (p =× 10
-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 on the Philips
Spare Parts Web Portal.
3.3.3 Spare Parts
For the latest spare part overview, consult your Philips Spare
Part web portal.
3.3.4 BGA (Ball Grid Array) ICs
Introduction
For more information on how to handle BGA devices, visit this
URL: http://www.atyourservice-magazine.com
. Select
“Magazine”, then go to “Repair downloads”. Here you will find
Information on how to deal with BGA-ICs.
BGA Temperature Profiles
For BGA-ICs, you must use the correct temperature-profile.
Where applicable and available, this profile is added to the IC
Data Sheet information section in this manual.
3.3.5 Lead-free Soldering
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
• Use only lead-free soldering tin. 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 stabilize 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 stabilized 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
clear the solder-joint from old tin and re-solder with new tin.
3.3.6 Alternative BOM identification
It should be noted that on the European Service website,
“Alternative BOM” is referred to as “Design variant”.
Precautions, Notes, and Abbreviation List
EN 5L11M1.1L LA 3.
2011-Apr-29
The third digit in the serial number (example:
AG2B0335000001) indicates the number of the alternative
B.O.M. (Bill Of Materials) that has been used for producing the
specific TV set. In general, it is possible that the same TV
model on the market is produced with e.g. two different types
of displays, coming from two different suppliers. This will then
result in sets which have the same CTN (Commercial Type
Number; e.g. 28PW9515/12) but which have a different B.O.M.
number.
By looking at the third digit of the serial number, one can
identify which B.O.M. is used for the TV set he is working with.
If the third digit of the serial number contains the number “1”
(example: AG1B033500001), then the TV set has been
manufactured according to B.O.M. number 1. If the third digit is
a “2” (example: AG2B0335000001), then the set has been
produced according to B.O.M. no. 2. This is important for
ordering the correct spare parts!
For the third digit, the numbers 1...9 and the characters A...Z
can be used, so in total: 9 plus 26= 35 different B.O.M.s can be
indicated by the third digit of the serial number.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 1 and 2 refer to the production centre (e.g.
SN is Lysomice, RJ is Kobierzyce), digit 3 refers to the B.O.M.
code, digit 4 refers to the Service version change code, digits 5
and 6 refer to the production year, and digits 7 and 8 refer to
production week (in example below it is 2010 week 10 / 2010
week 17). The 6 last digits contain the serial number.
Figure 3-1 Serial number (example)
3.3.7 Board Level Repair (BLR) or Component Level Repair
(CLR)
If a board is defective, consult your repair procedure to decide
if the board has to be exchanged or if it should be repaired on
component level.
If your repair procedure says the board should be exchanged
completely, do not solder on the defective board. Otherwise, it
cannot be returned to the O.E.M. supplier for back charging!
3.3.8 Practical Service Precautions
• It makes sense to avoid exposure to electrical shock.
While some sources are expected to have a possible
dangerous impact, others of quite high potential are of
limited current and are sometimes held in less regard.
• Always respect voltages. While some may not be
dangerous in themselves, they can cause unexpected
reactions 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.

4.2 Service Positions
For easy servicing of a TV set, the set should be put face down
on a soft flat surface, foam buffers or other specific workshop
tools. Ensure that a stable situation is created to perform
measurements and alignments. When using foam bars take
care that these always support the cabinet and never only the
display. Caution: Failure to follow these guidelines can
seriously damage the display!
Ensure that ESD safe measures are taken.

Index of this chapter:
5.1 Test Points
5.2 Service Modes
5.3 Service Tools
5.4 Error Codes
5.5 The Blinking LED Procedure
5.6 Fault Finding and Repair Tips
5.7 Software Upgrading
5.1 Test Points
In the chassis schematics and layout overviews, the test points
are mentioned. In the schematics and layouts, test points are
indicated with “Fxxx” or “Ixxx”.
As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope. Several key ICs are
capable of generating test patterns, which can be controlled via
ComPair. In this way it is possible to determine which part is
defective.
Perform measurements under the following conditions:
• Service Default Mode.
• Video: Colour bar signal.
• Audio: 3 kHz left, 1 kHz right.
5.2 Service Mode s
The Service Mode feature is split into four parts:
• Service Default Mode (SDM).
• Service Alignment Mode (SAM).
• Customer Service Mode (CSM).
• Computer Aided Repair Mode (ComPair).
SDM and SAM offer features, which can be used by the Service
engineer to repair/align a TV set. Some features are:
• A pre-defined situation to ensure measurements can be
made under uniform conditions (SDM).
• Activates the blinking LED procedure for error identification
when no picture is available (SDM).
• The possibility to overrule software protections when SDM
is entered via the Service pins.
• Make alignments (e.g. White Tone), (de)select options,
enter options codes, reset the error buffer (SAM).
• Display information (“SDM” or “SAM” indication in upper
right corner of screen, error buffer, software version,
operating hours, options and option codes, sub menus).
The CSM is a Service Mode that can be enabled by the
consumer. The CSM displays diagnosis information, which the
customer can forward to the dealer or call centre. In CSM
mode, “CSM”, is displayed in the top right corner of the screen.
The information provided in CSM and the purpose of CSM is to:
• Increase the home repair hit rate.
• Decrease the number of nuisance calls.
• Solved customers' problem without home visit.
ComPair Mode is used for communication between a computer
and a TV on I2C /UART level and can be used by a Service
engineer to quickly diagnose the TV set by reading out error
codes, read and write in NVMs, communicate with ICs and the
uP (PWM, registers, etc.), and by making use of a fault finding
database. It will also be possible to up and download the
software of the TV set via I2C with help of ComPair. To do this,
ComPair has to be connected to the TV set via the ComPair
connector, which will be accessible through the rear of the set
(without removing the rear cover).
5.2.1 General
Next items are applicable to all Service Modes or are general.
Life Timer
During the life time cycle of the TV set, a timer is kept (called
“Op. Hour”). It counts the normal operation hours (not the
Stand-by hours). The actual value of the timer is displayed in
SDM and SAM in a decimal value. Every two soft-resets
increase the hour by +1. Stand-by hours are not counted.
Software Identification, Version, and Cluster
The software ID, version, and cluster will be shown in the main
menu display of SDM, SAM, and CSM.
The screen will show: “AAAAAAB-XX.YY”, where:
• AAAAAA is the chassis name: L11M11.
• B is the region indication: E= Europe, A= AP/China, U=
NAFTA, L= LATAM.
• XX is the main version number: this is updated with a major
change of specification (incompatible with the previous
software version). Numbering will go from 01 - 99 and AA -
ZZ.
– If the main version number changes, the new version
number is written in the NVM.
– If the main version number changes, the default
settings are loaded.
• YY is the sub version number: this is updated with a minor
change (backwards compatible with the previous versions)
Numbering will go from 00 - 99.
– If the sub version number changes, the new version
number is written in the NVM.
– If the NVM is fresh, the software identification, version,
and cluster will be written to NVM.
Display Option Code Selection
When after an SSB or display exchange, the display option
code is not set properly, it will result in a TV with “no display”.
Therefore, it is required to set this display option code after
such a repair.
To do so, press the following key sequence on a standard RC
transmitter: “062598” directly followed by MENU/HOME and
“xxx”, where “xxx” is a 3 digit decimal va
lue of
the panel type,
see sticker on the side/bottom of the cabinet. When the value
is accepted and stored in NVM, the set will switch to Stand-by,
to indicate that the process has been completed.
Figure 5-1 Location of Display Option Code sticker
During this algorithm, the NVM-content must be filtered,
because several items in the NVM are TV-related and not SSB-
related (e.g. Model and Prod. S/N). Therefore, “Model” and
“Prod. S/N” data is changed into “See Type Plate”.
In case a call centre or consumer reads “See Type Plate” in
CSM mode, he needs to look to the side/bottom sticker to
identify the set, for further actions.

5.2.2 Service Default Mode (SDM)
Purpose
Set the TV in SDM mode in order to be able to create a pre-
defined setting for measurements to be made. In this platform,
a simplified SDM is introduced (without protection override and
without tuning to a predefined frequency).
Specifications
• Set linear video and audio settings to 50%, but volume to
25%. Stored user settings are not affected.
• Set Smart Picture to “Game”.
• Set Smart Sound to “Standard”.
• Tune channel to:
- for analogue SDM: channel 3 (61.25 MHz)
- for digital SDM: channel 26 (545.143 MHz).
• For digital SDM: set PID default from the stream.
• All service-unfriendly modes (if present) are disabled, since
they interfere with diagnosing/repairing a set. These
service unfriendly modes are:
– (Sleep) timer.
– Blue mute/Wall paper.
– Auto switch “off” (when there is no “ident” signal).
– Hotel or hospital mode.
– Child lock or parental lock (manual or via V-chip).
– Skipping, blanking of “Not favourite”, “Skipped” or
“Locked” presets/channels.
– Automatic storing of Personal Preset or Last Status
settings.
– Automatic user menu time-out (menu switches back/
OFF automatically.
– Auto Volume levelling (AVL).
How to Activate
To activate analogue SDM, use one of the following methods:
• Press the following key sequence on the RC transmitter:
“062596” directly followed by the MENU button.
• Short one of the “Service” pads on the TV board during cold
start (see Figure 5-2
). Then press the mains button
(remove the short after start-up).
Caution: When doing this, the service-technician must
know exactly what he is doing, as it could damage the
television set.
To activate digital SDM:
• Press the following sequence on the RC transmitter:
“062593” directly followed by the MENU button.
Figure 5-2 Service pads (SSB component side)

After activating SDM, the following items are displayed, with
“SDM” in the upper right corner of the screen to indicate that the
television is in Service Default Mode.
Menu items and explanation:
• xxxxx: Operating hours (in decimal).
• AAAAAAB-XX.YY: See paragraph Software
Identification, Version, and Cluster for the SW name
definition.
• ERR: Shows all errors detected since the last time the
buffer was erased in format <xxx> <xxx> <xxx> <xxx>
<xxx> (five errors possible).
• OP: Used to read-out the option bytes. Ten codes (in two
rows) are possible.
How to Navigate
As this mode is read only, there is not much to navigate. To
switch to other modes, use one of the following methods:
• Command MENU from the user remote will enter the
normal user menu (brightness, contrast, color, etc...) with
“SDM” OSD remaining, and pressing MENU key again will
return to the last status of SDM again.
• To prevent the OSD from interfering with measurements in
SDM, command “OSD” or “i+” (“STATUS” or “INFO” for
NAFTA and LATAM) from the user remote will toggle the
OSD “on/off” with “SDM” OSD remaining always “on”.
• Press the following key sequence on the remote control
transmitter: “062596” directly followed by the INFO[i+]/OK
button to switch to SAM (do not allow the display to time out
between entries while keying the sequence).
How to Exit
Switch the set to Stand-by by
• pressing the standby button on the remote control
transmitter or on the television set, or
• via a standard RC-transmitter by keying the “00” sequence.
If you switch the television set “off” by removing the mains (i.e.,
unplugging the television), the television set will remain in SDM
when mains is re-applied, and the error buffer is not cleared.
The error buffer will only be cleared when the “clear” command
is used in the SAM menu.
Note:
• If the TV is switched “off” by a power interrupt while in SDM,
the TV will show up in the last status of SDM menu as soon
as the power is supplied again. The error buffer will not be
cleared.
• In case the set is accidentally in Factory mode (with an “F”
displayed on the screen), pressing and holding “VOL-“
button for 5 seconds and then followed by pressing and
holding the “CH-” button for another 5 seconds should exit
the Factory mode.

5.3 Service Tools
5.3.1 ComPair
Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips
Consumer Electronics products. and offers the following:
1. ComPair helps you to quickly get an understanding on how
to repair the chassis in a short and effective way.
2. ComPair allows very detailed diagnostics and is therefore
capable of accurately indicating problem areas. You do not
have to know anything about I2C or UART commands
yourself, because ComPair takes care of this.
3. ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the uP
is working) and all repair information is directly available.
4. ComPair features TV software up possibilities.
Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The (new) ComPair II interface box is connected to the PC via
an USB cable. For the TV chassis, the ComPair interface box
and the TV communicate via a bi-directional cable via the
service connector(s).
How to Connect
This is described in the ComPair chassis fault finding database.
Figure 5-3 ComPair II interface connection
Caution: It is compulsory to connect the TV to the PC as
shown in the picture above (with the ComPair interface in
between), as the ComPair interface acts as a level shifter. If
one connects the TV directly to the PC (via UART), ICs will be
blown!
How to Order
ComPair II order codes:
• ComPair II interface: 3122 785 91020.
• ComPair UART interface cable: 3138 188 75051.
• Program software can be downloaded from the Philips
Service web portal.
Note: For this chassis, “Pgammar” and “T-con NVM”
programming (VCOM alignment) are added to ComPair.
Additional cables for VCOM Alignment
•ComPair/I

C interface cable: 3122 785 90004.
• ComPair/VGA adapter cable: 9965 100 09269.
5.4 Error Codes
5.4.1 Introduction
Error codes are required to indicate failures in the TV set. In
principle a unique error code is available for every:
• Activated (SW) protection.
• Failing I
2
C device.
• General I
2
C error.
The last five errors, stored in the NVM, are shown in the
Service menu’s. This is called the error buffer.
The error code buffer contains all errors detected 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 displayed at the left side and all other errors shift one
position to the right.
An error will be added to the buffer if this error differs from any
error in the buffer. The last found error is displayed on the left.
An error with a designated error code never leads to a
deadlock situation. It must always be diagnosable (e.g. error
buffer via OSD or blinking LED or via ComPair).
In case a failure identified by an error code automatically
results in other error codes (cause and effect), only the error
code of the MAIN failure is displayed.

5.4.2 How to Read the Error Buffer
You can read the error buffer in three ways:
• On screen via the SAM/SDM/CSM (if you have a picture).
Example:
– ERROR: 0 0 0 0 0 : No errors detected
– ERROR: 6 0 0 0 0 : Error code 6 is the last and only
detected error
– ERROR: 9 6 0 0 0 : Error code 6 was detected first and
error code 9 is the last detected (newest) error
• Via the blinking LED procedure (when you have no
picture). See paragraph 5.5 The Blinking LED Procedure
.
•Via ComPair.
5.4.3 Error codes
The “layer 1” error codes are pointing to the defective board.
They are triggered by LED blinking when CSM is activated. In
the LC10 platform, only two boards are present: the SSB and
the PSU/IPB, meaning only the following layer 1 errors are
defined:
• 2: SSB
• 3: IPB/PSU
•4: Display
Table 5-1 Error code table
5.4.4 How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
• By using the CLEAR command in the SAM menu:
• By using the following key sequence on the remote control
transmitter: “062599” directly followed by the OK button.
• If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.
Note: If you exit SAM by disconnecting the mains from the
television set, the error buffer is not reset.
5.5 The Blinking LED Proc edure
5.5.1 Introduction
The software is capable of identifying different kinds of errors.
Because it is possible that more than one error can occur over
time, an error buffer is available, which is capable of storing the
last five errors that occurred. This is useful if the OSD is not
working properly.
Errors can also be displayed by the blinking LED procedure.
The method is to repeatedly let the front LED pulse with as
many pulses as the error code number, followed by a period of
1.5 seconds in which the LED is “off”. Then this sequence is
repeated.
Example (1): error code 4 will result in four times the sequence
LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After
this sequence, the LED will be “off” for 1.5 seconds. Any RC
command terminates the sequence. Error code LED blinking is
in red color.
Example (2): the content of the error buffer is “129600”
After entering SDM, the following occurs:
• 1 long blink of 5 seconds to start the sequence,
• 12 short blinks followed by a pause of 1.5 seconds,
• 9 short blinks followed by a pause of 1.5 seconds,
• 6 short blinks followed by a pause of 1.5 seconds,
• 1 long blink of 1.5 seconds to finish the sequence,
• The sequence starts again with 12 short blinks.
5.5.2 Displaying the Entire Error Buffer
Additionally, the entire error buffer is displayed when Service
Mode “SDM” is entered.
5.6 Fault Finding and Repair Tips
Notes:
• It is assumed that the components are mounted correctly
with correct values and no bad solder joints.
• Before any fault finding actions, check if the correct
options are set.
5.6.1 NVM Editor
In some cases, it can be convenient if one directly can change
the NVM contents. This can be done with the “NVM Editor” in
SAM mode. With this option, single bytes can be changed.
Caution:
• Do not change these, without understanding the
function of each setting, because incorrect NVM
settings may seriously hamper the correct functioning
of the TV set!
• Always write down the existing NVM settings, before
changing the settings. This will enable you to return to the
original settings, if the new settings turn out to be incorrect.
5.6.2 Load Default NVM Values
It is possible to download default values automatically into the
NVM in case a blank NVM is placed or when the NVM first 20
address contents are “FF”. After the default values are
downloaded, it is possible to start-up and to start aligning the
TV set. To initiate a forced default download the following
action has to be performed:
1. Switch “off” the TV set with the mains cord disconnected
from the wall outlet (it does not matter if this is from “Stand-
by” or “Off” situation).
2. Short-circuit the SDM pads on the SSB (keep short
circuited, see Figure 5-2
).
3. Press “P+” or “CH+” on the local keyboard (and keep it
pressed).
4. Reconnect the mains supply to the wall outlet.
5. Release the “P+” or “CH+” when the set is started up and
has entered SDM.
When the downloading has completed successfully, the set will
perform a restart. After this, put the set to Stand-by and remove
the short-circuit on the SDM pads.
Alternative method:
It is also possible to upload the default values to the NVM with
ComPair in case the SW is changed, the NVM is replaced with
a new (empty) one, or when the NVM content is corrupted.
After replacing an EEPROM (or with a defective/no EEPROM),
default settings should be used to enable the set to start-up and
allow the Service Default Mode and Service Alignment Mode to
be accessed.

5.7 Software Upgrading
5.7.1 I ntroduction
It is possible for the user to upgrade the main software via the
USB port. This allows replacement of a software image in a
stand alone set. A description on how to upgrade the main
software can be found in the DFU or on the Philips website.
5.7.2 Main Software Upgrade
Automatic Software Upgrade
In “normal” conditions, so when there is no major problem with
the TV, the main software and the default software upgrade
application can be upgraded with the “autorun.upg” (FUS part
in the one-zip file). This can also be done by the consumers
themselves, but they will have to get their software from the
commercial Philips website or via the Software Update
Assistant in the user menu (see DFU). The “autorun.upg” file
must be placed in the root of your USB stick.
How to upgrade:
1. Copy the “autorun.upg” file to the root of an USB stick.
2. Insert the USB stick in the side I/O while the set is “on”.
The TV will prompt an upgrade message. Press “Update”
to continue, after which the upgrading process will start. As
soon as the programming is finished, the set must be
restarted.
In the “Setup” menu you can check if the latest software is
running.

6.6 Option Settings
Note: Figures below can deviate slightly from the actual
situation, due to the different set executions.
General: The Service Default Mode (SDM) and Service
Alignment Mode (SAM) are described in chapter 5. Menu
navigation is done with the CURSOR UP, DOWN, LEFT or
RIGHT keys of the remote control transmitter.
6.1 General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
• Power supply voltage (depends on region):
– AP-NTSC: 120 V
AC
or 230 V
AC
/ 50 Hz (± 10%).
– AP-PAL-multi: 120 - 230 V
AC
/ 50 Hz (± 10%).
– EU: 230 V
AC
/ 50 Hz (± 10%).
– LATAM-NTSC: 120 - 230 V
AC
/ 50 Hz (± 10%).
– US: 120 V
AC
/ 60 Hz (± 10%).
• Connect the set to the mains via an isolation transformer
with low internal resistance.
• Allow the set to warm up for approximately 15 minutes.
• Measure voltages and waveforms in relation to correct
ground (e.g. measure audio signals in relation to
AUDIO_GND).
Caution: It is not allowed to use heatsinks as ground.
• Test probe: Ri > 10 Mohm, Ci < 20 pF.
• Use an isolated trimmer/screwdriver to perform
alignments.
6.2 Hardware Alignments
There are no hardware alignments foreseen for this chassis,
but below find an overview of the most important DC voltages
on the SSB. These can be used for checking proper functioning
of the DC/DC converters.
6.3 Software Alignments
With the software alignments of the Service Alignment Mode
(SAM) the Tuner and RGB settings can be aligned.
6.3.1 Tuner Adjustment (RF AGC Take Over Point)
Purpose: To keep the tuner output signal constant as the input
signal amplitude varies.
No alignment is necessary, as the AGC alignment is done
automatically.
6.3.2 RGB Alignment
Before alignment, set the picture as follows:
White Tone Alignment:
• Activate SAM.
• Select “RGB Align.“ and choose a color temperature.
• Use a 100% white screen as input signal and set the
following values:
– “Red BL Offset” and “Green BL Offset” to “7” (if
present).
– All “White point” values initial to “127”.
In case you have a color analyzer:
• Measure with a calibrated (phosphor- independent) color
analyzer (e.g. Minolta CA-210) in the centre of the screen.
Consequently, the measurement needs to be done in a
dark environment.
• Adjust the correct x,y coordinates (while holding one of the
White point registers R, G or B on max. value) by means of
decreasing the value of one or two other white points to the
correct x,y coordinates (see Table 6-1 White D alignment
values). Tolerance: dx: ± 0.002, dy: ± 0.002.
• Repeat this step for the other color Temperatures that need
to be aligned.
• When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.
Table 6-1 White D alignment values
If you do not have a color analyzer, you can use the default
values. This is the next best solution. The default values are
average values coming from production (statistics).
• Set the RED, GREEN and BLUE default values per
temperature according to the values in the “Tint settings”
table.
• When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.

6.5 TCON Alignment (= VCOM alignment)
New requirement for “TCON on SSB” project:
• The purpose of VCOM alignment is to obtain an equal
voltages for both Positive and Negative LC polarity. This is
important to avoid “Flicker” and “Image Sticking”.
• The P-Gamma + VCOM calibrator IC, ISL24837 is used for
VCOM adjustment.
• The adjusted VCOM data will be stored inside on-chip
memory and will be automatically recalled during each
power-up.
ComPair (see 5.3.1 ComPair
) will foresee in a possibility to do
this alignment.
6.6 Option Settings
6.6.1 Introduction
The microprocessor communicates with a large number of I
2
C
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.
Notes:
• After changing the option(s), save them with the STORE
command.
• The new option setting becomes active after the TV is
switched “off” and “on” again with the mains switch (the
EAROM is then read again).
6.6.2 How To Set Option Codes
When the NVM is replaced, all options will require resetting. To
be certain that the factory settings are reproduced exactly, you
must set all option numbers. You can find the correct option
numbers see sticker on the inside the cabinet.
How to Change Options Codes
An option code (or “option byte”) represents eight different
options (bits). All options are controlled via ten option bytes
(OP#1... OP#10).
Activate SAM and select “Options”. Now you can select the
option byte (OP#1... OP#10) with the CURSOR UP/ DOWN
keys, and enter the new 3 digit (decimal) value. For the correct
factory default settings, see the sticker inside the set.
