Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
Index of this chapter:
2.1 Safety Instructions
2.2 Warnings
2.3 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.
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 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.
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.
•Manufactured under license from Dolby Laboratories.
“Dolby”, “Pro Logic” and the “double-D symbol”, are
trademarks of Dolby Laboratories.
2.3.2Schematic Notes
•All resistor values are in ohms, and the value multiplier is
often used to indicate the decimal point location (e.g. 2K2
indicates 2.2 kohm).
•Resistor values with no multiplier may be indicated with
either an "E" or an "R" (e.g. 220E or 220R indicates 220
ohm).
•All capacitor values are given in micro-farads (μ= x10
nano-farads (n= x10
•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.
2.3.3BGA (Ball Grid Array) ICs
Introduction
For more information on how to handle BGA devices, visit this

not available for all regions). After login, select “Magazine”,
then go to “Repair downloads”. Here you will find Information
on how to deal with BGA-ICs.

), or pico-farads (p= x10
-12
-6
),
).
2.2W arnings
•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 the danger of a
circuit becoming unstable.
2.3Notes
2.3.1 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
BGA Temperature Profiles
For BGA-ICs, you must use the correct temperature-profile,
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 "Repair downloads".
For additional questions please contact your local repair help
desk.
2.3.4Lead-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 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 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.

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.
AG is Bruges), 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 2006 week 17). The 6 last digits contain the
serial number.
Figure 2-1 Serial number (example)
2.3.6Board 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!
2.3.7NVM content
If the processor NVM IC is replaced or initialised, the Model
Number, Serial Number, and SSB Code number must be rewritten to the NVM. ComPair will foresee in a possibility to do
this.
2.3.8Practical 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.

The foam bars (order code 3122 785 90580 for two pieces) can
be used for all types and sizes of Flat TVs. See figure “Foam
bars” for details.
Sets with a display of 42" and larger, require four foam bars [1].
Ensure that the foam bars are always supporting the cabinet
and never only the display.
Caution: Failure to follow these guidelines can seriously
damage the display!
By laying the TV face down on the (ESD protective) foam bars,
a stable situation is created to perform measurements and
alignments. By placing a mirror under the TV, you can monitor
the screen.

5.1Test Points
In the chassis schematics and layout overviews, the test points
(Fxxx) are mentioned. In the schematics, test points are
indicated with a rectangular box around “Fxxx” or “Ixxx”, in the
layout overviews with a “half-moon” sign.
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.
5.2Service Modes
The Service Mode feature is split into four parts:
•Service Default Mode (SDM).
•Service Alignment Mode (SAM).
•Customer Service Mode (CSM) and Digital Customer
Service Mode (DCSM).
•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
was 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 (D)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).
5.2.1General
Some items are applicable to all Service Modes or are general.
These are listed below.
Life Timer
During the life time cycle of the TV set, a timer is kept. It counts
the normal operation hours (not the Stand-by hours). The
actual value of the timer is displayed in SDM and CSM in a
decimal value. Every two soft-resets increase the hour by +1.
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: “AAAABCD X.YY”, where:
•AAAA is the chassis name: LC71 for analogue range (nonDVB), LC72 for digital range (DVB).
•B is the region indication: E= Europe, A= AP/China, U=
NAFTA, L= LATAM.
•C is the display indication: L= LCD, P= Plasma.
•D is the language/feature indication: 1= standard, H=
1080p full HD.
•X is the main version number: this is updated with a major
change of specification (incompatible with the previous
software version). Numbering will go from 1 - 9 and A - Z.
– 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 and “xxx”,
where “xxx” is a 3 digit decimal value of the panel type: see
column “Panel Code” in table “Option Codes OP1...OP7” (ch.
8), or 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.

During this algorithm, the NVM-content must be filtered,
because several items in the NVM are TV-related and not SSBrelated (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.

•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/

5.2.4 Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and
information on the TV’s operation settings. A call centre can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set. This helps them to diagnose
problems and failures in the TV before making a service call.
The CSM is a read-only mode; therefore, modifications are not
possible in this mode.
Specifications
•Ignore “Service unfriendly modes”.
•Line number for every line (to make CSM language
independent).
•Set the screen mode to full screen (all contents on screen
are viewable).
•After leaving the Customer Service Mode, the original
settings are restored.
•Possibility to use “CH+” or “CH-” for channel surfing, or
enter the specific channel number on the RC.
How to Activate
To activate CSM, press the following key sequence on the

5.3Service Tools
5.3.1ComPair
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).

Service Modes, Error Codes, and Fault Finding
EN 21LC7.5E LA5.
5.4Error 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 protection.
•Failing I2C device.
•General I2C error.
•SDRAM failure.
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 may never lead to a
deadlock situation. This means that it must always be
diagnosable (e.g. error buffer via OSD or blinking LED
procedure, ComPair to read from the NVM).
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.
Example: In case of a failure of the I2C bus (CAUSE), the error
code for a “General I2C failure” and “Protection errors” is
displayed. The error codes for the single devices (EFFECT) is
not displayed. All error codes are stored in the same error
buffer (TV’s NVM) except when the NVM itself is defective.
5.4.2How to Read the Error Buffer
You can read the error buffer in 3 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 “The Blinking LED Procedure”.
•Via ComPair.
5.4.3 Error Codes
In case of non-intermittent faults, write down the errors present
in the error buffer and clear the error buffer before you begin
the repair. This ensures that old error codes are no longer
present.
If possible, check the entire contents of the error buffer. In
some situations, an error code is only the result of another error
and not the actual cause of the problem (for example, a fault in
the protection detection circuitry can also lead to a protection).

Notes
1. Some of the error codes reported are depending on the
option code configurations.
2. This error means: no I2C device is responding to the
particular I2C bus. Possible causes: SCL/SDA shorted to
GND, SCL shorted to SDA, or SCL/SDA open (at uP pin).
The internal bus of the Trident platform should not cause
the entire system to halt as such an error can be reported.
5.4.4How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
•By using the CLEAR command in the SAM menu:
– To enter SAM, press the following key sequence on the
remote control transmitter: “062596” directly followed
by the OSD/i+ button (do not allow the display to time
out between entries while keying the sequence).
– Make sure the menu item CLEAR is selected. Use the
MENU UP/DOWN buttons, if necessary.
– Press the MENU RIGHT button to clear the error
buffer. The text on the right side of the “CLEAR” line will
change from “CLEAR?” to “CLEARED”
•If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.

Service Modes, Error Codes, and Fault Finding
Note: If you exit SAM by disconnecting the mains from the
television set, the error buffer is not reset.
5.5The Blinking LED Procedure
5.5.1Introduction
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 RC5
command terminates the sequence. Error code LED blinking is
in red colour.
Example (2): the content of the error buffer is “12 9 6 0 0”
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
5.6Software Upgrading
In this chassis, three SW “stacks” are used:
•TV mains SW (processor and processor NVM).
•Digital TV SW (IBO Zapper).
5.6.1TV Main SW Upgrade
For instructions on how to upgrade the TV Main software, refer
to ComPair.
5.6.2“Digital TV” Software Upgrade
How to Upgrade Philips “Digital TV” Software (IBO Zapper):
Preparation of the Memory Device for Software Upgrade
For the procedure you will require:
1. A personal computer with web browsing capability.
2. An archive utility that supports the ZIP-format (e.g. Winzip
for Windows).
3. A CompactFlash PC Card Adapter (Type II).
4. A CompactFlash (Type I) portable memory card for
insertion into the PC Card Adapter. Philips recommends
using Compact Flash (CF) portable memory cards with
their respective PC Card Adapters (Sandisk or Kingston)
with memory sizes of up to 256MB. Philips does not
guarantee that other types of portable memory cards and
their respective PC Card Adapters, including multi-card PC
Card Adapters work on Philips Digital TV.
Note: Only FAT16-formatted portable memory is
supported. NTFS & FAT32 are not supported.
Copying of Software Image Files to the Flash Device
Copy the appropriate “FCL.img” and “IBOZ.img” to the root
directory of the flash device.
Additionally, the entire error buffer is displayed when Service
Mode “SDM” is entered. In case the TV set is in protection or
Stand-by: The blinking LED procedure sequence (as in SDMmode in normal operation) must be triggered by the following
RC sequence: “MUTE” “062500” “OK”.
In order to avoid confusion with RC5 signal reception blinking,
this blinking procedure is terminated when a RC5 command is
received.
To erase the error buffer, the RC command “MUTE” “062599 “OK” can be used.
Verifying the Current Version of the TV Software
Before you start the software upgrade procedure, it is advised
to check what the current TV software is. The current TV
software version can be seen in the “System software” menu.
1. First press the “A/D” key and then the “DIGITAL MENU”
key on the remote controller to access the “Setup” menu.
2. Access the “Information” menu.
3. Access the “Current software version” menu.
Example:
The menu shows “IdtvZapper_HW260.256_SW2.0.24”. This
means that the hardware version is “260.256” and the software
version is “2.0.24”.

Service Modes, Error Codes, and Fault Finding
Software Upgrade Procedure
1. Power ON your TV with the power switch at the side of the
TV. Put your TV ON by using the remote controller if the TV
is in Stand-by.
2. Make sure that it is in “Digital” mode (via “A/D” button).
3. Make sure that your TV is not in Stand-by. Power OFF your
TV with the power switch of the TV.
4. Remove the Conditional Access Module (if any) from the
CI-slot.
5. Insert the PC Card Adapter with the portable memory card
containing the software upgrade files.
6. Switch ON your TV with the power switch at the side of the
TV.
7. At start-up, the TV will scan the CI slot until it finds the
update content. The TV will automatically go to the
upgrade mode. After a few seconds it will display the status
of the upgrade procedure.
Warnings:
Do NOT remove the memory card or the PC card adapter
during the software upgrade procedure.
In case of a power drop during the upgrade procedure, don’t
remove the portable memory from the TV. The TV will continue
the upgrade as soon as the power comes back.
Example: At start-up of the TV, the current software is erased.
EN 23LC7.5E LA5.

Figure 5-15 Upgrade ready
When the software upgrade has been successful, switch OFF
the TV, remove the PC Card Adapter, and restart the TV with
the Power switch at the side of the TV.
The TV will now start up with the new software.
Verifying that the Software Has Been Upgraded
Successfully
Verify that the software is upgraded to the new version by
following the procedure outlined in the section “Verifying the
current version of the TV software”.
G_16221_002.eps

The TV will reset and the screen will go blank, after a few
seconds a dialogue box will occur to inform you that the current
module inserted in the CI slot is not recognized. This is normal
as the slot only recognizes a Conditional Access Module during
normal operation.
Example: The following dialogue box will appear after the TV is
upgraded successfully:

Service Modes, Error Codes, and Fault Finding
5.7Fault 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.
5.7.1 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 the NVM settings 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.
Table 5-3 NVM editor overview
HexDecDescription
.ADR0x000A10Existing value
.VAL0x00000New value
.StoreStore?
5.7.2 Load Default NVM Values
Alternative method (1):
1. Go to SAM.
2. Select NVM Editor.
3. Select ADR (address) to 1 (dec).
4. Change the VAL (value) to 170 (dec).
5. Store the value.
6. Do a hard reset to make sure new default values took
place.
Alternative method (2):
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.
5.7.3Start-up/Shut-down Flowcharts
Important note for DVB sets:
•When you put a DVB set into Stand-by mode with an RC,
the set will go to “Semi Stand-by” mode for 5 minutes. This,
to facilitate “Off the Air download” (OAD). If there is no
activity within these 5 minutes, the set will switch to Standby mode. In “Semi Stand-by” mode, the LCD backlight and
Audio Amplifier are turned “off” but other circuits still work
as normal. The customer might think the set is in Stand-by.
However, in real Stand-by mode, only the uP and the NVM
are alive and all other circuits are switched “off”.
•If you press the mains switch at the local key board in a
DVB set, the set will switch to Stand-by mode.
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 "Standby" or "Off" situation).
2. Short-circuit the SDM jumpers on the SSB (keep short
circuited).
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 “on” or blue LED
is blinking.
When the downloading has completed successfully, the set
should be into Stand-by, i.e. red LED on.
On the next pages you will find start-up and shut-down
flowcharts, which might be helpful during fault finding.

8.1General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
•Power supply voltage (depends on region):
– AP-NTSC: 120 V
– AP-PAL-multi: 120 - 230 V
– EU: 230 V
– LATAM-NTSC: 120 - 230 V
– US: 120 V
•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.

8.3Software Alignments
With the software alignments of the Service Alignment Mode
(SAM) the Tuner and RGB settings can be aligned.
To store the data: Use the RC button “Menu” to switch to the
main menu and next, switch to “Stand-by” mode.
8.3.1Tuner Adjustment (RF AGC Take Over Point)
Purpose: To keep the tuner output signal constant as the input
signal amplitude varies.
The LC7.5x chassis comes with the TD1316AF tuner. No
alignment is necessary, as the AGC alignment is done
automatically (standard value: “15”), even during analogue
reception.
8.3.2RGB Alignment
Before alignment, choose “TV MENU” -> “Picture” and set:
•“Brightness” to “50”.
•“Colour” to “50”.
•“Contrast” to “100”.
8.2Hardware 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.

•Select “RGB Align.” -> “White Tone” and choose a colour
temperature.
•Use a 100% white screen as input signal and set the
following values:
– All “White point” values initial to “256”.
– All “BlackL Offset” values to “0”.
In case you have a colour analyser:
•Measure with a calibrated (phosphor- independent) colour
analyser (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 “256”) by means of
decreasing the value of one or two other white points to the
correct x,y coordinates (see table “White D alignment
values”). Tolerance: dx: ± 0.004, dy: ± 0.004.
•Repeat this step for the other colour 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.

If you do not have a colour analyser, 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.
•Select “RGB Align.” -> “BlackL Offset” and choose a colour.
•Set all “BlackL Offset” values to “0”.
•When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.
Note: For models with “Pixel Plus”, the “Black Offset” (black
level offset) should NOT be changed in SAM. These offset
values of RGB should be set to “0”, and should NOT be
adjusted. Any adjustment of these values will affect the low
light white balance.
ADC YPbPr Gray Scale Alignment
When the grey scale is not correct, use this alignment:
•Activate SAM.
•Select “NVM Editor”.
•Enter address “26(dec)” (ADR).
•Set value (VAL) to “197(dec) ± 25”.
•Store (STORE) the value.
8.4Option Settings
8.4.1Introduction
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.
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).
8.4.2 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 in table “Option Codes OP1...OP7“ below.
How to Change Options Codes
An option code (or “option byte”) represents eight different
options (bits). When you change these numbers directly, you
can set all options very quickly. All options are controlled via
seven option bytes (OP1... OP7).
Activate SAM and select “Options”. Now you can select the
option byte (OP1.. OP7) with the CURSOR UP/ DOWN keys,
and enter the new 3 digit (decimal) value. For the correct
factory default settings, see the next table “Option codes
OP1...OP7“. For more detailed information, see the second
table “Option codes at bit level“. If an option is set (value “1”), it
represents a certain decimal value.
When all the correct options (bits) are set, the sum of the
decimal values of each Option Byte (OP) will give the option
code.
Below find an overview of the Option Codes on bit level.

9.1.1SSB Cell Layout
9.1Introduction
The LC7.5x chassis (development name “LC07S”) is a digital
derivative from the digital LC7.2x chassis (development name
“LC07”). It covers screen sizes of 32" and 42" with a new styling
called “SuperNova” and 52" with existing styling “ME7”.
Some delta’s with respect to the LC7.2x chassis are:
•Video: Video processing is performed by the Trident video
processor SVP WX86 (item 7C01) which outputs a signal
of 1080p (no additional 1080p panel needed), introduces
Digital Natural Motion (DNM) and supports MPEG Artifact
Reduction.
•AmbiLight: FPGA-based AmbiLight controller integrated on
SSB (no additional AmbiLight panel needed).
•Audio: introducing BBE
intelligibility and music performance with an additional
subwoofer.
•HDMI: Additional HDMI connector with on-board switch
has been added.
•On-board DC-DC converters: DC-DC-converters onboard the SSB have been changed.
For (other) features of the chassis, please refer to the
LC7.2E LA Service Manual.

9.2LCD Power Supply
The Power Supply Unit (PSU) in this chassis is a buy-in and is
a black-box for Service. When defective, a new panel must be
ordered and the defective panel must be returned for repair,
unless the main fuse of the unit is broken. Always replace the
fuse with one of the correct specifications! This part is
commonly available in the regular market.
Three different PSU can be used in this chassis:
•32" sets use a “Delta” PSU
•42" sets use a “PPS” (Philips Power Solutions) PSU
•52" sets use a “Delta” PSU.
Figure “Overview of PSU connectivity” shows the connectivity
of the Power Supply Unit with the other panels in the set.

Figure 9-7 Block diagram video processing
“Block diagram video processing” shows the input and output
signals to and from the Trident Video Processor.
During analogue reception, a CVBS signal coming from the
analogue front-end is fed to the video processor via pin
CVBS1. During digital reception, the video signal coming from
the MPEG decoder (MOJO) is fed to the video processor via
pins FS1, PC_B, PC_G and PC_R.
The video processor also interfaces the SCART1 & 2 input,
side AV, EXT4 (HD where applicable) and HDMI1 & 2 and Side
HDMI input. Through the SCART1 & 2 connectors, a monitor
output is foreseen.

Figure 9-8 HDMI implementation
The implementation supports:
•Three HDMI input connectors to the TV via “HDMI rear” as
“HDMI1”, “HDMI2” and “HDMI3”.
•One HDMI input connector to the TV via “HDMI side” as
“Side HDMI”.
•All EDID is stored in the internal EEPROM which is
integrated inside the Sil9185 multiplexer and Sil9181 buffer
IC.
2
S output for connection to low-cost DACs at a frequency
•I
of 32 to 192 kHz.
•Pre-programmed HDCP keys providing the highest level of
security and simplicity during manufacturing.
When the HDMI receiver Sil9125 receives either RGB or
YCbCr 4:2:2 input signals, it will convert these signals to 24-36bit YCbCr 4:4:4 output signals. When it receives an YCbCr
4:4:4 input signal, it will just bypass this signal to the Trident
WX68 video processor.
Refer to figures “HDMI signal flow diagram” and “HDMI
interface to Video Processor” for details.
