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

), or pico-farads (p= x10
-12
-6
),
).
2.2Warnings
•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
2.3.1General
•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
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.

Figure 4-6 Foam bars
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.
4.2.2Aluminium Stands

Figure 4-7 Aluminium stands (drawing of MkI)
The new MkII aluminium stands (not on drawing) with order
code 3122 785 90690, can also be used to do measurements,
alignments, and duration tests. The stands can be
(dis)mounted quick and easy by means of sliding them in/out
the "mushrooms". The new stands are backwards compatible
with the earlier models.
Important: For (older) FTV sets without these "mushrooms", it
is obligatory to use the provided screws, otherwise it is possible
to damage the monitor inside!

5.7 Fault Finding and Repair Tips
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
repair.
such a
to set this display option code after
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.

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 upgrade 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).
The ComPair fault finding program is able to determine the
problem of the defective television, by a combination of
automatic diagnostics and an interactive question/answer
procedure.
How to Connect
This is described in the chassis fault finding database in
ComPair.

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!
Note: If you encounter any problems, contact your local
support desk
5.3.2LVDS Tool
Introduction
This Service tool (also called “ComPair Assistant 1“) may help
you to identify, in case the TV does not show any picture,
whether the Small Signal Board (SSB) or the display of a Flat
TV is defective. Thus to determine if LVDS, RGB, and sync
signals are okay.
When operating, the tool will show a small (scaled) picture on
a VGA monitor. Due to a limited memory capacity, it is not
possible to increase the size when processing high-resolution
LVDS signals (> 1280x960). Below this resolution, or when a
DVI monitor is used, the displayed picture will be full size.
How to Connect
Connections are explained in the user manual, which is packed
with the tool. The LVDS cables included in the package cover
most chassis. For some chassis, a separate cable must be
ordered.
Note: To use the LVDS tool, you must have ComPair release
2004-1 (or later) on your PC (engine version >= 2.2.05).
For every TV type number and screen size, one must choose
the proper settings via ComPair. The ComPair file will be
updated regularly with new introduced chassis information.
How to Order
•LVDS tool (incl. two LVDS cables: 31p and 20p, covering
chassis BJx, EJx, FJx and LC4.1): 3122 785 90671.
2. Pins “27” and “28” must be grounded or not connected.

Service Modes, Error Codes, and Fault Finding
5.4Error Codes
5.4.1Introduction
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.
5.4.3Error 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.
Note: If you exit SAM by disconnecting the mains from the
television set, the error buffer is not reset.
Service Modes, Error Codes, and Fault Finding
EN 23LC7.2E LA5.
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.
5.5.2Displaying the Entire Error Buffer
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.
5.6Software Upgrading
In this chassis, three SW “stacks” are used:
•TV mains SW (processor and processor NVM).
•Digital TV SW (IBO Zapper).
•1080p Panel SW (if present, depends on execution).
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.
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.
G_16221_005.eps
241006
Figure 5-14 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”.

Example: The programming is completed when the progress
bar reaches the 100% mark.
5.6.31080p Panel SW Upgrade
To upgrade the SW on the 1080p panel:
1. Remove the back cover of the TV.
2. Connect the ComPair UART cable to the UART connector
on the 1080p panel (refer to next figure).
3. Follow the instructions in ComPair.

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:

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.
5.7.1NVM 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 5-4 NVM editor overview
HexDecDescription
.ADR0x000A10Existing value
.VAL0x00000New value
.StoreStore?
5.7.2Load 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.

SRP (Service Reference Protocol) is a software tool that creates a list with all references to signal lines. The list contains
references to the signals within all schematics of a PWB. It replaces the text references currently printed next to the signal
names in the schematics. These printed references are created manually and are therefore not guaranteed to be 100%
correct. In addition, in the current crowded schematics there is often none or very little place for these references.
Some of the PW
reference list for a schematic, or there will be printed references in the schematic.
1.2. Non-SRP Schematics
There are several different signals available in a schematic:
1.2.1.Power Supply Lines
All power supply lines are available in the supply line overview (see chapter 6). In the schematics (see chapter 7) is not
indicated where supplies are coming from or going to.
It is however indicated if a supply is incoming (created elsewhere), or outgoing (created or adapted in the current schematic).
Outgoing Incoming
1.2.2. Normal Signals
For normal signals, a schematic reference (e.g. B14b) is placed next to the signals.
B14b
1.2.3. Grounds
For normal and special grounds (e.g. GNDHOT or GND3V3 etc.), nothing is indicated.
1.3. SRP Schematics
SRP is a tool, which automatically creates a list with signal references, indicating on which schematic the signals are used.
A reference is created for all signals indicated with an SRP symbol, these symbols are:
namename
namename
name
name
Remarks:
• When there is a black dot on the "signal direction arrow" it is an SRP symbol, so there will be a reference to the signal
name in the SRP list.
• All references to normal grounds (Ground symbols without additional text) are not listed in the reference list, this to keep
it concise.
• Signals that are not used in multiple schematics, but only once or several times in the same schematic, are included
in the SRP reference list, but only with one reference.
Additional Tip:
When using the PDF service manual file, you can very easily search for signal names and follow the signal over all the
schematics. In Adobe PDF reader:
• Select the signal name you want to search for, with the "Select text" tool.
• Copy and paste the signal name in the "Search PDF" tool.
• Search for all occurrences of the signal name.
• Now you can quickly jump between the different occurrences and follow the signal over all schematics. It is advised to
"zoom in" to e.g. 150% to see clearly, which text is selected. Then you can zoom out, to get an overview of the complete
schematic.
PS. It is recommended to use at least Adobe PDF (reader) version 6.x, due to better search possibilities in this version.

•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.
8.2Hardware 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.
Purpose: To keep the tuner output signal constant as the input
signal amplitude varies.
The LC7.xx chassis comes with two tuner types: the UV1318S
for the analogue sets (LC7.1x) and the TD1316AF for the
hybrid sets (LC7.2x).
For the digital tuner TD1316AF, no alignment is necessary, as
the AGC alignment is done automatically (standard value:
“15”), even during analogue reception.
The analogue tuner UV1318S can also use the default value of
“15”, however in case of problems use the following method
(use multimeter and RF generator):
•Apply a vision IF carrier of 38.9 MHz (105 dBuV = 178
mVrms) to test point F111 (input via 50 ohm coaxial cable
terminated with an RC network of series 10nF with 120
ohm to ground).
•Measure voltage on pin 1 of the tuner.
•Adjust AGC (via SAM menu: TUNER -> AGC), until voltage
on pin 1 is 3.3 +0.5/-1.0 V.
•Store settings and exit SAM.
8.3.2RGB Alignment
Before alignment, choose “TV MENU” -> “Picture” and set:
•“Brightness” to “50”.
•“Colour” to “50”.
•“Contrast” to “100”.
White Tone Alignment:
•Activate SAM.
•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.
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.
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.
EN 80LC7.2E LA8.
Alignments
•When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.
(*) This data was not available at the time of writing, but for
default settings use the column on the right.
Black Level Offset Alignment
•Activate SAM.
•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).
8.4.2How 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.

9.1Introduction
The LC7.x (development name “LC07”) is a new global chassis
for the year 2007 (LC7.1 is the analogue range, LC7.2 is the
digital range). It is the successor of the LC4.x chassis, and
covers a screen size of 26 to 47 inch for LCD and 42 to 50 inch
for Plasma sets with a new styling called “ME7”. Some key
components are:
•Audio: Sound processing is performed by a multi-standard
sound processor MSP4450 (item 7411)
•Video: Video processing is performed by the Trident video
processor SVP CV32-LF (item 7202).
For analogue reception, a standard IF demodulator is used,
whereas digital input signals (DVB-T) are processed through a
COFDM channel decoder together with an MPEG decoder
(integrated on the SSB). A so-called “Reneas” microprocessor
performs the control functionality.
Important features of this chassis are:
•AmbiLight: LED AmbiLight (where applicable) is
introduced as the successor of glass-tube AmbiLight
•1080p Full HD (where applicable).

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:
•26 and 32” sets use a “Delta” PSU
•37 and 42” sets use a “PPS” (Philips Power Solutions) PSU
•47” 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 9-2 SSB bottom view
All Power Supply Units deliver the following voltages to the
chassis:
•+24 V to the inverters
•+12 V to SSB
•+12 V and -12 V to Audio Supply
•12 V to Bolt-on Supply (where applicable)
•+5.2 V Standby voltage.

9.3DC/DC converters
A switch generates the +5.2 V (+5V_SW) from the +5.2 V
(+5V_STANDBY) supply voltage. For LCD sets, this switch is
mounted on-board the SSB. For PDP sets, this switch is
mounted on the Power Supply Panel. This results in the
+5V_STANDBY (and +5V_SW for PDP sets) voltage(s),
coming from the Power Supply Unit, is (are) used as input for
the on-board DC/DC converters.
They deliver the following voltages to the board:
•+3.3 V (+3V3_STBY)
•+5.2 V (+5V_SW) (only for LCD sets)
•+1.8 V (+1V8S_SW)
•+34 V (+VTUN)
•+3.3 V (+3V3_SW)
•+3.3 V (+3V3_MOJO)
•+1.2 V (+1V2_MOJO)

While receiving analogue signals, the signal coming from the
tuner is fed to the IF demodulator (through the SAW filters) and
then passed to the Trident Video Processor.
While receiving digital signals, the signal coming from the tuner
is fed to the channel decoder, to the MPEG decoder and then
to the Trident Video Processor.
9.4.1Video IF Amplifier
The IF-filter is integrated in a SAW (Surface Acoustic Wave)
filter. One for filtering IF-video (item 1102) and one for IF-audio
(item 1103). The type of these filters depends on the standard
to be received (region-dependency). Some filters can be
switched to another standard, what makes them suitable for
applications in multi-standard platforms. An overview of the
SAW filter diversity can be found in table “SAW filter diversity”.

9.5DVB-T Signal Processing
The DVB-T cell on the SSB is built around the “MOJO” MPEG
decoder PNX8314HS (item 7G00) and receives the signal from
the COFDM Channel Decoder TDA10046 (item 7F01). The
(hybrid) tuner TD1316AF (item 1101) supports digital (DVB-T)
reception and transports the signal via the VIM_IBO and
VIP_IBO lines. The digital data stream exits the DVB-T cell
when it is fed to the Trident SVP CX32 Video Processor (item
7202). A Common Interface (CI) slot allows reception of
encoded signals when used with a Conditional Access Module
(CAM) in combination with a smart card. See figure “Block
diagram DVB-T reception” for details.

9.4.2Automatic Gain Control
During analogue reception, the hybrid tuner receives an
external AGC voltage, coming from the demodulator to perform
automatic gain control. During digital reception, no external
AGC voltage is used but the tuners internal AGC loop is used.
Figure 9-6 Block diagram DVB-T reception
9.5.1Common Interface (CI)
Introduction
The digital sets of this chassis are provided with a special slot
called Common Interface (CI). Together with a Conditional
Access Module (CAM) and a smart card, it is possible to
receive scrambled TV programs. This means that it is not
necessary to have a separate Set Top Box to receive digital
cable SDTV and HDTV programs (however this still is
possible).
The removable smart card, distributed by cable companies,
allows you to tune digital and high definition scrambled or
encrypted cable channels through the cable antenna. The
smart card is also required to receive premium digital TV
channels and services (where available) through the cable. A
smart card functionality includes conditional access and copy
protection.
Implementation
1. The receiver receives the digital data stream.
2. The data flows into the Conditional Access Module, which
contains the content provider's unscrambling algorithms.
3. This module verifies the existence of a smart card that
contains the subscriber's authorization code.
4. If the authorization code is accepted, the CAM
unscrambles the data and returns the data to the receiver
(if the code is not accepted, the data remains scrambled,
restricting access).
5. The receiver then decodes the data and outputs it for
viewing.

The internal voltages that are used are:
•5 V (+5V_SW)
•3.3 V (+3V3_MOJO)
•1.2 V (+1V2_MOJO)
•1.8 V (+1V8S_SW).
During start-up, it is important that the +1V8S_SW line comes
up earlier than the +3V3_MOJO line. In order to implement this,
a delay circuit is added which is shown in figure “Delay
circuitry”.

Item 7J05 switches the MOSFET “on” and “off” (item 7J04).
The diode (item 6J03) performs a short-circuit protection for the
+3V3 output stage.
9.6Video Processing
The video processing is completely handled by the Trident SVP
CX32 video processor which features:
•CVBS-input for analogue signals.
•RGB-input for digital (DVB-T) signals.
•Motion and “edge-adaptive” de-interlacing.

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 input.
Through the SCART1 & 2 connectors, a monitor output is
foreseen.

9.81080p Panel (if present)
In the LC7.x chassis with 1080p full-HD LCD panel (e.g. the
42PFL7662D), an extra module called “1080p panel” is
needed, because the main video processor supports only
“single LVDS”, while the full HD LCD panel requires “dual
LVDS”.
On this panel, a “Genesis” scaler IC performs the processing.
The input is a “single LVDS” signal from the Trident video
processor, while the output is a “dual LVDS” signal for the HD
display.
Communication is done via I2C, and controlled by the Reneas
microprocessor on the SSB.
PSU
TRIDENT

Some features of the board are:
•Single LBVDS input, dual LVDS output.
•LVDS output enable/disable.
•Hue, saturation, and flesh tone adjustment (= skin tone).
•Brightness and contrast adjustment.
•Motion adaptive de-interlacer (in 1080i).
•Supported SD formats:
– HDMI and YPbPr: 480i&p, 576i&p (50 and 60 Hz).
•Supported HD 720p formats:
– HDMI and YPbPr: 720p (50 and 60 Hz).
•Supported HD 1080i formats:
– HDMI: 1080i (50 and 60 Hz).
– YPbPr: 1080i (50, 59.94, and 60 Hz).
•Supported HD 1080p formats:
– HDMI and YPbPr: 1080p (25 and 30 Hz).
The audio decoding is done entirely via the Multistandard
Sound Processor (MSP) 4450P (item 7411).
This processor covers the processing of both analogue and
(NICAM) digital input signals by processing the (analogue) IF
signal-in to processed (analogue) AF-out (baseband audio). An
internal 40 ms (stereo) audio delay line (LIP SYNC) is foreseen
and therefore no external delay line is necessary.
All internal clock signals are derived from an external
18.432 MHz oscillator, which, in NICAM or I
turn is locked to the corresponding source.
The following functionality is included:
•Automatic Standard Detection (ASD) automatically detects
the actual broadcasted TV standard
•Automatic Sound Select (ASS) automatically switches
(without any I

bilingual mode when the broadcast mode changes.

•Three I
S-inputs for signals (“DATA”, “CLK” and “WS”)
coming from the MOJO in case of digital reception
•Five analogue inputs: for EXT1 to EXT4 and HDMI
•Loudspeaker output path
•Headphone output path
•SCART-1 output path (RF)
•SCART-2 output path (WYSIWYG = monitor).
Digital audio signals coming from HDMI sources are fed to a
digital-to-analogue converter and then fed to the MSP.
In case of reception of digital TV signals, digital audio signals
coming from the MOJO are directly fed to the MSP via the
I2S_DA_IN1, I2S_WS1 and I2S_CL1 lines. This ensures a
“true digital path”.

9.9.2Audio Amplifier
The audio amplifier is an integrated class-D amplifier
(TDA8932T, item 7A01). It combines a good performance with
a high efficiency, resulting in a big reduction in heat generation.

Figure 9-12 Principle Class-D Amplifier
The Class D amplifier works by varying the duty cycle of a
Pulse Width Modulated (PWM) signal.
By comparing the input voltage to a triangle wave, the amplifier
increases duty cycle to increase output voltage, and decreases
duty cycle to decrease output voltage.
The output transistors of a Class D amplifier switch from 'full off'
to 'full on' (saturated) and then back again, spending very little
time in the linear region in between. Therefore, very little power
is lost to heat. If the transistors have a low 'on' resistance
(RDS(ON)), little voltage is dropped across them, further
reducing losses.
A Low Pass Filter at the output passes only the average of the
output wave, which is an amplified version of the input signal.
In order to keep the distortion low, negative feedback is
applied.
The advantage of Class D is increased efficiency (= less heat
dissipation). Class D amplifiers can drive the same output
power as a Class AB amplifier using less supply current.
The disadvantage is the large output filter. The main reason
for this filter is that the switching waveform results in maximum
current flow. This causes more loss in the load, which causes
lower efficiency. An LC filter with a cut-off frequency less than
the Class D switching frequency, allows the switching current
to flow through the filter instead of the load, thus reducing the
overall loss and increasing the efficiency.
9.10 HDMI
9.10.1 Introduction
Note: Text below is an excerpt from the ”HDMI Specification”
that is issued by the HDMI founders (see http://www.hdmi.org).
The High-Definition Multimedia Interface is developed for
transmitting digital signals from audiovisual sources to
television sets, projectors and other video displays.
HDMI can carry high quality multi-channel audio data and can
carry all standard and high-definition consumer electronics
video formats. Content protection technology is available.
HDMI can also carry control and status information in both
directions.
HDMI is backward compatible with DVI (1.0). Compared with
DVI, HDMI offers extra:
•YUV 4:4:4 (3 x 8-bit) or 4:2:2 (up to 2 x 12-bit), where DVI
offers only RGB 4:4:4 (3 x 8 bit).
•Digital audio in CD quality (16-bit, 32/44.1/48 kHz), higher
quality available (8 channels, 192 kHz).
•Remote control via CEC bus (Consumer Electronics
Control): allows user to control all HDMI devices with the
TV's remote control and menus.
•Smaller connector (SCART successor).
•Less cables: e.g. from 10 audio/9 video cables to 3 HDMI
cables.
9.10.2 Implementation
The IC used is the Sil 9025 (Silicon Image) third generation
HDMI receiver (item 7817 on the SSB) with following features:
•Dual HDMI input connector.
•Two EEPROMS to support EDID.
•HDMI audio.

S output to DACs which operating freq. of 32 to 192 kHz.
•I
•Integrated HDCP decryption engine.
•Built-in pre-programmed HDCP keys for copy protection.
•Colour space conversion RGB to YCbCr.
•“Hot Plug Reset” signal.
DC-protection
A DC-detection circuit is foreseen to protect the speakers. It is
built around three transistors (items 7A05 to 7A07) and
generates a protection signal (DC_PROT) to the
microprocessor in case of a DC failure in the Class D
amplifiers.

of the HDMI receiver. The ports cannot be activated at the
same moment. Switching is controlled by software.
“Hot Plug Reset” and “DDC Reset” are controlled by the
microprocessor.
The HDMI receiver will convert all RGB or YCbCr 4:2:2 signals
to 24-bit YCbCr 4:4:4. When it receives a YCbCr 4:4:4 signal it
will just pass the signal directly to the Trident Video Processor.
