Power consumption (values are indicative) - Normal operation (W)
: 250 (42) : 360 (50) - Stand-by (W) : 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.
2.3.2
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 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
(= x10-6), nano-farads (n= x10-9), or pico-farads (p= x10-12).
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 in the
Spare Parts List. Therefore, always check this list when there is
any doubt.

BGA (Ball Grid Array) ICs Introduction For more information on
how to handle BGA devices, visit this URL:
www.atyourservice.ce.philips.com (needs subscription, not available
for all regions). After login, select Magazine, then go to 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, 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.
2.2
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.
2.3.4
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 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 400C. 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 360C - 380C is reached and stabilized at the solder joint.
Heating time of the solder-joint should not exceed ~ 4 sec. Avoid
temperatures above 400C, 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
2.32.3.1
NotesGeneral Measure the voltages and waveforms with regard to
the chassis (= tuner) ground (H), or hot ground (I), depending on
the tested area of circuitry. The voltages and waveforms shown in
the diagrams are indicative. Measure them in the Service Default
Mode (see chapter 5) with a colour bar signal and stereo sound (L:
3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at
475.25 MHz for PAL, or 61.25 MHz for NTSC (channel 3).

Directions for Use2.3.6 Exchanging a Defective PDP If a PDP has
defective or "dead" pixels, do the following: 1. Locate the
defective pixels. 2. Indicate their positions by means of a marker
(with erasable ink!). 3. Indicate the positions of the defective
pixels in the Defects Description Form (DDF), which is published in
the PDP manuals. 4. After this, remove the PDP and return it to
your Service organisation. If a PDP has to be removed from the TV
set, always keep in mind that the PDP parts can easily be damaged
by ESD, so take the following protective measures: Do not damage
the flex foils (they are located on the left, right, upper and
lower sides of the PDP). Do not scratch the glass plate. Avoid
fingerprints. 2.3.7 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! 2.3.8 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.
avoid mixed regimes. If this cannot be avoided, carefully clear
the solder-joint from old tin and re-solder with new tin. 2.3.5
Alternative BOM identification 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.MODEL : 32PF9968/10MADE

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 Software Upgrading
5.7 Fault Finding and Repair Tips 5.2.1 General 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 (Dec) in table
Option codes OP1 ...OP7 (for all LC7.2E models) in chapter 8
Alignments, 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.
5.1
Test PointsIn 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.
5.2
Service ModesThe 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).

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, colour, 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 (STATUS 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 OSD/i+ 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 STANDBY by pressing the
mains button on the remote control transmitter or on the television
set. 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.
How to Activate To activate SDM, use one of the following
methods: Press the following key sequence on the remote control
transmitter: 062596 directly followed by the MENU button (do not
allow the display to time out between entries while keying the
sequence). Short one of the Service jumpers on the TV board during
cold start (see Figures Service jumper). Then press the mains
button (remove the short after start-up). Caution: Activating SDM
by shorting Service jumpers will override the DC speaker protection
(error 1), the General I2C error (error 4), and the Trident video
processor error (error 5). When doing this, the service-technician
must know exactly what he is doing, as it could damage the
television set.

Service ToolsComPair 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.TO TVTO I2C SERVICE CONNECTOR TO UART

LVDS 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.

Service Modes, Error Codes, and Fault FindingTable 5-3 Error
code overviewError code1) 0 1 2 3 4 5
Error CodesIntroduction 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 menus. 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 (TVs NVM) except when the NVM itself is defective.
Description No error. DC Protection of speakers. +12V protection

Item nr. Remarks
12V missing or "low". note 2 7202 When Trident IC is defective,
error 10 and 14 might also be reported. Trident communicates via
parallel bus, not via the I2C bus. The I2C bus of Trident is only
used in ComPair mode. The TV will not start-up due to critical data
not available from the NVM, but the LED will blink the error
code.

How 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.
19
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. 5.4.4 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: 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.
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).

The Blinking LED ProcedureIntroduction 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.

Software UpgradingIn this chassis, two SW stacks are used: TV
mains SW (processor and processor NVM). Digital TV SW (IBO
Zapper).
5.6.1
TV 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.
5.5.2
Displaying 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.

procedure, dont 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.

Figure 5-13 Programming complete 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 5.7 Fault Finding
and Repair TipsNotes: 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 5-4 NVM editor overviewHex .ADR
.VAL .Store 0x000A 0x0000 Store? Dec 10 0 Description Existing
value New value
LC7.2E PA
5.
EN 21
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. 5.7.3 Start-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.
On the next pages you will find start-up and shut-down flowcharts,
which might be helpful during fault finding. Please note that some
events are only related to LCD sets, and therefore not applicable
to this PDP chassis.
5.7.2
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 "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.
