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.
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
2.3.1 General
•Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the tested area of circuitry. The voltages and waveforms
shown in the diagrams are indicative. Measure them in the
Service Default Mode (see chapter 5) with a colour bar
signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated
otherwise) and picture carrier at 475.25 MHz for PAL, or
61.25 MHz for NTSC (channel 3).
•Where necessary, measure the waveforms and voltages
with (D) and without (E) aerial signal. Measure the
voltages in the power supply section both in normal
operation (G) and in stand-by (F). These values are
indicated by means of the appropriate symbols.
•The semiconductors indicated in the circuit diagram and in
the parts lists, are interchangeable per position with the
semiconductors in the unit, irrespective of the type
indication on these semiconductors.
•Manufactured under license from Dolby Laboratories.
“Dolby”, “Pro Logic” and the “double-D symbol”, are
trademarks of Dolby Laboratories.
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 (P x10
nano-farads (n= x10-9), or pico-farads (p= 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.
2.3.3 Rework on BGA (Ball Grid Array) ICs
General
Although (LF)BGA assembly yields are very high, there may
still be a requirement for component rework. By rework, we
mean the process of removing the component from the PWB
and replacing it with a new component. If an (LF)BGA is
removed from a PWB, the solder balls of the component are
deformed drastically so the removed (LF)BGA has to be
discarded.
Device Removal
As is the case with any component that, is being removed, it is
essential when removing an (LF)BGA, that the board, tracks,
solder lands, or surrounding components are not damaged. To
remove an (LF)BGA, the board must be uniformly heated to a
temperature close to the reflow soldering temperature. A
uniform temperature reduces the risk of warping the PWB.
To do this, we recommend that the board is heated until it is
certain that all the joints are molten. Then carefully pull the
component off the board with a vacuum nozzle. For the
appropriate temperature profiles, see the IC data sheet.
Area Preparation
When the component has been removed, the vacant IC area
must be cleaned before replacing the (LF)BGA.
Removing an IC often leaves varying amounts of solder on the
mounting lands. This excessive solder can be removed with
either a solder sucker or solder wick. The remaining flux can be
removed with a brush and cleaning agent.
After the board is properly cleaned and inspected, apply flux on
the solder lands and on the connection balls of the (LF)BGA.
Note: Do not apply solder paste, as this has been shown to
result in problems during re-soldering.

Safety Instructions, Warnings, and Notes
Device Replacement
The last step in the repair process is to solder the new
component on the board. Ideally, the (LF)BGA should be
aligned under a microscope or magnifying glass. If this is not
possible, try to align the (LF)BGA with any board markers.
So as not to damage neighbouring components, it may be
necessary to reduce some temperatures and times.

2.3.4 Lead-free Solder
Philips CE is producing lead-free sets (PBF) from 1.1.2005
onwards.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 5 and 6 refer to the production year, digits
7 and 8 refer to production week (in example below it is 1991
week 18).

avoid mixed regimes. If this cannot be avoided, carefully
clear the solder-joint from old tin and re-solder with new tin.
•Use only original spare-parts listed in the Service-Manuals.
Not listed standard material (commodities) has to be
purchased at external companies.
•Special information for lead-free BGA ICs: these ICs will be
delivered in so-called "dry-packaging" to protect the IC
against moisture. This packaging may only be opened
shortly before it is used (soldered). Otherwise the body of
the IC gets "wet" inside and during the heating time the
structure of the IC will be destroyed due to high (steam-)
pressure inside the body. If the packaging was opened
before usage, the IC has to be heated up for some hours
(around 90°C) for drying (think of ESD-protection!).
Do not re-use BGAs at all!
•For sets produced before 1.1.2005, containing leaded
soldering tin and components, all needed spare parts will
be available till the end of the service period. For the repair
of such sets nothing changes.
In case of doubt whether the board is lead-free or not (or with
mixed technologies), you can use the following method:
•Always use the highest temperature to solder, when using
SAC305 (see also instructions below).
•De-solder thoroughly (clean solder joints to avoid mix of
two alloys).
Caution:
profile, which is coupled to the 12NC. For an overview of these
profiles, visit the website
(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.
For BGA-ICs, you must use the correct temperature-
www.atyourservice.ce.philips.com
Figure 2-1 Serial number example
Regardless of the special lead-free logo (which is not always
indicated), one must treat all sets from this date onwards
according to the rules as described below.
Figure 2-2 Lead-free logo
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
•Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106. If lead-free solder paste is required,
please contact the manufacturer of your soldering
equipment. In general, use of solder paste within
workshops should be avoided because paste is not easy to
store and to handle.
•Use only adequate solder tools applicable for lead-free
soldering tin. The solder tool must be able:
– To reach a solder-tip temperature of at least 400°C.
– To stabilise the adjusted temperature at the solder-tip.
– To exchange solder-tips for different applications.
•Adjust your solder tool so that a temperature of around
360°C - 380°C is reached and stabilised at the solder joint.
Heating time of the solder-joint should not exceed ~ 4 sec.
Avoid temperatures above 400°C, otherwise wear-out of
tips will increase drastically and flux-fluid will be destroyed.
To avoid wear-out of tips, switch “off” unused equipment or
reduce heat.
•Mix of lead-free soldering tin/parts with leaded soldering
tin/parts is possible but PHILIPS recommends strongly to
2.3.5 Alternative BOM identification
In September 2003, Philips CE introduced a change in the way
the serial number (or production number, see Figure 2-1) is
composed. From this date on, the third digit in the serial
number (example: AG2B0335000001) indicates the number of
the alternative BOM (Bill of Materials used for producing the
specific model of TV set). 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 O.E.M.s.
By looking at the third digit of the serial number, the service
technician can see if there is more than one type of B.O.M.
used in the production of the TV set he is working with. He can
then consult the At Your Service Web site, where he can type
in the Commercial Type Version Number of the TV set (e.g.
28PW9515/12), after which a screen will appear that gives
information about the number of alternative B.O.M.s used.
If the third digit of the serial number contains the number 1
(example: AG1B033500001), then there is only one B.O.M.
version of the TV set on the market. If the third digit is a 2
(example: AG2B0335000001), then there are two different
B.O.M.s.
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.
2.3.6 Practical Service Precautions
•It makes sense to avoid exposure to electrical shock.
•Always respect voltages. While some may not be

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.
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.
3.Directions for Use
You can download this information from the following websites:
•Figures below can deviate slightly from the actual situation,
due to the different set executions.
•Follow the disassemble instructions in described order.
They apply to the 37” sets, unless stated otherwise.

.2Service Positions
For easy servicing of this set, there are a few possibilities
created:
•The buffers from the packaging.
•Foam bars (created for service).
•Aluminium service stands (created for Service).
4.2.1 Foam Bars
Figure 4-4 Foam bars
The foam bars (order code 3122 785 90580 for two pieces) can
be used for all types and sizes of Flat TVs. 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.
4.2.2 Aluminium Stands
Figure 4-5 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!

5.1Test Points
The chassis is equipped with test points (Fxxx) printed on the
circuit board assemblies. 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
Service Default mode (SDM) and Service Alignment Mode
(SAM) offers several features for the service technician, while
the Customer Service Mode (CSM) is used for communication
between the call centre and the customer. Also a service mode
for servicing the AmbiLight units is foreseen.
This chassis also offers the option of using ComPair, a
hardware interface between a computer and the TV chassis. It
offers the abilities of structured troubleshooting, error code
reading, and software version read-out for all chassis.
Minimum requirements for ComPair: a Pentium processor, a
Windows OS, and a CD-ROM drive (see also paragraph
"ComPair").
5.2.1 Service Default Mode (SDM)
Purpose
•To create a pre-defined setting, to get the same
measurement results as given in this manual.
•To override SW protections detected by stand-by
processor and make the TV start up to the step just before
protection (a sort of automatic stepwise start up). See
paragraph “Stepwise Start Up”.
•To override SW protections detected by Viper (PNX8550).
Depending on the SW version it is possible that this
mechanism does not work correctly. See also paragraph
“Error codes”.
•To start the blinking LED procedure (not valid in protection
mode).

How to Activate SDM
For DVBT TV’s there are two kinds of SDM: an analogue SDM
and a digital SDM. Tuning will happen according table “SDM
Default Settings”.
•Analogue SDM: use the standard RC-transmitter and key
in the code “062596”, directly followed by the “MENU”
button.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it "off", push the “MENU”
button again.
•Digital SDM: use the standard RC-transmitter and key in
the code “062593”, directly followed by the “MENU” button.
Depending on the software version it is possible that the
tuning will not work correctly.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it "off", push the “MENU”
button again.
•Analogue SDM can also be activated by shorting for a
moment the two solder pads [1] on the SSB, with the
indication “SDM”. They are located outside the shielding.
Activation can be performed in all modes, except when the
set has a problem with the Stand-by Processor. See figure
“Service mode pads”.
fter activating this mode, “SDM” will appear in the upper right
A
corner of the screen (if you have picture).
How to Navigate
When you press the “MENU” button on the RC transmitter, the
set will toggle between the SDM and the normal user menu
(with the SDM mode still active in the background).
How to Exit SDM
Use one of the following methods:
•Switch the set to STAND-BY via the RC-transmitter.
•Via a standard customer RC-transmitter: key in “00”sequence.
5.2.2 Service Alignment Mode (SAM)
Purpose
•To perform (software) alignments.
•To change option settings.
•To easily identify the used software version.
•To view operation hours.
•To display (or clear) the error code buffer.
How to Activate SAM
Via a standard RC transmitter: key in the code “062596”
directly followed by the “INFO” button. After activating SAM
with this method a service warning will appear on the screen,
you can continue by pressing the red button on the RC.
Contents of SAM:
•Hardware Info.
– A. SW Version. Displays the software version of the
VIPER software (main software) (example: BX31E-
1.2.3.4_12345 = AAAAB_X.Y.W.Z_NNNNN).
•AAAA= the software name.
•B= the region: A= AP, E= EU, L= LatAm, U = US.
For AP sets it is possible that the Europe software
version is used.
•X.Y.W.Z= the software version, where X is the
main version number (different numbers are not
compatible with one another) and Y.W.Z is the sub
version number (a higher number is always
compatible with a lower number).
•NNNNN= last five digits of 12nc code of the
software.
– B. SBY PROC Version. Displays the software version
of the stand-by processor.
– C. Production Code. Displays the production code of
the TV, this is the serial number as printed on the back
of the TV set. Note that if an NVM is replaced or is
initialized after corruption, this production code has to
Service Modes, Error Codes, and Fault Finding
be re-written to NVM. ComPair will foresee in a
possibility to do this.
•Operation Hours. Displays the accumulated total of
operation hours (not the stand-by hours). Every time the
TV is switched "on/off", 0.5 hours is added to this number.
•Errors. (Followed by maximal 10 errors). The most recent
error is displayed at the upper left (for an error explanation
see paragraph “Error Codes”).
•Defective Module. Here the module that generates the
error is displayed. If there are multiple errors in the buffer,
which are not all generated by a single module, there is
probably another defect. It will then display the message
“UNKNOWN” here. Not all errors will display a defective
module name.
•Reset Error Buffer. When you press “cursor right” and
then the “OK” button, the error buffer is reset.
•Alignments. This will activate the “ALIGNMENTS” submenu.
•Dealer Options. Extra features for the dealers.
•Options. Extra features for Service. For more info
regarding option codes, see chapter 8.
Note that if you change the option code numbers, you have
to confirm your changes with the “OK” button before you
store the options. Otherwise you will lose your changes.
•
Initialise NVM. When an NVM was corrupted (or replaced)
in the former EMG based chassis, the microprocessor
replaces the content with default data (to assure that the
set can operate). However, all preferences and alignment
values are gone now, and option numbers are not correct.
Therefore, this was a very drastic way. In this chassis, the
procedure is implemented in another way: The moment the
processor recognizes a corrupted NVM, the “initialize
NVM” line will be highlighted. Now, you can do two things
(dependent of the service instructions at that moment):
– Save the content of the NVM via ComPair for
development analysis, before initializing. This will give
the Service department an extra possibility for
diagnosis (e.g. when Development asks for this).
– Initialize the NVM (same as in the past, however now it
happens conscious).
Note: When you have a corrupted NVM, or you have replaced
the NVM, there is a high possibility that you will not have picture
any more because your display option is not correct. So, before
you can initialize your NVM via the SAM, you need to have
picture and therefore you need the correct display option. To
adapt this option, you can use ComPair (the correct HEX
values for the options can be found in the table below) or a
method via a standard RC (described below).
Changing the display option via a standard RC:
Key in the code “062598” directly followed by the “MENU”
button and “XXX” (where XXX is the 3 digit decimal display
option code as mentioned in the first column of the next table).
Make sure to key in all three digits, also the leading zero’s.
If the above action is successful, the front LED will go out as an
indication that the RC sequence was correct.
After the display option is changed in the NVM, the TV will go
to the Stand-by mode.
If the NVM was corrupted or empty before this action, it will be
initialised first (loaded with default values). This initialising can
take up to 20 seconds.
•Store. All options and alignments are stored when
pressing “cursor right” and then the “OK”-button
•SW Maintenance.
– SW Events. Not useful for Service purposes. In case
of specific software problems, the development
department can ask for this info.
– HW Events. Not useful for Service purposes. In case
of specific software problems, the development
department can ask for this info.
•Operation hours PDP. Here you are able to reset the
operations hours of the plasma display. This has to be
done in case of replacement of the display.
•Upload to USB. Here you are able to upload several
settings from the TV to a USB stick which is connected to
the Side IO. The four items are “Channel list”, “Personal
settings”, “Option codes” and “Display-related alignments”.
First you have to create a directory “repair\” in the root of
the USB stick.To upload the settings you have to select
each item separately, press “cursor right”, confirm with
“OK” and wait until “Done” appears. Now the settings are
stored onto your USB stick and can be used to download
onto another TV or other SSB. Uploading is of course only
possible if the software is running and if you have picture.
This method is created to be able to save the customer’s
TV settings and to store them into another SSB.
•Download from USB. Here you are able to download
several settings from the USB stick to the TV. Same way of
working as with uploading. To make sure that the download
of the channel list from USB to the TV is executed properly,
it is necessary to restart the TV and tune to a valid preset if
necessary.
How to Navigate
•In SAM, you can select the menu items with the “CURSOR
UP/DOWN” key on the RC-transmitter. The selected item
will be highlighted. When not all menu items fit on the
screen, move the “CURSOR UP/DOWN” key to display the
next/previous menu items.
•With the “CURSOR LEFT/RIGHT” keys, it is possible to:
– (De) activate the selected menu item.
– (De) activate the selected sub menu.
•With the “OK” key, it is possible to activate the selected
action.
How to Exit SAM
Use one of the following methods:
•Press the “MENU” button on the RC-transmitter.
•Switch the set to STAND-BY via the RC-transmitter.
5.2.3 Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer or the Customer Helpdesk. The service
technician can then ask the customer to activate the CSM, in
order to identify the status of the set. Now, the service
technician can judge the severity of the complaint. In many
cases, he can advise the customer how to solve the problem,
or he can decide if it is necessary to visit the customer.
The CSM is a read only mode; therefore, modifications in this
mode are not possible.
When in this chassis, CSM is activated, a colour bar test
pattern will be visible for 5 seconds. This test pattern is
generated by the Pacific3. So if you see this test pattern you
can determine that the back end video chain (Pacific3, LVDS
and display) is working.
Also new in this chassis: when you activate CSM and there is
a USB stick connected to the TV, the software will dump the
complete CSM content to the USB stick. The file (Csm.txt) will
be saved in the root of your USB stick. This info can be handy
if you don’t have picture.
How to Activate CSM
Key in the code “123654” via the standard RC transmitter.
Note: Activation of the CSM is only possible if there is no (user)
menu on the screen!
How to Navigate
By means of the “CURSOR-DOWN/UP” knob on the RCtransmitter, you can navigate through the menus.
Contents of CSM
•Set Type. This information is very helpful for a helpdesk/
workshop as reference for further diagnosis. In this way, it
is not necessary for the customer to look at the rear of the
TV-set. Note that if an NVM is replaced or is initialized after
corruption, this set type has to be re-written to NVM.
ComPair will foresee a possibility to do this.
•Production Code. Displays the production code (the serial
number) of the TV. Note that if an NVM is replaced or is
initialized after corruption, this production code has to be
re-written to NVM. ComPair will foresee a possibility to do
this.
•Code 1. Gives the latest five errors of the error buffer. As
soon as the built-in diagnose software has detected an
error the buffer is adapted. The last occurred error is
displayed on the leftmost position. Each error code is
displayed as a 2-digit number. When less than 10 errors
occur, the rest of the buffer is empty (00). See also
paragraph Error Codes for a description.
•Code 2. Gives the first five errors of the error buffer. See
also paragraph Error Codes for a description.
•Options 1. Gives the option codes of option group 1 as set
in SAM (Service Alignment Mode).
•Options 2. Gives the option codes of option group 2 as set
in SAM (Service Alignment Mode).
•12NC SSB. Gives an identification of the SSB as stored in
NVM. Note that if an NVM is replaced or is initialized after
corruption, this identification number has to be re-written to
NVM. ComPair will foresee a possibility to do this.
This identification number consists of 14 characters and is
built up as follows:
- 8 last characters of the 12NC of the SSB itself.
- the serial number of the SSB, which consists of 6 digits.
Both can be found on a sticker on the PWB of the SSB itself
(not on the sticker on the outside of the shielding!). The
format of the identification number is then as follows:
<last 8 characters of 12NC of SSB><serial number of
SSB> (total 14 characters).
•Digital Natural Motion. Gives the last status of the Digital
Natural Motion setting, as set by the customer. Possible
values are “Off”, “Minimum” and “Maximum”. See DFU on

sided Ambi Light units whereas the single fitted boards are
used in sets with 2 sided Ambi Light units. A double fitted board
can drive 2 lamp units (6 lamps) and a single fitted board can
drive 1 lamp unit (3 lamps).
The double fitted boards are supplied by +12Va and +12Vb.
The microprocessor is supplied by +12Va.
Therefore, if only +12Va is available, lamp unit B will not work.
See figure “Building blocks of Converter Board” for details.
Figure 5-4 Building blocks of Converter Board
The microprocessor performs the following tasks:
•Dimming of Ambi Light by means of PWM.
•Translation of I
2
C-bus commands to PWM.
•Switches the Ambi Light board to protection if needed (in
case of protection only the lamps switch off, no set
protection is triggered).
When the TV is in a protection state due to an error detected by
standby software (and thus blinking an error) and SDM is
activated via shortcutting the pins on the SSB, the TV starts up
until it reaches the situation just before protection. So, this is a
kind of automatic stepwise start-up. In combination with the
start-up diagrams below, you can see which supplies are
present at a certain moment. Important to know here is, that if
e.g. the 3V3 detection fails (and thus error 11 is blinking) and
the TV is restarted via SDM, the Stand-by Processor will
enable the 3V3, but will not go to protection now. The TV will
stay in this situation until it is reset (Mains/AC Power supply
interrupted).
When the TV is in protection state due to an error detected by
main software (Viper protection) and SDM is activated via
shortcutting the pins on the SSB, the TV starts up and ignores
the error. Due to architectural reasons it is possible that the TV
will end up in an undefined state (e.g. when the fast I
2
C bus is
blocked). In this case diagnose has to be done via ComPair.
The abbreviations “SP” and “MP” in the figures stand for:
•SP: protection or error detected by the Stand-by
Processor.
•MP: protection or error detected by the VIPER Main
Processor.
In the next transition diagrams for “POD” should be read “CI”.
There are two ways of protection: parallel arcing protection and
serial arcing protection.
Parallel arcing protection is performed by sensing the switching
frequency. In case of short circuit of the transformer output, this
frequency > 100 kHz and the board goes into protection.
Serial arcing protection is performed by detection of arc in
ground wire of the lamp units. In this case, the protection pulse
is transmitted via an opto-coupler.
Protection can be disabled by short-circuiting diode 6112 or
capacitor 2173 or by connecting pin 8 of the microprocessor to
ground.
Repair Tips
In case only one or no lamp unit at all works, probably the
+12Vb (12 - 13 V) is not available or the fuse is broken. Check
for broken MOSFETS or check if they are switched off properly
by the transistors connected to the PWM outputs of the
microprocessor.
In case the Ambi Light switches off after two seconds, serial
arcing or parallel arcing protection is active. Serial arcing
protection can be excluded by disconnecting the opto-coupler;
check for bad solder joints on transformer or lamp units.
Parallel arcing protection can be disabled by grounding pin 8 of
the microprocessor. Usually the switching frequency (normally
63 kHz) will then be too high. Possible causes are one
MOSFET of the converter has no gate drive or is broken, or
there is a short-circuit of the output of the transformer.
5.3Stepwise Start-up
The stepwise start-up method, as known from FTL/FTP sets
(EMG based sets) is not valid any more. There are two possible
situation: one for protections detected by standby software and
one for protections detected by main software.

The availability of th e supplies is checked through detect signals (delivered b y
dedicated detect -IC's) going to the st-by µP. These signals are available fo r
+12V, +8V6, +5V, +1V2 and +2V5. A low to high transition of the signals should
occur within a cert ain time after togg ling the standby line. If a n observers is
detected befor e the time-out elapses, of course, the process should continue in

- Only when the PDPGO is low, a retry sho uld be
considered (th e PDP could have reset inte rnally). If
the PDPGO is already high, there is no use in trying
to restart.
- PDPGO line is pulled high in all non FHP sets so
this extra startu p delay in case o f a fault condition

5.4Service Tools
5.4.1 ComPair
Introduction
ComPair (Computer Aided Repair) is a service tool for Philips
Consumer Electronics products. ComPair is a further
development on the European DST (service remote control),
which allows faster and more accurate diagnostics. ComPair
has three big advantages:
1. ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you
systematically through the repair procedures.
2. ComPair allows very detailed diagnostics (on I
is therefore capable of accurately indicating problem areas.
You do not have to know anything about I2C 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
microprocessor is working) and all repair information is
directly available. When ComPair is installed together with
the Force/SearchMan electronic manual of the defective
chassis, schematics and PWBs are only a mouse click
away.
Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The ComPair interface box is connected to the PC via a serial
(or RS-232) cable.
For this chassis, the ComPair interface box and the TV
communicate via a bi-directional service cable via the service
connector(s).
The ComPair fault finding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:
•Automatically (by communicating with the television):
ComPair can automatically read out the contents of the
entire error buffer. Diagnosis is done on I
ComPair can access the I2C/UART bus of the television.
ComPair can send and receive I2C/UART commands to
the microcontroller of the television. In this way, it is
possible for ComPair to communicate (read and write) to
devices on the I
•Manually (by asking questions to you): Automatic
diagnosis is only possible if the microcontroller of the
television is working correctly and only to a certain extent.
When this is not the case, ComPair will guide you through
the fault finding tree by asking you questions
screen give a picture? Click on the correct answer: YES /
NO) and showing you examples (e.g. Measure test-point I7
and click on the correct oscillogram you see on the
oscilloscope). You can answer by clicking on a link (e.g.
text or a waveform picture) that will bring you to the next
step in the fault finding process.
By a combination of automatic diagnostics and an interactive
question / answer procedure, ComPair will enable you to find
most problems in a fast and effective way.
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 below (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.

5.4.2 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.
Furthermore it is possible to program EPLDs with this tool (Byte
blaster). Read the user manual for an explanation of this
feature.
Since 2004, the LVDS output connectors in our Flat TV models
are standardised (with some exceptions). With the two
delivered LVDS interface cables (31p and 20p) you can cover
most chassis (in special cases, an extra cable will be offered).
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.
Generally this tool is intended to determine if the SSB is
working or not. Thus to determine if LVDS, RGB, and sync
signals are okay.
How to Connect
Connections are explained in the user manual, which is packed
with the tool.

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.

The error code buffer contains all detected errors since the last
time the buffer was erased. The buffer is written from left to
right, new errors are logged at the left side, and all other errors
shift one position to the right.
When an error occurs, it is added to the list of errors, provided
the list is not full. When an error occurs and the error buffer is
full, then the new error is not added, and the error buffer stays
intact (history is maintained), except when the error is a
protection error.
To prevent that an occasional error stays in the list forever, the
error is removed from the list after more than 50 hrs. of
operation.
When multiple errors occur (errors occurred within a short time
span), there is a high probability that there is some relation
between them.
•Via the blinking LED procedure (when you have no
picture). See next paragraph.
•Via ComPair.
5.5.3 How to Clear the Error Buffer
Use one of the following methods:
•By activation of the “RESET ERROR BUFFER” command
in the SAM menu.
•With a normal RC, key in sequence “MUTE” followed by
“062599” and “OK”.
•If the content of the error buffer has not changed for 50+
hours, it resets automatically.
5.5.4 Error Buffer
In case of non-intermittent faults, clear the error buffer before
you begin the repair (before clearing the buffer, write down the
content, as this history can give you significant information).
This to ensure 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
code and not the actual cause (e.g., a fault in the protection
detection circuitry can also lead to a protection).
There are several mechanisms of error detection:
•Via error bits in the status registers of ICs.
•Via polling on I/O pins going to the stand-by processor.
•Via sensing of analogue values on the stand-by processor
or the Viper.
•Via a “not acknowledge” of an I
Take notice that some errors need more than 90 seconds
before they start blinking. So in case of problems wait 2
minutes from start-up onwards, and then check if the front LED
is blinking.
2
C communication
Basically there are three kinds of errors:
•Errors detected by the Stand-by Processor. These
errors will always lead to protection and an automatic start
of the blinking LED for the concerned error (see paragraph
“The Blinking LED Procedure”). In these cases SDM can
be used to start up (see chapter “Stepwise Start-up”). Note
that it can take up to 90 seconds before the TV goes to
protection and starts blinking the error (e.g. error 53)
•Errors detected by VIPER that lead to protection. In this
case the TV will go to protection and the front LED should
also blink the concerned error. Depending on the software
version it is possible that this mechanism does not work.
See also paragraph “Error Codes” -> “Error Buffer” ->
“Extra Info”.
•Errors detected by VIPER that do not lead to protection. In this case the error will be logged into the
error buffer and can be read out via ComPair, via blinking
LED method, or in case you have picture, via SAM.
5.5.2 How to Read the Error Buffer
Use one of the following methods:
•On screen via the SAM (only if you have a picture). E.g.:
– 00 00 00 00 00: No errors detected
– 06 00 00 00 00: Error code 6 is the last and only
detected error
– 09 06 00 00 00: Error code 6 was first detected and
error code 9 is the last detected error

Extra Info
•Rebooting. When a TV is constantly rebooting due to
internal problems, most of the time no errors will be logged
or blinked. This rebooting can be recognised via a ComPair
interface and Hyperterminal (for Hyperterminal settings,
see paragraph “Stand-by software upgrade). You will see
that the loggings which are generated by the main software
keep continuing. In this case (rebooting) diagnose has to
be done via ComPair.
•Error 1 (I
2
C bus 1 blocked). When this error occurs, the
TV will go to protection and the front LED will blink error 1.
Now you can start up the TV via the SDM short-cut pins on
the SSB. The TV will start up and ignore the error.
Depending on the problem it is even possible that you have
picture.
•Error 2 (I
2
C bus 2 blocked). Due to hardware restriction
(I2C bus 2 is the fast I2C bus) it will be impossible to start
up the VIPER when I2C bus 2 is blocked. When this error
occurs, the TV will not start up (but probably you will see
the green LED). Starting up the TV via the SDM short-cut
pins will not work. So it will not be possible to read out error
2 via internal software (allthough it will be logged). Use
ComPair for further diagnose (e.g. read out the NVM
content).
•Error 3 (I
2
C bus 3 blocked). There are only three devices
on I2C bus 3: VIPER, Stand-by Processor, and NVM. The
Stand-by Processor is the detection device of this error, so
this error will only occur if the VIPER or the NVM is blocking
the bus. This error will also blink when the NVM gives no
acknowledge on the I
2
C bus. Note that if the 12 V supply is
missing, the DC/DC supply on the SSB will not work.
Therefore the VIPER will not get supplies and could block
2
I
C bus 3. So, a missing 12 V can also lead to an error 3.
•Error 4 (I2C bus 4 blocked). When this error occurs, the
TV will go to protection and the front LED will blink error 4.
Now you can start up the TV via the SDM short-cut pins on
the SSB. The TV will start up and ignore the error.
Depending on the problem it is even possible that you have
picture.
•Error 5 (VIPER does not boot). This error will point to a
severe hardware problem around the VIPER (supplies not
OK, VIPER completely dead, I
2
C link between VIPER and
Stand-by Processor broken, etc...).
•Error 7 (8V6 error). In case of a TV with SDI display you
will see error 7 blink in case of an audio protection. So
except a problem with the 8V6 itself it is also possible that
there is something wrong with the audio part. See also
paragraph "Hardware Protections" for this.
•Error 14 (Audio protection). The detection is done on the
audio board itself. Several items are monitored:
overvoltage, overcurrent, DC level on the speakers and the
audio supply voltages. If one of these items fails, the
audioprotection will switch off the main supply. All supplies
will drop, the standby processor “thinks” there is a mains
dip, and will reboot. At the beginning of the boot process,
the audio-protection line is monitored: if this line is “active”,
the set will go to protection and will blink error 14.
•Error 27 (PNX2015 HD subsystem part). Diagnosing this
error will not be possibly via the normal errorcodes. In case
this device can not communicate with the Viper via I²C, it
will not be possible to initialise the tunnelbus. Hence the
software will not be able to start up, and will re-boot
constantly. Diagnosing these problems will only be
possible via ComPair. In theory it is possible that the error
is logged in the NVM (that’s why this error is still mentioned
here).
•Error 29 (AVIP 1). Same remark as for error 27.
•Error 31 (AVIP 2). Same remark as for error 27.
•Error 44 (NVM). This error will probably never occur
because it is masked by error 3 (I
2
C bus 3). The detection
mechanism for error 3 checks on an I2C acknowledge of
the NVM. If NVM gives no acknowledge, the stand-by
software assumes that the bus is blocked, the TV goes to
protection and error 3 will be blinking..
•Error 46 (Pacific 3). When this errors occurs the TV will go
to stand-by. The reason for this is, when there is an
occasional boot problem of the Pacific, it will look like the
TV has started up in stand-by mode, and the customer can
switch it on again. When there is an actual problem with or
around the Pacific the TV will go to stand-by every time you
try to start up. So this behaviour is an indication of a Pacific
problem.
Service Modes, Error Codes, and Fault Finding
EN 43BJ3.0E LA5.
•Error 53. This error will indicate that the VIPER has started
to function (by reading his boot script, if this would have
failed, error 5 would blink) but initialization was never
completed because of hardware peripheral problems
(NAND flash, ...) or software initialization problems.
Possible cause could be that there is no valid software
loaded (try to upgrade to the latest main software version).
Note that it takes 90 seconds before the TV goes to
protection in this case.
•Error 55 (SPIDER error). Same remark as for error 27.
•Error 63 (POWER OK). When this error occurs, it means
that the POWER-OK line did not became “high”. This error
is only applicable for TV’s with a SDI display, a FHP display
or a Sharp full HD display. Depending on the software
version it is possible that the detection mechanism of this
error does not function and that the TV keeps rebooting.
•Error 64 (Display error). When this error occurs it means
that there is a problem with the I
the display. Allthough several display types communicate
2
via I
C, this error will only work for TV’s with a FHP display.

5.6The Blinking LED Procedure
5.6.1 Introduction
The blinking LED procedure can be split up into two situations:
•Blinking LED procedure in case of a protection detected by
the stand-by processor. In this case the error is
automatically blinked. This will be only one error, namely
the one that is causing the protection. Therefore, you do
not have to do anything special, just read out the blinks. A
long blink indicates the decimal digit, a short blink indicates
the units.
•Blinking LED procedure in the “on” state. Via this
procedure, you can make the contents of the error buffer
visible via the front LED. This is especially useful for fault
finding, when there is no picture.
When the blinking LED procedure is activated in the “on” state,
the front LED will show (blink) the contents of the error-buffer.
Error-codes > 10 are shown as follows:
5. When all the error-codes are displayed, the sequence
finishes with a LED blink of 3 s,
6. The sequence starts again.
Example: Error 12 8 6 0 0.
After activation of the SDM, the front LED will show:
1. 1 long blink of 750 ms (which is an indication of the decimal
digit) followed by a pause of 1.5 s,
2. 2 short blinks of 250 ms followed by a pause of 3 s,
3. 8 short blinks followed by a pause of 3 s,
4. 6 short blinks followed by a pause of 3 s,
5. 1 long blink of 3 s to finish the sequence,
6. The sequence starts again.
second last error, etc.... Take notice that it takes some
seconds before the blinking LED starts.
5.7Protections
5.7.1 Software Protections
Most of the protections and errors use either the stand-by
microprocessor or the VIPER controller as detection device.
Since in these cases, checking of observers, polling of ADCs,
filtering of input values are all heavily software based, these
protections are referred to as software protections.
There are several types of software related protections, solving
a variety of fault conditions:
•Protections related to supplies: check of the 12V, +5V,
+8V6, +1.2V and +3.3V.
•Protections related to breakdown of the safety check mechanism. E.g. since a lot of protection detections are
done by means of the VIPER, failing of the VIPER
communication will have to initiate a protection mode since
safety cannot be guaranteed any more.
Remark on the Supply Errors
The detection of a supply dip or supply loss during the normal
playing of the set does not lead to a protection, but to a cold
reboot of the set. If the supply is still missing after the reboot,
the TV will go to protection.
Protections during Start-up
During TV start-up, some voltages and IC observers are
actively monitored to be able to optimise the start-up speed,
and to assure good operation of all components. If these
monitors do not respond in a defined way, this indicates a
malfunction of the system and leads to a protection. As the
observers are only used during start-up, they are described in
the start-up flow in detail (see paragraph “Stepwise Start-up").
5.7.2 Hardware Protections
There are no real hardware protections in this chassis..
Allthough, in case of an audio problem, the audio protection
circuit will switch off the main supply. The stand-by
microprocessor will interpret this as a mains dip and will try to
start up again.
In case of a TV with SDI display this will probably lead to
protection error 7 (8V6 error) and an internal error 11 (so it
looks like an overvoltage protection of the SDI supply itself).
In other cases it will lead to error 14 (audio protection).
Repair Tips
•It is also possible that you have an audio DC protection
because of an interruption in one or both speakers (the DC
voltage that is still on the circuit cannot disappear through
the speakers).
5.6.2 How to Activate
Use one of the following methods:
•Activate the SDM. The blinking front LED will show the
entire contents of the error buffer (this works in “normal
operation” mode).
•Transmit the commands “MUTE” - “062500” - “OK” with a normal RC. The complete error buffer is shown.
Take notice that it takes some seconds before the blinking
LED starts.
•Transmit the commands “MUTE” - “06250x” - “OK” with a normal RC (where “x” is a number between 1 and
5). When x= 1 the last detected error is shown, x= 2 the

Service Modes, Error Codes, and Fault Finding
5.8.1 Exit “Factory Mode”
When an "F" is displayed in the screen's right corner, this
means that the set is in "Factory" mode, and it normally
happens after a new SSB has been mounted.
To exit this mode, push the "VOLUME minus" button on the
TV's keyboard control for 5 seconds and restart the set.
When a DVBT TV starts up in factory mode, the TV will tune to
preset 0. When there is no channel installed on preset 0, there
will be no picture and it will look like the set is in standby mode.
De-activating factory mode can also be done via the above
method.
5.8.2 MPIF
Important things to make the MPIF work:
•Supply.
•Clock signal from the AVIP.
2
•I
C from the VIPER.
When there is no sound an external sources, check the audio
supply of the MPIF.
5.8.3 AVIP
Important things to make the AVIP work:
•Supplies.
•Clock signal from the VIPER.
2
•I
C from the VIPER (error 29 and 31).
5.8.4 PACIFIC 3
In case the Pacific fails, the TV will go to stand-by. The reason
for this is, when there is an occasional boot problem of the
Pacific, it will look like the TV has started up in stand-by mode,
and the customer can switch it on again. When there is an
actual problem with or around the Pacific the TV will go to
stand-by every time you try to start up. So this behaviour is an
indication of a Pacific problem.
5.8.5 Ambilight
Note: in case of Ambilight protection, the TV itself will not go to
protection, only the Ambilight board. When you disconnect the
TV from the mains and reconnect again, the Ambilights will
work again.
In case of multiple protections, check and replace the invertor
transformers and/or the lamp unit(s).
Protections on the ambilight boards:
Parallel arcing protection.In normal operation the inverter
frequency is ±63 kHz. In case of short circuit of the transformer
output the frequency is >100 kHz. Protection is done via
sensing the switching frequency.
Serial arcing protection. The detection of the arcing is done
in the ground wire of lamp units. The µProcessor is counting the
protection pulses. When 50 pulses are counted within 2
seconds protection will be triggered.
5.8.6 Sanken display supply.
All 42” LCD sets for this chassis have a Sanken display supply.
If this supply fails there will be no error or protection because
there is no feedback foreseen from the supply towards the
SSB. The result of a failing Sanken display supply could be that
there is no picture, but that you will probably have sound and 1
out of 3 ambilights will still work (in case ambilight is switched
on).
5. Check the over-current detection circuit (2U18 or 3U83 interrupted).
Another result of a failing Sanken display is of course that the
set is completely dead.
When the primary circuit of the platform supply fails, there is a
high possibility that the main fuse of the Sanken display supply
will break. In this case the Sanken supply must not be replaced
completely. That fuse can be ordered separately (order code
2422 086 00689, Bel Fuse 5x20 HT 6A3 250 V). For safety
reasons, make sure to use the correct fuse type.
5.8.7 DC/DC Converter
Introduction
•The best way to find a failure in the DC-DC converters is to
check their starting-up sequence at power-on via the mains
cord, presuming that the standby PP is operational.
•If the input voltage of DC-DC converters is around 12V
(measured on decoupling capacitors 2U17/2U25/2U45)
and the enable signals are low (active) then the output
voltages should have their normal values. First, the
standby PP activates the +1V2 supply (via ENABLE-1V2)
then, after this voltage becomes present and is detected
OK (about 100ms), the other two voltages (+2V5 and
+3V3) will be activated (via ENABLE-3V3). The Vtun
generator (present only for the analogue version of Jaguar
Baby) will generate +33V for the analogue tuner as soon as
the 12V/3.3V DC-DC converter will start operating.
•The consumption of controller IC 7U00 is around 30mA
(that means around 300mV drop voltage across resistor
3U22).
•The current capability of DC-DC converters is quite high
(short-circuit current is 7 to 10A), therefore if there is a
linear integrated stabilizer that, for example delivers 1.8V
from +3V3 with its output overloaded, the +3V3 stays
usually at its normal value even though the consumption
from +3V3 increases significantly.
•The +2V5 supply voltage is obtained via a linear stabilizer
made with discrete components that can deliver a lot of
current, therefore in case +2V5 (or +2V5D) is shortcircuited to GND then +3V3 will not have the normal value
but much less. There is a +2V5D low power linear stabilizer
(to supply the DDR memories in standby mode) that is not
used. In normal operation mode the value of this supply
voltage will be close to +2V5 (20..30 mV difference).
•The supply voltages +5V and +8V6 are available from
connector 1M46; they are not protected by fuses. +12VSW
is protected for over-currents by the fuse 1U04 while 1U01
is protecting in case of defects in DC-DC converters. There
are on-board switches for +8V6-SW (see "DC-DC
CONNECTIONS" schematic) and +12VSW but they are
not used (by-passed).
Fault Finding
•Symptom: +1V2, +2V5 and +3V3 not present (even for a
short while ~10ms)
power MOS-FETs) and enable signal ENABLE-1V2
(active low),
2. Check the voltage on pin 9 (1.5V),
3. Check for +1V2 output voltage short-circuit to GND that
can generate pulsed over-currents 7...10A through coil
5U03,
4. Check the over-current detection circuit (2U12 or 3U97
interrupted).
•Symptom: +1V2 present for about 100ms, +2V5 and +3V3
not rising
1. Check the ENABLE-3V3 signal (active LOW),
2. Check the voltage on pin 8 (1.5V),
3. Check the under-voltage detection circuit (the voltage
on collector of transistor 7U10-1 should be less than
0.8V),
4. Check for output voltages short-circuits to GND (+3V3,
+2V5 and +2V5D) that can generate pulsed overcurrents 7...10A through coil 5U00,

•Symptom: +1V2 OK, +2V5 and +3V3 present for about
100ms. Cause: SUPPLY-FAULT line stays low even
though the +3V3 and +1V2 is available - the standby PP is
detecting that and switching off all supply voltages.
1. Check the value of +2V5 and the drop voltage across
resistor 3U22 (they could be too high),
2. Check if +1V2 or +3V3 are higher than their normal
values - that can be due to defective DC feedback of
the respective dc-dc converter (ex. 3U18 or 3UA7).
•Symptom: +1V2, +2V5 and +3V3 look ok, except the
ripple voltage that is increased (audible noise can come
from the filtering coils 5U00 or 5U03).
Cause: instability of the frequency and/or duty cycle of one
or both dc-dc converters.
1. Check the resistor 3U06, decoupling capacitors, AC
feedback circuits (2U20 + 2U21 + 3U14 + 3U15 for
+1V2 or 2U19 + 2U85 + 3U12 + 3U13 for +3V3),
compensation capacitors 2U09, 2U10, 2U23 and
2U73, IC 7U00.
•Symptom: +1V2, +2V5 and +3V3 ok, no +Vtun (analogue
sets only). Cause: the “VTUN GENERATOR” circuit
(second schematic) is defective.
1. Check transistor 7U24 (has to have gate pulses of
about 10V amplitude and drain pulses of about 35V
amplitude) and surrounding components.
Note: fuse 1U01 broken means usually a pair of power MOSFETs (7U01 or 7U03) defective. The IC 7U00 should be
replaced as well in this case
5.9Software Upgrading
5.9.1 Introduction
5.9.2 Main Software Upgrade
The software image resides in the NAND-Flash, and is
formatted in the following way:
Figure 5-25 NAND-Flash format
Executables are stored as files in a file system. The boot loader
(uBTM) will load the USB Download Application in partition 0
(USB drivers, boot script, etc.). This application makes it then
possible to upgrade the main software via USB.
Installing "Partition 0" software is possible via an external
EJTAG tool, but also in a special way with the USB stick (see
description in paragraph “Partition 0“).
Partition 1 (Customer)
To do a main software upgrade (partition 1) via USB, the set
must be operational, and the "Partition 0" files for the VIPER
must be installed in the NAND-Flash!
The set software and security keys are stored in a NANDFlash, which is connected to the VIPER via the PCI bus.
It is possible for the user to upgrade the main software via the
USB port. This allows replacement of a software image in a
stand alone set, without the need of an E-JTAG debugger. A
description on how to upgrade the main software can be found
in chapter 3 "Directions For Use".
Important: When the NAND-Flash must be replaced, a new
SSB must be ordered, due to the presence of the security
keys!!! (copy protection keys, MAC address, for US the POD
keys, ...). See table “SSB service kits” for the order codes.
Perform the following actions after SSB replacement:
1. Set the correct option codes (see sticker inside the TV).
2. Update the TV software (see chapter 3 for instructions).
3. Perform the alignments as described in chapter 8.
4. Check in CSM if the HDMI keys are valid.

reference purposes. Do not use this code when ordering a new
SSB.
The new software can be uploaded to the TV by using a
portable memory device or USB storage compliant devices
(e.g. USB memory stick). You can download the new software
from the Philips website to your PC.
Partition 0 (Service)
If the "Partition 0" software is corrupted, the software needs to
be re-installed.
To upgrade this “USB download application” (partition 0 except
the boot block), insert an USB stick with the correct software,
and press the “red” button on the remote control (in ”TV” mode)
when it is asked via the on screen text.
Caution:
•The USB download application will now erase both
partitions (except the boot block), so you need to reload the
main SW after upgrading the USB download application.
As long as this is not done, the USB download application
will start when the set is switched “on”.
•When something goes wrong during the progress of this
method (e.g. voltage dip or corrupted software file), the set
will not start up, and can only be recovered via the EJTAG
tool!
5.9.3 Manual Start of the Software Upgrade Application
Normally, the software upgrading procedure will start
automatically, when a memory device with the correct software
is inserted, but in case this does not work, it is possible to force
the TV into the software upgrade application. To do so:
•Disconnect the TV from the Mains/AC Power.
•Press the “OK” button on a Philips DVD RC-6 remote
control (it is also possible to use the TV remote in "DVD"
mode).
•Keep the “OK” button pressed while connecting the TV to
the Mains/AC Power.
•The software upgrade application will start.
•When a memory device with upgrade software is
connected, the upgrade process will start.

5.9.4 Stand-by Software Upgrade
There are two methods now to upgrade stand-by software:
Upgrade via USB
In this chassis it is possible to upgrade stand-by software via a
USB stick. The method is similar to upgrading main software
via USB.
Use the following steps:
1. Create a directory “upgrades” on your USB stick.
2. Copy the stand-by software (delivered via the Service
organisation) into this directory.
3. Insert the USB stick into the TV.
4. Start the download application manually (see paragraph
“Manual start of the Software Upgrade Application”).
5. Select the appropriate file and press the red button to
upgrade:
Upgrade via PC and ComPair interface
It will be possible to upgrade the Stand-by software via a PC
and the ComPair interface. Check paragraph "ComPair" on
how to connect the interface. To upgrade the Stand-by
software, use the following steps:
1. Disconnect the TV from the Mains/AC Power.
2. Short circuit the SPI pins [2] on the SSB. They are located
outside the shielding (see figure “Service mode pads”).
3. Keep the SPI pins shorted while connecting the TV to the
Mains/AC Power.
4. Release the short circuit after approx. two seconds.
5. Start up HyperTerminal (can be found in every Windows
application via Programs -> Accessories ->
Communications -> HyperTerminal). Use the following
settings:
– COM1
– Bits per second = 38400 (9600)*
– Data bits = 8
– Parity = none
– Stop bits = 1
– Flow control = None
6. Press “Shift U” on your PC keyboard. You should now see
the following info:
– PNX2015 Loader V1.0
– 19-09-2003
– DEVID=0x05
– Erasing
– MCSUM=0x0000
– =
7. If you do not see the above info, restart the above
procedure, and check your HyperTerminal settings and the
connections between PC and TV.
8. Via “Transfer” -> “Send text file ...”, you can send the
proper upgrade file to the TV (e.g. *.hex). This file will be
distributed via the Service Organization.
9. After successful programming, you must see the following
info (this can take several minutes!):
– DCSUM=0xECB3
– :Ok
– MCSUM=0xECB3
– Programming
– PCSUM=0xECB3
– Finished
10. If you do not see this info, restart the complete procedure.
11. Close HyperTerminal.
12. Disconnect and connect Mains/AC Power again.
