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
2.1Safet y In st ructions
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
2.3.1General
•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
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 Standby (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.
2.3.2Schematic 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.
2.3.3Rework 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
EN 9FJ3.0E LA2.
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.

on how to deal with BGA-ICs.
2.3.4Lead-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).

•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: For BGA-ICs, you must use the correct temperatureprofile, 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.
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.
P
b
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 avoid mixed regimes. If this cannot be avoided, carefully
clear the solder-joint from old tin and re-solder with new tin.
2.3.5Alternative 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. Information about 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.
2.3.6Practical 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.
EN 10FJ3.0E LA3.

5.7 Protections
5.8 Fault Finding and Repair Tips
5.9 Software Upgrading
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.
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").
•All service-unfriendly modes (if present) are disabled, like:
– (Sleep) timer.
– Child/parental lock.
– Picture mute (blue mute or black mute).
– Automatic volume levelling (AVL).
– Auto switch "off" (when no video signal was received
for 10 minutes).
– Skip/blank of non-favourite pre-sets.
– Smart modes.
– Auto store of personal presets.
– Auto user menu time-out.
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 Standby Processor. See figure
“Service mode pads”.
SDM
SDM
11
5.2.1Service 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 standby 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. 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).

After activating this mode, “SDM” will appear in the upper right
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).
Service Modes, Error Codes, and Fault Finding
EN 27FJ3.0E LA5.
How to Exit SDM
Use one of the following methods:
•Switch the set to STANDBY via the RC-transmitter.
•Via a standard customer RC-transmitter: key in “00”sequence.
5.2.2Service 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: JA30E-
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 standby 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
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 standby 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
(depending 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 Standby 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.
•Operating hours. Here you are able to reset
the operations hours of the 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 STANDBY via the RC-transmitter.
5.2.3Customer 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
how to change this item.
•Pixel Plus. Gives the last status of the Pixel Plus setting,
as set by the customer. Possible values are “On” and “Off”.

(average signal) and to 255 (bad signal). For some
software versions, the noise figure will only be valid when
“Active Control” is set to “medium” or “maximum” before
activating CSM. Noise figure is not applicable for DVBT
channels.
•Headphone Volume. Gives the last status of the
headphone volume, as set by the customer. The value can
vary from 0 (volume is minimum) to 100 (volume is
maximum). See DFU on how to change this item.
•Dolby. Indicates whether the received transmitter
transmits Dolby sound (“ON”) or not (“OFF”). Attention: The
presence of Dolby can only be tested by the software on
the Dolby Signalling bit. If a Dolby transmission is received
EN 30FJ3.0E LA5.
Service Modes, Error Codes, and Fault Finding
without a Dolby Signalling bit, this indicator will show “OFF”
even though a Dolby transmission is received.
•Surround Mode. Indicates the by the customer selected
sound mode (or automatically chosen mode). Possible
values are “STEREO” and “VIRTUAL DOLBY
SURROUND”. It can also have been selected
automatically by signalling bits (internal software). See
DFU on how to change this item.

Purpose
To switch on the lamps manually in case I

fails.
The Service Mode can be activated by disconnecting
connectors 1M59 and 1M49 and then by shorting for a moment
the two solder pads [1] on the Ambi Light Inverter Panel. See
figure “Service Mode pads”.

G_15950_049.eps
Figure 5-3 Service Mode pads AmbiLight panel
In this chassis, both single and double fitted boards can be
used. The double fitted boards are used in sets with 3 or 4
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.

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.
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 Standby 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
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.

The availability of the supplies is checked through detect signals (delivered by
dedicated detect-IC's) going to the st-by µP. These signals are available for
+12V, +8V6, +5V, +1V2 and +2V5. A low to high transition of the signals should
occur within a certain time after toggling the standby line. If an observers is
detected before the time-out elapses, of course, the process should continue in
order to minimize start up time.
- Only when the PDPGO is low, a retry should be
considered (the PDP could have reset internally). If
the PDPGO is already high, there is no use in trying
to restart.
- PDPGO li ne is pulled high i n all non FHP sets so
this extra startup delay in case of a fault condition
is not valid.

5.4Service Tools
5.4.1ComPair
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 I
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 I
ComPair can send and receive I
the microcontroller of the television. In this way, it is
possible for ComPair to communicate (read and write) to
devices on the I
2
C/UART buses of the TV-set.
•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 (e.g. Does the
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.
5.4.2LVDS 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.
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.

Service Modes, Error Codes, and Fault Finding
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.
How to Order
•LVDS tool (incl. two LVDS cables: 31p and 20p):
3122 785 90671.
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.
Basically there are three kinds of errors:
•Errors detected by the Standby 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.
5.5.2How 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
•Via the blinking LED procedure (when you have no
picture). See next paragraph.
•Via ComPair.
5.5.3How 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.
5.5.4Error 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 standby processor.
•Via sensing of analogue values on the standby processor
or the Viper.
•Via a “not acknowledge” of an I
2
C communication
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.

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 “Standby 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
(I
up the VIPER when I
2
2
C bus 2 blocked). Due to hardware restriction
C bus 2 is the fast I2C bus) it will be impossible to start
2
C bus 2 is blocked. When this error
occurs, the TV will keep rebooting. 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
on I
2
C bus 3 blocked). There are only three devices
2
C bus 3: VIPER, Standby Processor, and NVM. The
Standby 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
C bus 3. So, a missing 12 V can also lead to an error 3.
I
•Error 4 (I
2
C bus 4 blocked). In this chassis, error 4 is no
longer a protection error.
•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
Standby 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 possible 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 28 (MOP/EPLD) Due to the detection mechanism of
the MOP error it is possible that the actual logging of the
error can take up to 4 minutes (worst case). So if you want
to be sure there is a MOP error, reset the error buffer,
restart the TV and wait for 4 minutes before checking the
error buffer again. The detection mechanisme for this error
has been changed to avoid false MOP errors.
•Error 44 (NVM). This error will probably never occur
because it is masked by error 3 (I
mechanism for error 3 checks on an I
2
C bus 3). The detection
2
C acknowledge of
the NVM. If NVM gives no acknowledge, the standby
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 standby. 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 standby 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 standby every time you
try to start up. So this behaviour is an indication of a Pacific
problem.
•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 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 set 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 cummunicate
2
C, this error will only work for sets with a FHP display.

Service Modes, Error Codes, and Fault Finding
5.6The Blinking LED Procedure
5.6.1Introduction
The blinking LED procedure can be split up into two situations:
•Blinking LED procedure in case of a protection detected by
the standby 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:

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.
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 set will go to protection.
Protections during Start-up
During 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").
5.7.2Hardware 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 standby
microprocessor will interpretate this as a mains dip and will try
to start up again.
In case of a set 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).
5.6.2How 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
second last error, etc.... Take notice that it takes some
seconds before the blinking LED starts.
5.7Protections
5.7.1Software Protections
Most of the protections and errors use either the
sStandbytandby 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.

5.8.1Exit “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 set starts up in factory mode, the set 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.
5.8.2MPIF
Important things to make the MPIF work:
•Supply.
•Clock signal from the AVIP.
2
C from the VIPER.
•I
When there is no sound an external sources, check the audio
supply of the MPIF.
5.8.3PACIFIC 3
In case the Pacific fails, the set will go to standby. The reason
for this is, when there is an occasional boot problem of the
Pacific, it will look like the set has started up in standby mode,
and the customer can switch it “on” again. When there is an
actual problem with or around the Pacific the set will go to
standby every time you try to start up. So this behaviour is an
indication of a Pacific problem.
5.8.4Ambilight
Note: in case of Ambilight protection, the set itself will not go to
protection, only the Ambilight board. When you disconnect the
set from the mains and reconnect again, the Ambilights will
work again.
5.8.6DC/DC Converter
Introduction
•Because ICs on the SSB require low supply voltages (1.2V,
2.6V, 3.3V) at high current (a few Ampères), on-board DCDC converters were implemented:
– 12V / 1V2 DC-DC converter
– extra 12V / 1V2 DC-DC converter for FPGA (only on
1080p boards)
– 12V / 2V6 DC-DC converter
– 12V / 3V3 DC-DC converter
– Vtun (+33V) generator (not for single window digital
boards)
•Startup sequence:
Apply +5V2. The standby microprocessor will begin the
start sequence.
– the STANDBY signal will go low to enable the external
supply that will deliver +12V, +8V6 and +5V to the SSB
via connector 1M46
– As soon as the +12V has its nominal value, the 12V /
1V2 DC-DC converter is enabled via ENABLE 1V2.
+1V2 should have its nominal value within miliseconds.
– If the +1V2 is ok the 12V / 2V5, 12V / 3V3 DC-DC
converters (and the Vtun generator and 12V / 1V2 DCDC converter for FPGA, if present) are enabled via
ENABLE 2V5 and ENABLE 3V3. +2V5 and +3V3 (and
Vtun and +1V2-FPGA, if it is the case) should have
their nominal values within a few miliseconds.
•There are LEDs that light up when +1V2, +2V5, +2V5D and
+3V3 are available.
•If the +12V is not available the start-up sequence is
stopped and the board enters in protection state.
•The same will happen if, further in the start-up sequence a
voltage is missing or the signal SUPPLY-FAULT remains
low.
•The signal SUPPLY-FAULT should be high (>2V) when all
DC-DC converters are working properly. The signal is
becoming active (low) when there is a defective or missing
component in any of the three DC-DC converters or the
output voltages are short-circuited to ground.
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.
5.8.5Sanken 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”).
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 possibilty 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 (see
parts list “Display Supply Sanken”). For safety reasons, make
sure to use the correct fuse type.
Fault Finding
•The best way to find a failure in the DC-DC converters is to
check their start-up sequence at power on via the mains
cord, presuming that the standby µP is operational.
•If the input voltage of the DC-DC converters is around 12V
(measured on the decoupling capacitors 2U17, 2U25 and
2U45) and the enable signals are low (active) then the
output voltages should have their nominal values.
•In case of a wrong value of the output voltages (or no
output voltage):
– Check the value of the signals (STANDBY, ENABLE
1V2, ENABLE 2V5, ENABLE 3V3 and SUPPLYFAULT)
– Check the value of the suply voltages for the IC
controllers (pin 15 of IC’s 7U04, 7U05, 7U06 and 7U64
must be +12V)
– Check the switching frequency (250 kHz) and the duty
cycle of each DC-DC converter
– Check short-circuits to GND of output voltages
5.9Software Upgrading
5.9.1Introduction
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".
EN 52FJ3.0E LA5.
Service Modes, Error Codes, and Fault Finding
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.
1) Information in column “SSB factory assy code” is only for
reference purposes. Do not use this code when ordering a new
SSB.
5.9.2Main Software Upgrade
The software image resides in the NAND-Flash, and is
formatted in the following way:
3104 328 46801
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!
5.9.3Manual 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 Standby Software Upgrade
There are two methods now to upgrade standby software:
Partition 1
Partition 0
Trimedia2 image
Trimedia1 image
MIPS image
USB Download Application
uBTM (boot block)
USB CUSTOMER
USB SERVICE
EJTAG
E_14700_082.eps
120505
Figure 5-21 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 new software can be uploaded to the set 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.
Upgrade via USB
In this chassis it is possible to upgrade standby 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 standby 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 appropreate file and press the red button to
upgrade:
Upgrade via PC and ComPair interface
It is possible to upgrade the standby software via a PC and the
ComPair interface. Check paragraph "ComPair" on how to
connect the interface. To upgrade the Standby 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 = Xon / Xoff (none*).
*Note: when having problems with upgrading, use the
values between brackets.
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
Service Modes, Error Codes, and Fault Finding
– 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. This file will be distributed via
the Service Organization.
9. After successful programming, you must see the following
info:
– 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.
