EN 5CT2.0U RA2.
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
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.
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.
-9
), or pico-farads (p= x10
-12
-6
),
).
•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
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.
Device Replacement
The last step in the repair process is to solder the new
component on the board. Ideally, the (LF)BGA should be
Page 6
EN 6CT2.0U RA2.
Safety Instructions, Warnings, and Notes
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).
G_15870_063.eps
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
100706
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: 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.
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.

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: Color bar signal.
•Audio: 3 kHz left, 1 kHz right.
5.2Service Modes
Service Default Mode (SDM) and Service Alignment Mode
(SAM) offer several features for the service technician, while
the Customer Service Mode (CSM) is used for communication
between a Customer Helpdesk and a customer.
There is also the option of using ComPair, a hardware interface
between a computer (see requirements below) and the TV
chassis. It offers the ability of structured troubleshooting, test
pattern generation, error code reading, software version
readout, and software upgrading.
Minimum requirements for ComPair: a Pentium processor,
Windows 95/98, and a CD-ROM drive (see also paragraph
“ComPair”).

corresponding to the physical channel 3.
•All picture settings at 50% (brightness, color, contrast).
•All sound settings at 50%, except volume at 25%.
•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-favorite pre-sets.
– Smart modes.
– Auto store of personal presets.
– Auto user menu time-out.
How to Activate SDM
Use one of the following methods:
•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.
•Short for a moment the two solder pads [1] on the SSB,
with the indication “SDM” (on the picture they are located
underneath the sticker). 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 “SDM and SPI service pads”.

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 (only applicable for 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 start the blinking LED procedure (not valid in protection
mode).

Contents of SAM:
•Hardware Info.
– A. VIPER SW Version. Displays the software version
of the VIPER software (main software) (example:
ED10U-1.2.3.4_12345 = AAAAB_X.Y.W.Z_NNNNN).
•AAAA= the chassis name.
•B= the region: A= AP, E= EU, L= Latam, U = US.
•X.Y.W.Z= the software version, where X is the
main version number (different numbers are not
compatible with one another) and Y is the sub
version number (a higher number is always
compatible with a lower number). The last two
digits are used for development reasons only, so
they will always be zero in official releases.
•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
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.
•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.
•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).
Service Modes, Error Codes, and Fault Finding
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 a
picture and therefore you need the correct display option. To
adapt this option, use ComPair. The correct HEX values for the
options can be found in the table below.

•With the “CURSOR LEFT/RIGHT” keys, it is possible to:
– (De) activate the selected menu item.
– (De) activate the selected submenu.
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.
Note: As long as SAM is activated, it is not possible to change
a channel. This could hamper the White Point alignments
because you cannot choose your channel/frequency any more.
Workaround: after you have sent the RC code “062596 INFO”
you will see the service-warning screen, and in this stage it is
still possible to change the channel (so before pressing the
“OK” button).

Service Modes, Error Codes, and Fault Finding
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.
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
•SW Version (example: ED10U-1.2.3.4_12345). Displays
the built-in main software version. In case of field problems
related to software, software can be upgraded. As this
software is consumer upgradeable, it will also be published
on the Internet.
•SBY Processor Version. Displays the built-in stand-by
processor software version. Upgrading this software will be
possible via a PC and a ComPair interface (see chapter
Software upgrade).
•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.
•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). Change via”MENU”, “TV”, “SOUND”,
“HEADPHONE VOLUME”.
•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 Signaling bit. If a Dolby transmission is received
without a Dolby Signaling bit, this indicator will show “OFF”
even though a Dolby transmission is received.
•Sound Mode. Indicates the by the customer selected
sound mode (or automatically chosen mode). Possible
values are “STEREO” and “VIRTUAL DOLBY
SURROUND”. Change via “MENU”, “TV”, “SOUND”,
“SOUND MODE”. It can also have been selected
automatically by signaling bits (internal software).
•Tuner Frequency. Not applicable for US sets.
•Digital Processing. Indicates the selected digital mode.
Possible values are “STANDARD” and “PIXEL PLUS”.
Change via “MENU”, “TV”, “PICTURE”, “DIGITAL
PROCESSING”.
•TV System. Gives information about the video system of
the selected transmitter.
– M: NTSC M signal received
– ATSC: ATSC signal received
•Center Mode. Not applicable.
•DNR. Gives the selected DNR setting (Dynamic Noise
Reduction), “OFF”, “MINIMUM”, “MEDIUM”, or
“MAXIMUM”. Change via “MENU”, “TV”, “PICTURE”,
“DNR”
•Noise Figure. Gives the noise ratio for the selected
transmitter. This value can vary from 0 (good signal) to 127
(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.
•Source. Indicates which source is used and the video/
audio signal quality of the selected source. (Example:
Tuner, Video/NICAM) Source: “TUNER”, “AV1”, “AV2”,
“AV3”, “HDMI 1”, “SIDE”. Video signal quality: “VIDEO”, “SVIDEO”, “RGB 1FH”, “YPBPR 1FH 480P”, “YPBPR 1FH
576P”, “YPBPR 1FH 1080I”, “YPBPR 2FH 480P”, “YPBPR
2FH 576P”, “YPBPR 2FH 1080I”, “RGB 2FH 480P”, “RGB
2FH 576P” or “RGB 2FH 1080I”. Audio signal quality:
“STEREO”, “SPDIF 1”, “SPDIF 2”, or “SPDIF”.

in normal user mode (item “signal”). In case of ATSC
receiving there will be no info displayed.
•Tuned Bit. Indicates if the selected preset is automatically
tuned (via “Automatic Installation” in the setup menu) or via
the automatic tuning system of the TV. In this case “Tuned
bit” will show “YES”. If the TV was not able to auto-tune to
the correct frequency, this item will show “NO”. So if “NO”
is displayed, it could indicate that the customer has
manually tuned to a frequency which was too far from a
correct frequency, that the TV was not able to auto-tune
any more.
•Preset Lock. Indicates if the selected preset has a child
lock: “LOCKED” or “UNLOCKED”. Change via “MENU”,

when the TV is in a protection state detected via the Stand-by
Processor (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).
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.

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
2

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!

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 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”).
•Errors detected by VIPER that lead to protection. In this
case the TV will go to protection and the front LED will blink
at 3 Hz. Further diagnosis via service modes is not possible
here (see also paragraph “Error Codes” -> “Error Buffer” > “Extra Info”).
•Errors detected by VIPER that do not lead to protection. In this case the error 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.
Note: If you encounter any problems, contact your local
support desk.
5.5Error Codes
5.5.1Introduction
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 has occurred, the error is added to the list of
errors, provided the list is not full or the error is a protection
error.
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 50+ operation hours.
9V DC
E_06532_021.eps
180804
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 stand-by processor.
•Via sensing of analogue values on the stand-by processor.
•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
•Error 1 (I
2
C bus 1 blocked). When this error occurs, the TV
will go to protection and the front LED will blink at 3 Hz.
Now you can partially restart the TV via the SDM shortcut
pins on the SSB. Depending on the software version it is
possible that no further diagnose (error code read-out) is
possible. With the knowledge that only errors 1, 2, 4, and
63 result in a 3 Hz blinking LED, the range of possible
defects is limited.
•Error 2 (I
2
C bus 2 blocked). When this error occurs, the
TV will go to protection and the front LED will blink at 3 Hz.
Now you can partially restart the TV via the SDM shortcut
pins on the SSB. Due to hardware restriction (I
the fast I
2
C bus) it will be impossible to start up the VIPER
2
C bus 2 is
and therefore it is also impossible to read out the error
codes via ComPair or via the blinking LED method. With
the knowledge that only errors 1, 2, 4, and 63 result in a 3
Hz blinking LED, the range of possible defects is limited.
When you have restarted the TV via the SDM shortcut pins,
and then pressed "CH+" on your remote control, the TV will
go to protection again, and the front LED blink at 3 Hz
again. This could be an indication that the problem is
related to error 2.
•Error 3 (I
on I
2
C bus 3 blocked). There are only three devices
2
C 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 be logged when the NVM gives
no acknowledge on the I
2
C bus (see error 44). Note that if
the 12 V supply is missing (connector 1M46 on the SSB),
the DC/DC supply on the SSB will not work. Therefore the
VIPER will not get supplies and could block I
a missing 12 V can also lead to an error 3.
•Error 4 (I

•Error 7 (8.6 V error). Except a physical problem with the
8.6 V itself, it is also possible that there is something wrong
with the Audio DC Protection: see paragraph "Hardware
Protections" for this.
•Error 12 (12 V error). Except a physical problem with the
12 V itself, it is also possible that there is something wrong
with the Audio DC Protection: see paragraph "Hardware
Protections" for this.
•Error 14 (Audio supply). This error is triggered in case of
too low voltage of the audio supplies and therefore a drop
of the audio supply voltage of below approx. 9 V per supply
rail (or lower than 18 V rail to rail). Also a DC voltage of
higher than 1 V DC on the speakers will lead to protection
and error 14 blinking. For LCD sets this circuit can be found
on schematic SA3, for PDP sets this can be found on
schematic C. It should be noted that for 26-inch models
there is only a supply link between the amplifiers and the
stand-by µC whereas in all other models this link is
implemented by Audio-Prot line pin 7 on 1 M02.
•Error 29 (AVIP1). This error will probably generate extra
errors. You will probably also see errors 32 (MPIF) and
error 31 (AVIP 2). Error 29 and 31 will always be logged
together due to the fact that both AVIPs are inside the
PNX2015 and are on the same I
2
C bus. In this case start
looking for the cause around AVIP (part of PNX2015).
•Error 31 (AVIP2). See info on error 29.
•Error 34 (Tuner 1). When this error is logged, it is not sure
that there is something wrong with the tuner itself. It is also
possible that there is something wrong with the
communication between channel decoder and tuner. See
schematic B2B.
•Error 37 (Channel decoder). This error will always log
error 34 (tuner) extra. This is due to the fact that the tuner
2
I
C bus is coming from the channel decoder.
•Error 44 (NVM). This error will never occur because it is
masked by error 3 (I
for error 3 checks on an I
2
C bus 3). The detection mechanism
2
C 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 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).
5.6The Blinking LED Procedure
5.6.1Introduction
The blinking LED procedure can be split up into two situations:
Page 24
EN 24CT2.0U RA5.
Service Modes, Error Codes, and Fault Finding
•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 9 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. 9 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.
Protections during Start-up
During TV start-up, some voltages and IC observers are
actively monitored to be able to optimize 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 is one hardware protection in this chassis: “Audio DC
Protection”. This protection occurs when there is a DC voltage
on the speakers. In that case the main supply is switched "off",
but the stand-by supply is still working.
For the Samsung V4 PDP displays, the 8V6 supply is switched
"off" and the LED on the display’s Main Supply blinks eleven
times, which means there is an overvoltage protection. The
front LED of the TV will blink error 7 (8V6 error).
In case of LCD supplies, the 12V supply will drop. This will be
detected by the stand-by processor, which will start blinking the
12 V error (error 12).
Repair Tip
•It is 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 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, +2.5V 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 anymore.
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.

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

5.8.4DC/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/AC Power cord, presuming that the Stand-by
Processor is operational.
•If the input voltage of the DC/DC converters is around 12 V
(measured on the decoupling capacitors 2U17/2U25/
2U45) and the ENABLE signals are "low" (active), then the
output voltages should have their normal values.
•First, the Stand-by Processor activates the +1V2 supply
(via ENABLE-1V2).
•Then, after this voltage becomes present and is detected
OK (about 100 ms), the other two voltages (+2V5 and
+3V3) will be activated (via ENABLE-3V3).
•The current consumption of controller IC 7U00 is around 20
mA (that means around 200 mV drop voltage across
resistor 3U22).
•The current capability of DC/DC converters is quite high
(short-circuit current is 7 to 10 A), 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, the +3V3 will not have the normal value
but much less.
•The supply voltage +12VSW is protected for over-currents
by fuse 1U04.
•Symptom: +1V2 present for about 100 ms. Supplies +2V5
and +3V3 not rising.
1. Check the ENABLE-3V3 signal (active "low").
2. Check the voltage on pin 8 (1.5 V).
3. Check the under-voltage detection circuit (the voltage
on collector of transistor 7U10-1 should be less than
0.8 V).
4. Check for output voltages short-circuits to GND (+3V3,
+2V5 and +2V5D) that generate pulsed over-currents
of 7-10 A through coil 5U00.
5. Check the over-current detection circuit (2U18 or 3U83
interrupted).
•Symptom: +1V2 OK, but +2V5 and +3V3 present for about
100 ms. Cause: The SUPPLY-FAULT line stays "low"
even though the +3V3 and +1V2 is available. The Stand-by
Processor is detecting that and switches all supply
voltages "off".
1. Check the drop voltage across resistor 3U22 (this
could be too high)
2. Check if the +1V2 or +3V3 are higher than their normal
values. This can be due to defective DC feedback of
the respective DC/DC converter (3U18 or 3UA7).
•Symptom: +1V2, +2V5, and +3V3 look okay, except the
ripple voltage 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.
– Check resistor 3U06, the decoupling capacitors, the
AC feedback circuits (2U20 + 2U21 + 3U14 + 3U15 for
+1V2 or 2U19 + 2U85 + 3U12 + 3U13 for +3V3), the
compensation capacitors 2U09, 2U10, 2U23 and
2U73, and IC 7U00.
Note 1: If fuse 1U01 is broken, this usually means a pair of
defective power MOSFETs (7U01 or 7U03). Item 7U00 should
be replaced as well in this case.
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 (1.5 V).
3. Check for +1V2 output voltage short-circuit to GND that
can generate pulsed over-currents 7-10 A through coil
5U03.
4. Check the over-current detection circuit (2U12 or 3U97
interrupted).

5.9Software Upgrading
5.9.1Introduction
The set software and security keys are stored in a NAND-Flash
(item 7P80), 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
standalone set, without the need of an E-JTAG debugger. A
description on how to upgrade the main software can be found
in the "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!!! 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 menu 5 if the HDMI and POD keys are valid.

Note: After replacing the SSB, execute the alignments
according to the instructions in this manual.

Executables are stored as files in a file system. The boot loader
(uBTM) will load the USB Download Application in partition 0
(USB drivers, bootscript, 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 TV by using a
portable memory device or USB storage compliant devices
(e.g. USB memory stick). You can download the new software

To upgrade this “USB download application” (partition 0 except
the bootblock), insert an USB stick with the correct software,
but 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!
5.9.3Manual Start of the Main 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.
5.9.4Stand-by Software Upgrade
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 “SDM and SPI service
pads” earlier in this chapter).
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
– Data bits = 8
– Parity = none
– Stop bits = 1
– Flow control = Xon / Xoff.
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. This file will be distributed via
the Service Organization.
9. After successful programming, you must see the following
info:
– DCSUM=0xECB3
–:Ok
– MCSUM=0xECB3
Page 33
Service Modes, Error Codes, and Fault Finding
– 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.

Perform all electrical adjustments under the following
conditions:
•Power supply voltage: 120 V
•Connect the set to the AC Power via an isolation
transformer with low internal resistance.
•Allow the set to warm up for approximately 15 minutes.
•Measure voltages and waveforms in relation to chassis
ground (with the exception of the voltages on the primary
side of the power supply).
Caution: It is not allowed to use heatsinks as ground.
•Test probe: Ri > 10 Mohm, Ci < 20 pF.
•Use an isolated trimmer/screwdriver to perform
alignments.
8.1.2Initial Settings
Perform all electrical adjustments with the following initial
settings (via the "Active Control" button on the RC):
1. To avoid the working of the lightsensor, set ACTIVE
CONTROL to OFF (if present).
2. Set SMART PICTURE to NATURAL/ECO.
8.1.3Alignment Sequence

9. Select the test pattern with 5 % overscan.
Note: If this test pattern is not available, use the pattern
provided by the Service Alignment Menu -> DLP Menu ->
DLP Setting -> Test Pattern.
10. Manipulate the light engine mounting bracket [5], and see
what happens in terms of size and distortion of the image
on-screen. Note, that you can slide the bracket sideways
on both front and rear side, and that you can lift and turn it
at the rear side.
11. Determine the optimum position for the light engine,
constantly evaluating the quality of the image on-screen.
12. Fixate the light engine in this position with screws [3] and
[4]. If necessary fine tune by turning screws [3]. Note, that
screwing clockwise lifts the mounting bracket, but when
you screw counterclockwise you need to push the bracket
downwards.
13. Re-evaluate and if necessary readjust.
14. Tighten screws [1] and nuts [2].
15. Seal screws [1] and [3], and nuts [2].

•First, set the correct options:
– In SAM, select (SERVICE) OPTIONS -> OPT. NO,
– Fill in the option settings according to the set sticker
(see also paragraph "Option Settings"),
– Select STORE OPTIONS and push OK on the remote
control,
– After storing, the set must be restarted!
•Warming up (>10 minutes).
•White point alignment.
8.2Hardware Alignments
8.2.1Light Engine
Introduction
In case the image on the screen is distorted, it can be adjusted
with the light engine. As this adjustment can be complicated,
only perform it when absolutely necessary.
Execution
1. Remove the rear cover, as described previously.
2. Loosen screws [1].
3. Loosen nuts [2].
4. Loosen screws [3].
5. Use a 25 cm (10”) long 4 mm allen key, to loosen the
screw, that you can reach through hole [4]. Loosen the
screw just far enough to facilitate the sideways movement
of the light engine (1 - 2 turns).
6. Make sure you can see the whole screen, while
manipulating the light engine. E.g. by putting the set in front
of a large mirror.
7. Switch on the set. Let it warm up for at least 30 seconds.
8. Connect a USB-stick with the appropriate test patterns to
the side I/O (can be downloaded from the service website).

8.3Software Alignments
Put the set in SAM mode (see the "Service Modes, Error Codes
and Fault Finding" section). The SAM menu will now appear on
the screen. Select ALIGNMENTS and go to one of the sub
menus. The alignments are explained below.
Notes:
•All changes must be stored manually.
•If an empty EAROM (permanent memory) is detected, all
settings are set to pre-programmed default values.
8.3.1 General
For the next alignments, supply the following test signals via a
video generator to the RF input: NTSC M/N TV-signal with a
signal strength of at least 1 mV and a frequency of 61.25 MHz
(channel 3).
Tuner AGC
Purpose: To keep the tuner output signal constant as the input
signal amplitude varies.
For this chassis, no alignment is necessary, as the AGC
alignment is done automatically (standard value: “32”).
8.3.2White Point
1. Select a COLOUR TEMPERATURE (e.g. COOL,
NORMAL, or WARM).
2. Set the RED, GREEN and BLUE default values according
to the values in the "Tint settings" table.
3. When finished press STORE (in the SAM root menu) to
store the aligned values to the NVM.
4. Restore the initial picture settings after the alignments.

•Set ACTIVE CONTROL to OFF (if present).
•In the [MENU] -> PICTURE user menu, set:
– DYNAMIC CONTRAST to OFF.
– COLOUR ENHANCEMENT to OFF.
– COLOUR to "50".
– CONTRAST to "100".
– BRIGHTNESS to "50".
•Go to the SAM and select ALIGNMENTS -> WHITE
POINT.
Method 1 (with color analyzer):
•Use a 100% white screen as input signal and set the
following values:
– COLOR TEMPERATURE: "Tint to be aligned".
– All WHITE POINT values to: "127".
– RED BL OFFSET value to: "9".
– GREEN BL OFFSET value to: "8".
•Measure with a calibrated (phosphor- independent) color
analyzer in the centre of the screen. Consequently, the
measurement needs to be done in a dark environment.
•Adjust, by means of decreasing the value of one or two
white points, the correct x,y coordinates (see table "White
D alignment values"). Tolerance: dx,dy: ± 0.004.
•Repeat this step for the other Color Temperatures that
need to be aligned.
•When finished press STORE (in the SAM root menu) to
store the aligned values to the NVM.
•Restore the initial picture settings after the alignments.

When such equipment is not available, use “method 2”.
Method 2 (without color analyzer):
If you do not have a color analyzer, you can use the default
values. This is the next best solution. The default values are
average values coming from production (statistics).

Select this sub menu to set all options at once (expressed in
two long strings of numbers).
An option number (or "option byte") represents a number of
different options. When you change these numbers directly,
you can set all options very quickly. All options are controlled
via eight option numbers.
When the EAROM is replaced, all options will require resetting.
To be certain that the factory settings are reproduced exactly,
you must set both option number lines. You can find the correct
option numbers on a sticker inside the TV set.

•00016 00000 00033 14979
•00038 00000 00544 00000
Every 5-digit number represents 16 bits (so the maximum value
will be 65536 if all options are set).
When all the correct options are set, the sum of the decimal
values of each Option Byte (OB) will give the option number.
The first line (group 1) indicates hardware options 1 to 4, the
second line (group 2) indicates software options 5 to 8.

The description below refers to the block diagrams in chapter 6
“Block Diagrams, Test Point Overview, and Waveforms”.
Analog Reception
The TV receives multimedia information by tuning the Hybrid
tuner (for analog and digital reception) to one of many 6 MHz
input channels available via a cable connection. When the
input channel is an analog channel, the signal is processed via
the NTSC decoder and the VBI data decoder of the MPIF.
Digital Reception
The TV receives multimedia information by tuning to one of
many 6 MHz input channels available via a cable connection.
When the input channel is a digital channel, it is processed via
the QAM demodulator and then passed to the multi-media
processor (VIPER), which handles the synchronization and
display of audio-visual material.
Signal Processing
The AVIP together with the MPIF device is used to perform the
input decoding of a single stream of analog audio and video
broadcast signals. In addition, the AVIP is used for decoding
and presentation of audio output streams. The main data
connection between MPIF and AVIP is done via an I
2
D bus.
The AVIP converts the incoming video data to ITU-656 format
for communication to the VIPER IC.
The audio data is transferred between the AVIP and VIPER
2
using I
S.
The AVIP IC is controlled by the VIPER via the I
2
C bus.
The key part in the system, the VIPER, performs almost all key
features, like video quality enhancement, motion
compensation, picture-in-picture processing, and others. It is a
completely digital IC with a TriMedia DSP (Digital Signal
Processor) core and a MIPS microcontroller core. The DSP
and some additional cores are used to do the video feature
processing and some auxiliary sound feature processing. The
