Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
EN 5FTL2.1, FTL2.2E AA2.
Index of this chapter:
2.1 Safety Instructions
2.2 Warnings
2.3 Notes
2.1Safety Instructions
Safety regulations require the following during a repair:
•Connect the set to the Mains (AC Power) via an isolation
transformer (> 800 VA).
•Replace safety components, indicated by the symbol h,
only by components identical to the original ones. Any
other component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay in particular attention to
the following points:
•Route the wire trees correctly and fix them with the
mounted cable clamps.
•Check the insulation of the Mains (AC Power) lead for
external damage.
•Check the strain relief of the Mains (AC Power) cord for
proper function.
•Check the electrical DC resistance between the Mains (AC
Power) plug and the secondary side (only for sets that have
a Mains (AC Power) isolated power supply):
1. Unplug the Mains (AC Power) cord and connect a wire
between the two pins of the Mains (AC Power) plug.
2. Set the Mains (AC Power) switch to the "on" position
(keep the Mains (AC Power) cord unplugged!).
3. Measure the resistance value between the pins of the
Mains (AC Power) plug and the metal shielding of the
tuner or the aerial connection on the set. The reading
should be between 4.5 Mohm and 12 Mohm.
4. Switch "off" the set, and remove the wire between the
two pins of the Mains (AC Power) plug.
•Check the cabinet for defects, to prevent touching of any
inner parts by the customer.
2.2Warnings
•All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD w). Careless handling
during repair can reduce life drastically. Make sure that,
during repair, you are connected with the same potential as
the mass of the set by a wristband with resistance. Keep
components and tools also at this same potential. Available
ESD protection equipment:
– Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and earth cable) 4822
310 10671.
– Wristband tester 4822 344 13999.
•Be careful during measurements in the high voltage
section.
•Never replace modules or other components while the unit
is switched "on".
•When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a
circuit becoming unstable.
2.3Notes
2.3.1General
•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 stand-by (F). These values are
indicated by means of the appropriate symbols.
•The semiconductors indicated in the circuit diagram and in
the parts lists, are interchangeable per position with the
semiconductors in the unit, irrespective of the type
indication on these semiconductors.
•Manufactured under license from Dolby Laboratories.
“Dolby”, “Pro Logic” and the “double-D symbol”, are
trademarks of Dolby Laboratories.
2.3.2Schematic 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.

),
).
EN 6FTL2.1, FTL2.2E AA3.
Directions for Use
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.

Information 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 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.
•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.
E_06532_024.eps
230205
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.
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 the
mixing of two alloys).
Caution: For BGA-ICs, you must use the correct temperature
profile, which is coupled to the 12NC. For an overview of these
profiles, visit the website www.atyourservice.ce.philips.com
(needs subscription, but is not available for all regions).
You will find this and more technical information within the
"Magazine", chapter "Workshop information".
For additional questions please contact your local repair help
desk.
2.3.5Practical 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.
3.Directions for Use
You can download this information from the following websites:
•Figures below can deviate slightly from the actual situation,
due to the different set executions.
•Follow the disassemble instructions in described order.
•As this chassis has two different mecanical stylings, the
dismantle instructions are splitted in two parts: one for the
“Top” version and one for the “Wrap” version.
For easy servicing of this set, there are a few possibilities
created:
•The buffers from the packaging (see figure "Rear cover").
•Foam bars (created for service).
•Aluminium service stands (created for Service).
4.2.1Foam Bars
E_06532_018.eps
Figure 4-3 Foam bars
The foam bars (order code 3122 785 90580 for two pieces) can
be used for all types and sizes of Flat TVs. By laying the TV
face down on the (ESD protective) foam bars, a stable situation
is created to perform measurements and alignments.
By placing a mirror under the TV, you can monitor the screen.

Contents of SAM:
•OPERATION HOURS. Displays the accumulated total of
operation hours (not the stand-by hours).
•HARDWARE INFO.
– ROM VERSION. Displays the date of the software and
the software version of the ROM
(example: TX21EU_1.0_01234 =
AAAABB_X.Y_NNNNN).
•AAAA= the chassis name.
•BB= the region: EU= Europe, AP= Asia Pacific
PAL/Multi, AN= Asia Pacific NTSC, US= USA, LT=
LATAM.
•X.Y= 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).
•NNNNN= last five digits of 12nc code software.
– FBX Version. Displays the software version of the
FBX
– SW VERSION EPLD. Displays the software version of
the EPLD.
•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 the “OK”
button, the error buffer is reset.
•ALIGNMENTS. This will activate the “ALIGNMENTS” submenu.
•DEALER OPTIONS. Extra features for the dealers.
•SERVICE OPTIONS. Extra features for Service.
•INITIALISE NVM. When an NVM was corrupted (or
replaced) in the former EM3 chassis, the microprocessor
replaced the content with default data (to assure that the
set can operate). However, all pre-sets 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 recognises a corrupted NVM, the “initialise
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 initialising. This will give
the Philips Service department an extra possibility for
diagnosis (e.g. when Development asks for this).
– Initialise the NVM (same as in the past, however now it
happens conscious).
•STORE. All options and alignments are stored when
pressing the “OK”-button
•FUNCTIONAL TEST. All devices are tested via the “OK”
button. Eventual errors are displayed in the error buffer.
The error buffer is not erased, the content returns when this
test is terminated.
•DAILY MENUS. With the “OK” button, you can go to the
normal user menu. SAM is still active in the background.
With the “MENU” button, you return from the user menu to
SAM menu. This feature can be helpful to quickly change
some settings in the user menu.
•SW MAINTENANCE.
•UPGRADE. More info see paragraph Software
downloading.
•EVENTS. Not useful for Service purposes. In case of
specific software problems, the development
department can ask for this info.
•BDM INFO. Broadcast Debug Menu info. The purpose
of this menu is to debug the broadcast, not the TV. The
menu gives an overview of what is received on the
current preset.

5.2.3Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer. The service technician can than 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
Use one of the following methods:
•Press the “MUTE” button on the RC-transmitter
simultaneously with the “MENU” button on the TV (top
control) for at least 4 seconds.
•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.

5.4ComPair
For this chassis, the ComPair interface box and the TV
communicate via a bi-directional service cable via the service
connector.
The ComPair fault finding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:
•Automatic (by communication with the television): ComPair
can automatically read out the contents of the entire error
buffer. Diagnosis is done on I
2
the I
C bus of the television. ComPair can send and
receive I
2
C commands to the micro controller of the
television. In this way, it is possible for ComPair to
communicate (read and write) to devices on the I
2
C level. ComPair can access
2
C buses
of the TV-set.
•Manually (by asking questions to you): Automatic
diagnosis is only possible if the micro controller of the
television is working correctly and only to a certain extends.
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.
Beside fault finding, ComPair provides some additional features like:
•Up- or downloading of pre-sets.
•Managing of pre-set lists.
•Emulation of the Dealer Service Tool (DST).
•If both ComPair and SearchMan (Electronic Service
Manual) are installed, all the schematics and the PWBs of
the set are available by clicking on the appropriate
hyperlink.
Example: Measure the DC-voltage on capacitor C2568
(Schematic/Panel) at the Mono-carrier.
– Click on the “Panel” hyperlink to automatically show
the PWB with a highlighted capacitor C2568.
– Click on the “Schematic” hyperlink to automatically
show the position of the highlighted capacitor.
5.4.1Introduction
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:
•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.
•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.
•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 SearchMan electronic manual of the defective chassis,
schematics and PWBs are only a mouse click away.
5.4.2Specifications
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 RS232 cable.

C level) and
2
C commands
5.4.3Stepwise Start-up
Under normal circumstances, a fault in the power supply, or an
error during start-up, will switch the television to protection
mode. ComPair can take over the initialisation of the television.
In this way, it is possible to distinguish which part of the startup routine (hence which circuitry) is causing the problem.
Take notice that the transition between two steps can take
some time, so give the set some time to reach a stable state.
During the transition time, the LED can blink strangely.
Stepwise start- up explanation
This is realised via ComPair and is very helpful when a
protection is activated (see also chapter “Protections”). The
following diagram shows the start-up procedure of the set.
Every step of the stepwise start-up (also called trapped startup) in the diagram corresponds with the number of times the
led blinks.

5.4.4How To Connect
This is described in the chassis fault finding database in
ComPair.
• When the set is in stepwise mode and, due to stepping-up,
a protection is activated, the set will really go into protection
(blinking LED). The set will not leave the stepwise-mode
however. If state X is the state where the set went to
protection, stepwise start-up will return to state X-1. At
state (X-1) diagnostic measurements can be performed.
Also, in the short time the set is in state X but not yet in
protection, you can also do some measurements.

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.
When multiple errors occur (errors occurred within a short time
span), there is a high probability that there is some relation
between them.
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).
Examples:
– 0 0 0 0 0: No errors detected
– 6 0 0 0 0: Error code 6 is the last and only detected
error
– 9 6 0 0 0: 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.
Service Modes, Error Codes, and Fault Finding
EN 19FTL2.1, FTL2.2E AA5.
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”.
•When you transmit the commands “DIAGNOSE” - “99” “OK” with ComPair (or with a DST).
•If the content of the error buffer has not changed for 50+
hours, it resets automatically.
5.5.4 Error Codes
In case of non-intermittent faults, clear the error buffer before
you begin the repair. This to ensure that old error codes are no
longer present. Before clearing the buffer, write down the
content, as this history can give you significant information.
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 various errors:
2
•I
C device errors.
2
•I
C bus errors.
•Protection errors.
•Errors not related to an I
2
C device, but of importance:
– FEM (Falconic with Embedded Memory) (Error 26):
at start-up, after initialisation of the PICNIC, the
presence of the FEM can be checked.
– Eagle (Error 27): at start-up, after initialisation of the
PICNIC, the presence of the Eagle can be checked.

Note:
•Error codes 1, 6, or 18 are protection codes and in this
case, supplies of some circuits will be switched “off”. Also,
in protection, the LED will blink the number of times
equivalent to the most recent error code.
EN 20FTL2.1, FTL2.2E AA5.
Service Modes, Error Codes, and Fault Finding
5.6The Blinking LED Procedure
5.6.1Introduction
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 SDM is activated, the front LED will show (blink) the
contents of the error-buffer. Error-codes > 10 are shown as
follows:
– A long blink of 750 ms (which is an indication of the decimal
digit),
– A pause of 1.5 s,
– “n” short blinks (where “n” = 1 - 9),
– When all the error-codes are displayed, the sequence
finishes with a LED blink of 3 s,
– The sequence starts again.
Example: Error 12 9 6 0 0.
After activation of the SDM, the front LED will show:
– 1 long blink of 750 ms (which is an indication of the decimal
digit) followed by a pause of 1.5 s,
– 2 short blinks followed by a pause of 3 s,
– 9 short blinks followed by a pause of 3 s,
– 6 short blinks followed by a pause of 3 s,
– 1 long blink of 3 s to finish the sequence,
– The sequence starts again.
Note: If errors 1, 6, or 18 occur, the LED always gives the last
occurred error even if the set is NOT in service mode.
5.6.2How to Activate
Use one of the following methods:
•Activate the SDM (only via soldering pads marked “SDM”
on SSB). The blinking front LED will show the entire
contents of the error buffer (this works in “normal
operation” mode and in “protection” 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.
•“DIAGNOSE X” with the DST (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.... When x = 0 all
errors are shown.
5.7Protections
5.7.1Introduction
This chassis has only one microprocessor (OTC), which
remains active during Stand-by. This because power of the
microprocessor and the attached memory chip set is coming
from the 3V3 supply, which is derived from the 5V Stand-bycircuitry. Therefore, in both Power-on as in Stand-by mode, the
microprocessor is connected to this power supply.
If a fault situation is detected, an error code will be generated
and if necessary, the set is put in protection mode. The
protection mode is indicated by the blinking of the front LED at
a frequency of 3 Hz (or by a coded blinking in special cases).
The content of the error buffer can be read via the service menu
(SAM), the blinking LED procedure or via DST/ComPair.
To get a quick diagnosis, this chassis has three service-modes
implemented:
•The Customer Service Mode (CSM).
•The Service Default Mode (SDM). Start-up of the set in a
predefined way.
•The Service Alignment Mode (SAM). In this mode, items
of the set can be adjusted via a menu.
You can activate both SDM and SAM modes via the “service
pads” on the SSB, via an RC-transmitter (DST or standard RC),
or via ComPair. It is not possible to activate the SAM in “standby”; the TV has to be in “normal operation” mode.
The “Protection Diagram” shows the structure of the protection
system. See diagram below.

There are several types of protections:

•I
C related protections.
•OTC related protections (via polling on I/O pins or via
algorithms).
•Hardware protection
All protections are explained below.

occur, if the power supply of the IC is missing.
DC/DC protection: When a 3V3 supply is short-circuited, the
DC/DC converter switches “off” and goes in protection. The
FBX, EPLD IC, and 3D comb IC have no supply voltage and
give no acknowledge. In this case, the set should go into
protection. An error code is written in the NVM: DC/DC error.
FBX protection: the FBX protection is not available any more.
It is replaced by the DC/DC protection.
5.7.3 OTC Related Protections
If a protection is detected at an OTC input, the OTC will start to
scan all protection inputs every 200 ms for 5 times. If the
protection on one of the inputs is still active after 1 s, the
microprocessor will put the set in the protection mode. Before
the scanning is started, a so-called “ESD refresh” is carried out.
This is done, because the interrupt on one of the inputs is
possibly caused either by a flash or by ESD. As a flash or ESD
can influence IC settings, the HIP, MSP, 3D Comb and wireless
module (not used in this set) are initialised again, to ensure the
normal picture and sound conditions of the set.

8 V and 5 V protections: The microprocessor senses the
presence of the 8 V and 5 V (via the “+5V_CON” and
“+8V_CON” lines). If one (or both) of these voltages is (are) not
present, an error code is stored in the error buffer of the NVM,
and the set is put in the protection mode.
Audio DC protection: The OTC senses if the audio module is
in protection via IRQ-DIGITAL (pin 98 of OTC). If this is the
case, the OTC puts the set in protection.
5.7.4 Hardware Protection
Short-circuiting the 3V3 supply from the DC/DC converter will
shut down the DC/DC converter. The absence of the 3V3
supply line is also sensed via I
2
C (see description DC/DC
protection above), this is useful if there is something wrong in
the detection circuit of the DC/DC converter. There are no
hardware protections in this chassis, which switch off the main
supply.
5.8Repair tips
5.8.13V3 Supply (DC/DC converter)
As mentioned above, the DC/DC converter is switched “off”
when something goes wrong (detection of a missing 3V3
supply at one of the devices supplied by the 3V3). Because of
this, the set goes to protection (I
logged.
For further diagnoses, you need to overrule the I
put the set in Service Default Mode by means of the solder
pads on the SSB.
The DC/DC converter is still not working because it is switched
“off” by the 3V3_FAULT line (schematic B12). Now you have
some possibilities:
1. First, measure the impedance over diode 6U06. In normal
conditions, you should measure approximately 120 ohm (if
possible, verify this with another set). If the impedance is
much too low, do not try to start up the converter as
mentioned below. Remind that if FET 7U03 is shortcircuited, this will also influence your measurement.
2. Desolder coils 5U05 and 5U06, connect an external 3V3
supply at capacitor 2U23 (current limitation to 500 mA) and
a second external 3V3 supply at capacitor 2U31 (current
limitation to 800 mA). The normal working current of the
3V3_SIM line is approximately 400 mA and the normal
working current for the 3V3_DCDCFBX line is
approximately 700 mA. Therefore, if one of the currents
exceeds their nominal value you can determine in which
circuit the overload is situated. If the set would start up and
you have normal picture, there is probably no overload but
a problem in the detection circuits.
3. If you do not have two external power supplies, you can do
the following: Desolder coils 5U02, 5U03, and 5U04 (you
must desolder all three, otherwise the circuit could be
damaged), connect an external power supply of 3V3 at the
cathode of diode 6U06. Make sure to limit the current of this
external supply to approximately 1200 mA. If the supplied
current exceeds 1100 mA (approximately normal working
current) you can conclude that one of the devices supplied
by 3V3 is short-circuited.
4. Another possibility is to force the converter to start up by
short-circuiting (and keep short-circuited) resistor 3U25
(B12).
Caution: Be aware that this can damage the set. Even if
you measure approximately 120 ohm over diode 6U06,
there can still be something wrong in the converter itself.
By short-circuiting resistor 3U25, the internal protection of
the converter is disabled.

C protection:
5.8.2ComPair
This chassis does not have an IR transmitting LED (as in MGsets). Therefore, a “Service” (ComPair) connector is
implemented at the rear side of the set, which is directly
accessible. In addition to this, there is also a blinking LED
procedure to show the contents of the error buffer.
When you use ComPair, you have the possibility to activate a
“stepwise start-up” mode. With this mode, you can initiate the
start-up sequence step by step. This also means that in certain
steps, some protections are not activated. This is sometimes
very convenient during repair.
5.8.3Protections
Activating SDM via the “service pads” will overrule the
processor-controlled protections, but not the hardware
protections. This means, that the A/D-input protections (5 and
8 V) and the I

5.9Software Downloading
In this chassis, you can upgrade the Main software via
ComPair without removing the back cover of the set (it is
possible that early production sets don’t have a hole in the back
plate, in this case you have to remove the back plate). The
switch (see figure “Service pads”), which is needed for the
software downloading procedure, can be reached through a
gap in the back cover or the SSB shielding. The switch can be
operated with a toothpick or something like that. Make sure that
you do not damage the PWB with sharp objects. You can find
more information on how this procedure works in the ComPair
file. It is possible that not all sets are equipped with the
hardware, needed to make software upgrading possible. To
speed up the programming process the firmware of the
ComPair interface can be upgraded. See paragraph “How To
Order” for the order numbers.
