Safety Instructions, Warnings, And Notes

2. Safety Instructions, Warnings, And Notes

EN 5FTL2.4A AA 2.

Index of this chapter:

2.1 Safety Instructions

2.2 Warnings

2.3 Notes

2.1 Safety 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.

2.2 Warnings

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.

2.3.2 Schematic Notes

• All resistor values are in ohms, and the value multiplier is
often used to indicate the decimal point location (e.g. 2K2
indicates 2.2 kohm).

• Resistor values with no multiplier may be indicated with
either an "E" or an "R" (e.g. 220E or 220R indicates 220
ohm).

• All capacitor values are given in micro-farads (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.

2.3.3 Rework on BGA (Ball Grid Array) ICs

General

Although (LF)BGA assembly yields are very high, there may
still be a requirement for component rework. By rework, we
mean the process of removing the component from the PWB
and replacing it with a new component. If an (LF)BGA is
removed from a PWB, the solder balls of the component are
deformed drastically so the removed (LF)BGA has to be
discarded.

-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.

2.3 Notes

2.3.1 General

• Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the tested area of circuitry. The voltages and waveforms
shown in the diagrams are indicative. Measure them in the

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

EN 6 FTL2.4A AA3.

Directions For Use

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.

2.3.4 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).

– 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

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.

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 "Workshop information".
For additional questions please contact your local repair help
desk.

2.3.5 Practical Service Precautions

• It makes sense to avoid exposure to electrical shock.
While some sources are expected to have a possible
dangerous impact, others of quite high potential are of
limited current and are sometimes held in less regard.

• Always respect voltages. While some may not be
dangerous in themselves, they can cause unexpected
reactions that are best avoided. Before reaching into a
powered TV set, it is best to test the high voltage insulation.
It is easy to do, and is a good service precaution.

• Audio: 3 kHz left, 1 kHz right.

5.2 Service 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 Philips Customer Care Centre (P3C) 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: a Pentium processor, Windows 95/
98, and a CD-ROM drive (see also paragraph “ComPair”).

Remark: The silk screen printing is not correct for the SAM/
SDM indication. For the correct location of these pins, see
figure ”Service pads”.

• Software alignments.

How To Activate SAM

Use one of the following methods:

• Via a standard RC transmitter: key in the code “062596”
directly followed by the “OSD [i+]” button. After activating
SAM with this method a service warning will appear on the
screen, you can continue by pressing any digit key on the
RC.

• Short for a moment the two solder pads on the SSB with
the indication "SAM" (see figure ”Service pads”).
Depending on the software version, it is possible that a
service warning will appear. You can continue by pressing
any digit key on the RC.

• Use the DST-emulation feature of ComPair.

• Press the ALIGN button on the DST while the TV is in the
normal operation

After activating this mode, “SAM” will appear in the upper right
corner of 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
Ex.: TX24EU_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. 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).
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. This
code can be found on the option code sticker inside the set.

• 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.

the TV. 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 the following method:
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!

5.3 Problems And Solving Tips (Related To CSM)

Note: Below described problems are all related to the TV

settings (visible in the CSM menu). The procedures to change
the value (or status) of the different settings are described
above. New value(s) are automatically stored.

5.3.1 Picture Problems

Snowy/Noisy Picture

1. Check in CSM line NOISE FIGURE. In case the value is
"127" or higher, and the value is also high on other
programs, check the aerial cable/aerial system. For some
software versions, the noise figure will only be valid when
“Active Control” is set to “medium” or “maximum”.

2. Check in CSM lines SHARPNESS and NOISE FIGURE. In
case the value of line SHARPNESS is "3" or "4" and the
value of line NOISE FIGURE is high ("127" or higher),
decrease the "Sharpness” value.

Picture Too Dark

5.4 Service Tools

5.4.1 ComPair

Introduction

ComPair (Computer Aided Repair) is a service tool for Philips
Consumer Electronics products. ComPair is a further
development on the European DST (service remote control),
which allows faster and more accurate diagnostics. ComPair
has three big advantages:

1. ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you
systematically through the repair procedures.

2. ComPair allows very detailed diagnostics (on I
is therefore capable of accurately indicating problem areas.
You do not have to know anything about 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:

• Automatic (by communication with the television): ComPair
can automatically read out the contents of the entire error

Stepwise 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.

5.4.2 LVDS Tool

Introduction

This service tool (also called “ComPair Assistant 1“) may help
you to identify, in case the TV does not show any picture,
whether the Small Signal Board (SSB) or the display of a Flat
TV is defective.
Furthermore it is possible to program EPLDs with this tool
(Byteblaster). 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).

Tact switch

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 (>= 1280x768). Generally this tool is intended to
determine if the SSB is working or not. Thus to determine if
LVDS, RGB, and sync signals are okay.

How To Connect

Connections are explained in the user manual, which is
delivered 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.

Note: When the set is in stepwise mode and, due to stepping-

(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.

5.5 Error Codes

5.5.1 Introduction

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.

5.5.2 How 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.

EN 18 FTL2.4A AA5.

Service Modes, Error Codes, And Fault Finding

5.5.3 How To Clear The Error Buffer

Use one of the following methods:

• By activation of the “RESET ERROR BUFFER” command
in the SAM menu.

• With a normal RC, key in sequence “MUTE” followed by
“062599” and “OK”.

• 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:

•I

C device errors.

•I

C bus errors.

• Protection errors.

• Errors not related to an I

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 19FTL2.4A AA 5.

5.6 The Blinking LED Procedure

5.6.1 Introduction

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.

Note: For error codes >100, the first two digits (hundred-and­ten) are considered as one digit (one long blink)

Example: Error 12 9 6 121 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,
– 12 long blinks of 750 ms (which is an indication of “120”)

followed by a pause of 1.5 s,
– 1 short blink 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 TV is NOT in service mode.

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 TV in a
predefined way.

• The Service Alignment Mode (SAM). In this mode, items
of the TV can be adjusted via a menu.

You can activate both SDM and SAM modes via the “service
pads” on the SSB (see figure “Service pads”), via an RC­transmitter (DST or standard RC), or via ComPair. It is not
possible to activate the SAM in “stand-by”; the TV has to be in
“normal operation” mode.

The “Protection Diagram” shows the structure of the protection
system. See diagram below.

5.6.2 How To Activate

Use one of the following methods:

• Activate the SDM (only via soldering pads marked “SDM”
on SSB, see figure “Service pads”). 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.

5.7 Protections

5.7.1 Introduction

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 TV is put in protection mode. The

Figure 5-6 Protection diagram

There are several types of protections:

2

•I

C related protections.

• OTC related protections (via polling on I/O pins or via
algorithms).

• Hardware protection

All protections are explained below.

5.7.2 I

C Related Protections

In normal operation, some registers of the I
are refreshed every 200 ms. During this sequence, the I

short-circuited to ground, or to each other. An I
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 TV 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 TV in the protection mode. Before
the scanning is started, a so-called “ESD refresh” is carried out.

C controlled ICs

C

EN 20 FTL2.4A AA5.

Service Modes, Error Codes, And Fault Finding

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 TV.

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 TV is put in the protection mode.

Audio Supply 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 TV 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 Audio Supply
protection above), this is useful if there is something wrong in
the detection circuit of the DC/DC converter.

Audio DC Protection: This protection occurs when there is a
DC voltage on the speakers. In that case, the Main Supply is
switched “off”. The Stand-by Supply is still working.

Repair tip: If there is an audio DC protection (DC voltage on
your speakers), you will probably see error 18 blink. To be sure
this is an audio DC protection, disconnect the cable between
the SSB and the audio PWB and also the cable between the
Main Supply and the Audio PWB. If the TV starts up, it is very
likely that there is DC on the speakers. Check, and replace if
necessary, the audio amplifiers.
Note: 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 can not disappear through the
speakers).

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 TV. 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.

5.8.2 Protections

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

2

C “not-acknowledging” info of FBX + EPLD + 3D
Comb and of the tuner are overruled.
Caution: When doing this, the service technician must know
what he is doing, as it could lead to damaging the TV.

Note: It can sometimes take up to half a minute before the TV
goes to protection!

5.8 Repair Tips

5.8.1 3V3 Supply (DC/DC converter on the SSB)

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 TV goes to protection (I
is logged.
For further diagnoses, you need to overrule the I
put the TV in Service Default Mode by means of the solder
pads on the SSB (see figure “Service pads”).
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. Be aware 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 TV would start up and
you have normal picture, there is probably no overload but
a problem in the detection circuits.

You have no picture, so:

- Read the error buffer via ComPair (error buffer is accessible when set is in
protection, ComPair-file will guide you to this).

- Read the blinking LED information via standard remote command
<mute>06250x<ok>.

- Or you read the error code sequence via standard remote command

When you have found the error, check the circuitry related to the supply voltage

5.9 Software Downloading

In this chassis, you can upgrade the main software via
ComPair without removing the back cover of the TV (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, 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
number.
