Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

EN 5LC4.3U 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.

2.3 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
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.

-9

), or pico-farads (p= x10

-12

-6

),

).

2.2 Warnings

• 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.

2.3.3 Rework on BGA (Ball Grid Array) ICs

General

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

Device Removal

As is the case with any component that, is being removed, it is
essential when removing an (LF)BGA, that the board, tracks,
solder lands, or surrounding components are not damaged. To
remove an (LF)BGA, the board must be uniformly heated to a
temperature close to the reflow soldering temperature.
A uniform temperature reduces the risk of warping the PWB. To
do this, we recommend that the board is heated until it is certain
that all the joints are molten. Then carefully pull the component
off the board with a vacuum nozzle. For the appropriate
temperature profiles, see the IC data sheet.

Area Preparation

When the component has been removed, the vacant IC area
must be cleaned before replacing the (LF)BGA.
Removing an IC often leaves varying amounts of solder on the
mounting lands. This excessive solder can be removed with
either a solder sucker or solder wick. The remaining flux can be
removed with a brush and cleaning agent.

EN 6 LC4.3U AA2.

Safety Instructions, Warnings, and Notes

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
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.

More Information

then go to “Workshop Information”. Here you will find
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 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.

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).

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.

• 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.

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.

2.3.5 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.

The foam bars (order code 3122 785 90580) can be used for
all types and sizes of Flat TVs. By laying the plasma or LCD TV
flat on the (ESD protective) foam bars, a stable situation is
created to perform measurements and alignments. By first
placing a mirror flat on the table under the TV you can easily
see if something is happening on the screen.

To remove the LCD-panel, carry out the following steps:

1. Cautiously pull back the upper parts of the anti-static
copper foils next to the “L” and “R” loudspeakers (see
Figure “Anti-static copper foil”). Do this in such a way that
the foils are no longer attached to the metal ground plate
on which the SSB board is mounted.

2. Disconnect the cables (2) from the “L” and the “R”
loudspeakers (see Figure “Anti-static copper foil”).

3. Important: Unplug the LVDS connector (3) on the LCD
panel (see Figure “LVDS connector”).
Be careful, as this is a very fragile connector!

4. Unplug the connectors (4) of the Side I/O panel, the Top
Control panel, and the LED panel on the SSB board (see
Figure “SSB board connectors for side I/O, keyboard
control, and LED”).

5. Unplug the X520 and X530 connectors (5) on the Power
Supply board (see Figure “ Connectors X520 and X530 on
power supply panel”). Instead of X520, also connector 66B
(6) on the other end of the flatcable can be unplugged (see
Figure “Connector 66B on LCD panel”).

6. Lift the metal frame (together with all PWBs) from the LCD
panel.

Take care not to damage the fragile LVDS cable, the
66B connector and the anti-static copper foils near the
“L” and “R” loudspeakers (take care of this too when
later re-assembling the TV set and replacing the
copper foil).

7. After removal of the metal frame, you can lift the LCD
display (7) from its plastic frame (see Figure “LCD panel”).

8. If the plastic frame is damaged, replace it by a new frame,
after removing the loudspeakers, the Side I/O panel, the
Top Control panel, and the LED panel.

4.4 Set Re-assembly

To re-assemble the whole set, execute all processes in reverse
order.

Notes:

• While re-assembling, make sure that all cables are placed
and connected in their original positions. See Figure "Cable
dressing". Also make sure that the anti-static copper foils
are not damaged and that they make good electrical
contact with the metal frame. Be careful with the fragile
LVDS cable.

around Fxxx or Ixxx.
Perform measurements under the following conditions:

• Television set in Service Default Mode.

• Video input: Colour bar signal.

• Audio input: 3 kHz left channel, 1 kHz right channel.

5.2 Service Modes

Service Default mode (SDM) and Service Alignment Mode
(SAM) offers several features for the service technician, while
the Customer Service Mode (CSM) is used for communication
between the call centre and the customer.

This chassis also offers the option of using ComPair, a
hardware interface between a computer and the TV chassis. It
offers the possibilities of structured troubleshooting, error code
reading, and software version readout for all chassis.
Minimum requirements for ComPair: a Pentium processor, a
Windows OS, and a CD-ROM drive (see also paragraph
"ComPair").

How to Enter

To enter SDM, use one of the following methods:

• Press the following key sequence on the remote control
transmitter: “062596” directly followed by the MENU button

5.4 ComPair

• 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.

5.4.2 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:

• Automatic (by communication with the television): ComPair
can automatically read out the contents of the entire error
buffer. Diagnosis is done on I
access the I
send and receive I

2

C/UART bus of the television. ComPair can

C/UART commands to the micro

2

C/UART level. ComPair can

controller of the television. In this way, it is possible for
ComPair to communicate (read and write) to devices on

2

the I

C/UART 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 extend.
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 (European) Dealer Service Tool (DST).

• If both ComPair and Force/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.

5.4.1 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:

• 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 UART interface cable: 3122 785 90630

Note: If you encounter any problems, contact your local
support desk.

5.5 Error Codes

The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, it is displayed at the left side and all other errors shift one
position to the right.

5.5.1 How to Read the Error Buffer

You can read the error buffer in 3 ways:

• On screen via the SAM (if you have a picture).

Examples:

– ERROR: 0 0 0 0 0 : No errors detected
– ERROR: 6 0 0 0 0 : Error code 6 is the last and only

detected error

– ERROR: 9 6 0 0 0 : Error code 6 was detected first and

error code 9 is the last detected (newest) error

• Via the blinking LED procedure (when you have no
picture). See “The Blinking LED Procedure”.

•Via ComPair.

5.5.2 How to Clear the Error Buffer

The error code buffer is cleared in the following cases:

• By using the CLEAR command in the SAM menu:
– To enter SAM, press the following key sequence on the

remote control transmitter: “062596” directly followed
by the OSD/STATUS button (do not allow the display
to time out between entries while keying the
sequence).

– Make sure the menu item CLEAR is highlighted. Use

the MENU UP/DOWN buttons, if necessary.

– Press the MENU RIGHT button to clear the error

buffer. The text on the right side of the “CLEAR” line will
change from “CLEAR?” to “CLEARED”

• If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.

Note: If you exit SAM by disconnecting the mains from the
television set, the error buffer is not reset.

5.5.3 Error Codes

In case of non-intermittent faults, write down the errors present
in the error buffer and clear the error buffer before you begin
the repair. This ensures 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
and not the actual cause of the problem (for example, a fault in
the protection detection circuitry can also lead to a protection).

Service Modes, Error Codes, and Fault Finding

5.6 The Blinking LED Procedure

Using this procedure, you can make the contents of the error
buffer visible via the front LED. This is especially useful when
there is no picture.

When the SDM is entered, the front LED will blink the contents
of the error-buffer:

• The LED blinks with as many pulses as the error code
number, followed by a time period of 1.5 seconds, in which
the LED is off.

• Then this sequence is repeated.

Any RC5 command terminates this sequence.

Example of error buffer: 12 9 6 0 0
After entering SDM, the following occurs:

• 1 long blink of 5 seconds to start the sequence,

• 12 short blinks followed by a pause of 1.5 seconds,

• 9 short blinks followed by a pause of 1.5 seconds,

• 6 short blinks followed by a pause of 1.5 seconds,

• 1 long blink of 1.5 seconds to finish the sequence,

• The sequence starts again with 12 short blinks.

5.7 Fault Finding and Repair Tips

EN 19LC4.3U AA 5.

Notes:

• It is assumed that the components are mounted correctly
with correct values and no bad solder joints.

• Before any fault finding actions, check if the correct options
are set.

5.7.1 NVM Editor

In some cases, it can be handy if one directly can change the
NVM contents. This can be done with the “NVM Editor” in SAM
mode. With this option, single bytes can be changed.

Caution:

• Do not change the NVM settings without
understanding the function of each setting, because
incorrect NVM settings may seriously hamper the
correct functioning of the TV set!

• Do not change the Scaler NVM settings, as this will
hamper the DVI functionality of the TV set!

• Always note down the existing NVM settings, before
changing the settings. This will enable you to return to the
orgininal settings, if the new settings turn out to be
incorrect.

5.7.2 Load Default NVM Values

In case a blank NVM is placed or when the NVM content is
corrupted, default values can be downloaded into the NVM.
(For empty NVM replacement, short the SDM with a jumper
and apply the mains voltage. Remember to remove the jumper
after the reload is completed). After the default values are
downloaded, it will be possible to start up and to start aligning
the TV set. This is no longer initiated automatically; to initiate
the download the following action has to be performed:

1. Switch “off” the TV set by disconnecting the AC Power

2. Short circuit the SDM jumpers (keep short-circuited).

3. Press P+ or Ch+ on the local keyboard (and keep it

4. Switch on the TV set via the AC Power plug.

5. Keep pressing the P+/Ch+ button until the set has started

Alternative method:

1. Go to SAM.

2. Select NVM Editor (not SC NVM Editor).

3. Select ADR (address) to 1 (dec).

4. Change the VAL (value) to 170 (dec).

5. Store the value.

6. Disconnect the mains plug and wait for a few seconds.

7. Reconnect the mains plug and wait until the set goes into

8. Restart the set.

up and the SDM is shown.

its standby mode (red LED lights up).

5.7.3 Tuner and IF

No Picture in RF Mode, but there is a Noise Raster

1. Check whether picture is present in AV. If not, go to Video
processing troubleshooting section.

2. If present, check if the Option settings are correct.

3. Check if all the supply voltages are present (3.3/5/8/12/33
V).

4. Check if the I

5. Manually store a known channel and check if there is IF
output at Tuner pin 11.

6. Check the tuning DC voltage at pin 2 of the Tuner. The DC
voltage should vary according to the frequency/channel
being chosen.

7. If the tuning voltage is OK, check the tuner output, pin 11.

8. If it has no output, the Tuner may have a defect. Change
the Tuner.

Sound in Picture Problem for L' System (rolling horizontal lines)

1. Check whether AGC L' in SAM mode is set to 0.

2. If yes, align the set to correct value.

Required System is not Selected Correctly

Check whether a Service jumper (#4204 & 4205, 0805 size) is
present. If yes, remove it.

C lines are working correctly (3.3 V).

EN 22 LC4.3U AA5.

Service Modes, Error Codes, and Fault Finding

5.7.4 Video Processing

No Power

1. Check +12 V and 3V3 at position 1J02.

2. If no supply, check the connector 1J02.

3. If it is correct, check the power supply board.

Power Supply is Correct, but no Green LED

1. Check if the connectors 1K00 are properly inserted.

2. If they are inserted correctly, check if the 3V3 is present.

No Picture Display (blank screen with correct sound output)

1. Check whether the user menu is visible.

2. If the user menu is OK, activate teletext mode.

3. If teletext is OK, the problem is in the ADC (B18) &
Columbus 3D combfilter (B19), if present (depending on
model, see also paragraph “Teletext Path” in chapter 9).

4. If the user menu is not visible, check if the LCD panel
backlight is ON.

5. If the backlight is OFF, the problem is in the power supply
board or LCD panel. Also check pin 12 (LAMP_ON_OFF)
of 1J02. It should be HIGH during normal operation.

Note: For faultfinding purposes, it is important to know the
following: in Pixel Plus and Digital Crystal Clear models, which
have an ADC (B18) and Columbus 3D combfilter (B19), the
digital input of the scaler is used for the digital video path
(Hercules output), whereas the analogue RGB input (analogue
input of the scaler) is only used for teletext. This means that no
mixed mode (video plus teletext simultaneously) is possible. If
there is sound and teletext, but no video and user menu (blank
screen), the digital path (Hercules - ADC - Columbus - Scaler)
is faulty. If there is sound but no teletext, the back-end part
(Scaler - LCD panel) is faulty. In Crystal Clear models, which
do not have an ADC and Columbus, the RGB path (analogue
input of scaler) is used for both video and teletext.

4. 24 V output (for inverter X520 & X530): Short-circuit
proof with auto-restart. Over voltage protection when
output voltage is more than 40% above nominal value.

Standby Mode

1. Apply a 12 ohm load resistor of sufficient power rating to all
outputs mentioned above (+12 V, +18/ 24 V, +3V3 and +24
V). Connect the STBY pin (pin 10 of X200) to logical “L”
(low), i.e. to GND.

2. Over an input voltage range of 90 V

to 276 VAC only the

AC

+3V3 STBY output shall be up.

Normal Mode:

1. Apply a 12 ohm load resistor of sufficient power rating to all
outputs mentioned above (+12 V, +18/ 24 V, +3V3 and +24
V). Connect the STBY pin (pin 10 of X200) to logical “H”
(high), i.e. to the +3V3 STBY output via a 2,2 k pull up
resistor.

2. Over an input voltage range of 90 V

to 276 VAC all

AC

outputs shall be up. The voltage on the +3V3 STBY output
shall be 3.3 V over the entire input voltage range. The
voltage on the big 400 V capacitor on the power supply
should also be 400 V ±10%.

No TV, but PC is Present

1. Check if Hsync_SDTV and Vsync_SDTV are present at pin
1 & pin13 of 7E03.

2. If they are present, check teletext output.

3. If there is no teletext output, the IC TDA150xx may be
defect.

5.7.5 Power Supply

Check Fuse

The power supply (various models are used) contains one fuse
near the AC input connector X002.

1. Check with power supply in “off” state by means of ohmic
measurement.

2. Fuse X102 may open in case of severe lightning strikes
and/or failures in the power supply.

3. Check the standby signal at pin 10 of X200. ON is HIGH,
OFF is LOW. During standby mode only the 3V3 is present
at pin 10.

Protections Concept on Power Supply Board (two models)

1. 12 V output (pin 8 of X200): Short-circuit protected by 2.5
A fuse X610. Over-voltage protection when output voltage
is more than 40% above nominal value.

2. Vaudio output (+18 or +24 V, depending on power
supply model used); (pin 1 of X200): Short-circuit proof
(+18 V version has 2.5 A fuse X660). Over voltage
protection when output voltage is more than 40% above
nominal value.

3. 3V3STBY output (pin 3&4 of X200): Short-circuit proof
with auto-restart. Over voltage protection when output
voltage is more than 40% above nominal value.
