Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

Index of this chapter:

2.1 Safety Instructions

2.2 Warnings

2.3 Notes

2.1 Safety Instructions

Safety regulations require that during a repair:

• Connect the set to the mains 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 lead for external
damage.

• Check the strain relief of the mains cord for proper function.

• Check the electrical DC resistance between the mains plug
and the secondary side (only for sets which have a mains
isolated power supply):

1. Unplug the mains cord and connect a wire between the

two pins of the mains plug.

2. Set the mains switch to the "on" position (keep the

mains cord unplugged!).

3. Measure the resistance value between the pins of the

mains 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 plug.

• Check the cabinet for defects, to avoid touching of any
inner parts by the customer.

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 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.

• Manufactured under license from Dolby Laboratories.
“Dolby”, “Pro Logic” and the “double-D symbol”, are
trademarks of Dolby Laboratories.

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 Electrical
Replacement 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.

Device Removal

As is the case with any component that, it is essential when
removing an (LF)BGA, 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 chance 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 shown to result in
problems during re-soldering.

),

).

Directions for Use

EN 5LC4.5E AA 3.

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.

to deal with BGA-ICs.

2.3.4 Lead Free Solder

Philips CE is going to produce lead-free sets (PBF) from

1.1.2005 onwards.

This sign normally has a diameter of 6 mm, but if there is less
space on a board also 3 mm is possible.

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 not to avoid, clean carefully 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
short before it is used (soldered). Otherwise the body of the
IC gets "wet" inside and during the heating time the
structure of the IC will be destroyed due to high (steam­)pressure inside the body. If the packaging was opened
before usage, the IC has to be heated up for some hours
(around 90°C) for drying (think of ESD-protection!).
Do not re-use BGAs at all!

• For sets produced before 1.1.2005, containing leaded
soldering tin and components, all needed spare parts will
be available till the end of the service period. For the repair
of such sets nothing changes.

In case of doubt whether the board is lead-free or not (or with
mixed technologies), you can use the following method:

• Always use the highest temperature to solder, when using
SAC305 (see also instructions below).

• De-solder thoroughly (clean solder joints to avoid mix of
two alloys).

Regardless of this logo (is not always present), one must treat
all sets from this date onwards according to the following rules.

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 at least a solder-tip temperature of 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 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 rise drastically and flux-fluid will be destroyed. To

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 - 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 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 foil is
not damaged and that it makes good electrical contact with
the metal frame. Be careful with the fragile LVDS cable.

1. Cautiously pull back the upper left part of the anti-static
copper foil (see Photo A). Do this in such a way that the foil
is no longer attached to the metal ground plate on which
the TV & Scaler board is mounted.

2. Disconnect the cables (2) of the “L” and the “R”
loudspeakers (see Photo A).

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

5.1 Test Points

This chassis is equipped with test points in the service printing.
In the schematics test points are identified with a rectangle box
around Fxxx or Ixxx. These test points are specifically
mentioned in the service manual as “half moons” with a dot in
the centre.
Perform measurements under the following conditions:

• Television set in Service Default Alignment 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 abilities of structured troubleshooting, error code
reading, and software version read-out for all chassis.
Minimum requirements for ComPair: a Pentium processor, a
Windows OS, and a CD-ROM drive (see also paragraph
"ComPair").

– Auto Volume Levelling (AVL).

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 (do not allow the OSD display to time out between
entries while keying the sequence).

• Short SDM jumper (item 4022, see Figure "Service
jumper") on the bottom side (solder side) of the TV &
Scaler board and apply AC Power. Remove the jumper
after start-up.
Caution: Entering SDM by shorting "Service" jumpers will
override the software protections. Do this only for a short
period. When doing this, the service-technician must

know exactly what he is doing, as it could damage the
television set.

5.4 ComPair

5.4.2 Specifications

ComPair consists of a Windows based fault finding program
and an interface box between a PC and the (defective) product.
The ComPair interface box is connected to the PC via a serial
(or RS232) 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/from 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 extent.
When this is not the case, ComPair will guide you through
the fault finding tree by asking you questions (e.g. Does the

screen give a picture? Click on the correct answer: YES /
NO) and showing you examples (e.g. Measure test-point I7
and click on the correct oscillogram you see on the
oscilloscope). You can answer by clicking on a link (e.g.

text or a waveform picture) that will bring you to the next
step in the fault finding process.

By a combination of automatic diagnostics and an interactive
question / answer procedure, ComPair will enable you to find
most problems in a fast and effective way.

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 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.

5.5 Error Codes

The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from the left to
the right. When an error occurs that is not yet in the error code
buffer, it is displayed on 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 OSD
display to time out between entries while keying the
sequence).

– Make sure the menu item CLEAR is highlighted. Use

the CURSOR UP/DOWN buttons, if necessary.

– Press the CURSOR RIGHT button to clear the error

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

• If an error does not re-occur within 50 hours it is deleted
from the error buffer.

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 indicate (by
blinking) 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 at 12 short blinks.

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).

EN 16 LC4.5E AA5.

Service Modes, Error Codes, and Fault Finding

5.7 Fault Finding and Repair Tips

Notes:

• It is assumed that the components are mounted correctly,
with correct values and with 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.

Table 5-3 NVM editor overview

Hex Dec Description

.ADR 0x000A 10 Existing value
.VAL 0x0000 0 New value
.Store Store?

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.
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 via the AC Power switch.

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

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

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

5. When the set has started, the P+/Ch+ button can be
released and the short circuit of the SDM jumpers can be
removed.

6. The red LED will be on continuously to indicate that the
download is initiated (normally when SDM is activated the
red LED will start with the Blinking LED sequence).

7. Wait +/- 30 s (time needed to download default values to
the NVM).

No Picture Display

1. Check the RGB signal.

2. If it is present, check 3-IC7016 (NE555).

3. If it has output, the problem is in SCALER part.

4. Otherwise, check H-out on pin 2 of NE555. If the input
signal of pin 2 is present, but no output, the IC is defect.

Note:

• If the H-out (pin 67) doesn’t have signal or the level is low,
check the output of NE555 (pin 3) during start up.

• If the H-out (pin 67) has a signal (or has a signal for a very
short time), change IC7016 (NE555).

No TV but PC is Present

1. Check if HSYNC and VSYNC are present at pin 3 of 7017
and 7015.

2. If they are present, check RGB output.

3. If there is no RGB output, the IC TDA120xx can be defect.

5.7.5 Power Supply

This power supply contains two fuses. One is near the AC
Power (or mains) inlet connector 1308 and the other is near
connector 1307.

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

2. Fuse 1400 may open in case of severe lightning strikes
and/or failures in the power supply.

3. Fuses 1401 may open in case of a problem with the Stand­by Supply. Replacement of the fuse is needed, but not
