Safety Instructions, Warnings, and Notes

EN 4 LC4.6L AA2.

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 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 AC Power lead for external

damage.

• Check the strain relief of the AC Power cord for proper

function.

• Check the electrical DC resistance between the AC Power

plug and the secondary side (only for sets which have a AC

Power isolated power supply):

1. Unplug the AC Power cord and connect a wire

between the two pins of the AC Power plug.

2. Set the AC Power switch to the "on" position (keep the

AC Power cord unplugged!).

3. Measure the resistance value between the pins of the

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 AC Power 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” 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

-6

),

nano-farads (n= x10

-9

), or pico-farads (p= x10

-12

).

• 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.

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 5LC4.6L 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.

Information on how 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.

Figure 2-1 Lead-free logo

This sign normally has a diameter of 6 mm, but if there is less

space on a board also 3 mm is possible.

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

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).

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 - 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.

4.2 Service Positions

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).

4.2.1 Foam Bars

Figure 4-2 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.

4.2.2 Aluminium Stands

Figure 4-3 Aluminium stands (drawing of MkI)

The aluminium stands (order code 3122 785 90480) can be

mounted with the back cover removed or still left on. So, the

stand can be used to store products or to do measurements. It

is also very suitable to perform duration tests without taking

much space, without having the risk of overheating, or the risk

of products falling. The stands can be mounted and removed

quick and easy with use of the delivered screws that can be

tightened and loosened manually without the use of tools. See

figure above.

Note: Only use the delivered screws to mount the monitor to

the stands.

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

5.4 ComPair

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

2

C level) and

is therefore capable of accurately indicating problem areas.

You do not have to know anything about I

2

C commands

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.

5.4.2 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

2

C/UART level. ComPair can

access the I

2

C/UART bus of the television. ComPair can

send and receive I

2

C/UART 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/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.

Service Modes, Error Codes, and Fault Finding

EN 12 LC4.6L AA5.

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 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.

5.5.3 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).

Table 5-2 Error code overview

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 at 12 short blinks.

5.7 Fault Finding and Repair Tips

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.

Table 5-3 NVM editor overview

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).

5.7.3 Tuner and IF

No Picture in RF mode

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

processing troubleshooting section.

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

3. Check that all supply voltages are present.

4. Check if I

2

C lines are working correctly (3.3V).

5. Manually store a known channel and check if there is IF

output at Tuner pin 11.

6. Feed in 105 dBuV at Tuner pin 11 and check whether there

is RGB output from Video Processing IC. If yes, Tuner may

be defect. Replace Tuner.

Required system is not selected correctly

1. Check whether a Service jumper (#4022, 0805 size) is

present. If yes, remove it.

5.7.4 Video Processing

No power

1. Check +12 V and 3V3 at position 1910.

2. If no supply, check the connector 1910.

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

Power supply is correct but no green LED

1. Check if connectors 1005 and 1601 are properly inserted.

2. If yes, check if the 3V3 is present.

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 pin2 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 (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 Stand-

by Supply. Replacement of the fuse is needed, but not

before the cause of the overload conditions is resolved.
