Safety Instructions, Warnings, and NotesEN 4 LC4.5E AA2.

2. Safety Instructions, Warnings, and Notes Index of this chapter:2.1 Safety Instructions2.2 Warnings2.3 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 ,

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 ). 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 (), or hot ground (), 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 () and without () aerial signal. Measure the voltages in the power supply section both in normal operation () and in stand-by (). 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 (= 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 Electrical Replacement Parts List. Therefore, always check this list when there is any doubt.

2.3.3 Rework on BGA (Ball Grid Array) ICs

GeneralAlthough (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 RemovalAs 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 PreparationWhen 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 ReplacementThe 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 InformationFor more information on how to handle BGA devices, visit this URL: http://www.atyourservice.ce.philips.com (needs subscription). After login, select Magazine, 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 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 400C. 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 360C - 380C is reached and stabilised at the solder joint. Heating time of the solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400C, 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 90C) 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.

Figure 4-2 Foam bars

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.

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").

5.2.1 Service Default Mode (SDM)

Purpose To create a predefined setting for measurements. To override software protections. To start the blinking LED procedure. To inspect the error buffer. To check the life timer.

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 I2C level) and is therefore capable of accurately indicating problem areas. You do not have to know anything about I2C 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 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 I2C/UART level. ComPair can access the I2C/UART bus of the television. ComPair can send and receive I2C/UART commands to/from the micro controller of the television. In this way, it is possible for ComPair to communicate (read and write) to devices on the I2C/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.

5.4.3 How to Connect

This is described in the chassis fault finding database in ComPair.

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 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.

5.5.3 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 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 0After 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 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

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 Mode1. 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 I2C 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 Correctly1. Check whether a Service jumper (#4022, 0805 size) is

present. If yes, remove it.

5.7.4 Video Processing

No Power1. 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 LED1. Check if connectors 1005 and 1601 are properly inserted.2. If yes, check if the 3V3 is present.

No Picture Display1. 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) doesnt 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 Present1. 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 Stand-by Supply. Replacement of the fuse is needed, but not before the cause of the overload conditions has been resolved.
