Safety Instructions, Warnings, and NotesEN 4 L04L AB2.

2. Safety Instructions, Warnings, and Notes Index of this chapter:2.1 Safety Instructions2.2 Maintenance Instructions2.3 Warnings2.4 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 ,

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.

Wear safety goggles when you replace the CRT.

Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the following points: General repair instruction: as a strict precaution, we advise

you to re-solder the solder connections through which the horizontal deflection current flows. In particular this is valid for the:1. Pins of the line output transformer (LOT).2. Fly-back capacitor(s).3. S-correction capacitor(s).4. Line output transistor.5. Pins of the connector with wires to the deflection coil.6. Other components through which the deflection current

flows.

Note: This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections, and is therefore only necessary for television sets more than two years old. Route the wire trees and EHT cable correctly and secure

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, to prevent the cord from touching the CRT, hot components, or heat sinks.

Check the electrical DC resistance between the Mains/AC Power plug and the secondary side (only for sets that have a Mains/AC Power isolated power supply): 1. Unplug the Mains/AC Power cord and connect a wire

between the two pins of the Mains/AC Power plug. 2. Set the Mains/AC Power switch to the "on" position

(keep the Mains/AC Power cord unplugged!). 3. Measure the resistance value between the pins of the

Mains/AC Power plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be between 4.5 Mohm and 12 Mohm.

4. Switch "off" the set, and remove the wire between the two pins of the Mains/AC Power plug.

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

2.2 Maintenance Instructions

We recommend a maintenance inspection carried out by qualified service personnel. The interval depends on the usage conditions: When a customer uses the set under normal

circumstances, for example in a living room, the recommended interval is three to five years.

When a customer uses the set in an environment with higher dust, grease, or moisture levels, for example in a kitchen, the recommended interval is one year.

The maintenance inspection includes the following actions:

1. Perform the general repair instruction noted above.2. Clean the power supply and deflection circuitry on the

chassis.3. Clean the picture tube panel and the neck of the picture

tube.

2.3 Warnings

In order to prevent damage to ICs and transistors, avoid all high voltage flashovers. In order to prevent damage to the picture tube, use the method shown in figure Discharge picture tube, to discharge the picture tube. Use a high voltage probe and a multi-meter (position VDC). Discharge until the meter reading is 0 V (after approx. 30 s).

Figure 2-1 Discharge picture tube

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 prevents circuits from becoming unstable.

2.4 Notes

2.4.1 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.

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

2.4.2 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 Spare Parts List. Therefore, always check this list when there is any doubt.

2.4.3 BGA (Ball Grid Array) ICs

IntroductionFor more information on how to handle BGA devices, visit this URL: www.atyourservice.ce.philips.com (needs subscription, not available for all regions). After login, select Magazine, then go to Repair downloads. Here you will find Information on how to deal with BGA-ICs.

BGA Temperature ProfilesFor 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 "Repair downloads".For additional questions please contact your local repair help desk.

2.4.4 Lead-free Soldering

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 400C. To stabilize the adjusted temperature at the solder-tip. To exchange solder-tips for different applications.

Adjust your solder tool so that a temperature of around 360C - 380C is reached and stabilized 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 increase drastically and flux-fluid will be destroyed. To avoid wear-out of tips, switch off unused equipment or reduce heat.

Mix of lead-free soldering tin/parts with leaded soldering tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin.

2.4.5 Alternative BOM identification

The third digit in the serial number (example: AG2B0335000001) indicates the number of the alternative B.O.M. (Bill Of Materials) that has been used for producing the specific TV set. In general, it is possible that the same TV model on the market is produced with e.g. two different types of displays, coming from two different suppliers. This will then result in sets which have the same CTN (Commercial Type Number; e.g. 28PW9515/12) but which have a different B.O.M. number.By looking at the third digit of the serial number, one can identify which B.O.M. is used for the TV set he is working with.If the third digit of the serial number contains the number 1 (example: AG1B033500001), then the TV set has been manufactured according to B.O.M. number 1. If the third digit is a 2 (example: AG2B0335000001), then the set has been produced according to B.O.M. no. 2. This is important for ordering the correct spare parts!For the third digit, the numbers 1...9 and the characters A...Z can be used, so in total: 9 plus 26= 35 different B.O.M.s can be indicated by the third digit of the serial number.

Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 1 and 2 refer to the production center (e.g. AG is Bruges), digit 3 refers to the B.O.M. code, digit 4 refers to the Service version change code, digits 5 and 6 refer to the production year, and digits 7 and 8 refer to production week (in example below it is 2006 week 17). The 6 last digits contain the serial number.

Figure 2-2 Serial number (example)

2.4.6 Board Level Repair (BLR) or Component Level Repair (CLR)

If a board is defective, consult your repair procedure to decide if the board has to be exchanged or if it should be repaired on component level.If your repair procedure says the board should be exchanged completely, do not solder on the defective board. Otherwise, it cannot be returned to the O.E.M. supplier for back charging!

2.4.7 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.

5.2.3 Customer Service Mode (CSM)

PurposeThe Customer Service Mode shows error codes and information on the TVs operation settings. The call center can instruct the customer (by telephone) to enter CSM in order to identify the status of the set. This helps the call center to diagnose problems and failures in the TV set before making a service call.The CSM is a read-only mode; therefore, modifications are not possible in this mode.

How to enterTo enter CSM, press the following key sequence on the remote control transmitter: 123654 (do not allow the display to time out between entries while keying the sequence).

Upon entering the Customer Service Mode, the following screen will appear:

5.4 Service Tools

5.4.1 ComPair

IntroductionComPair (Computer Aided Repair) is a Service tool for Philips Consumer Electronics products. and offers the following:1. ComPair helps you to quickly get an understanding on how

to repair the chassis in a short and effective way.2. ComPair allows very detailed diagnostics and is therefore

capable of accurately indicating problem areas. You do not have to know anything about I2C or UART commands yourself, because ComPair takes care of this.

3. ComPair speeds up the repair time since it can automatically communicate with the chassis (when the uP is working) and all repair information is directly available.

4. ComPair features TV software upgrade possibilities.

SpecificationsComPair consists of a Windows based fault finding program and an interface box between PC and the (defective) product. The (new) ComPair II interface box is connected to the PC via an USB cable. For the TV chassis, the ComPair interface box and the TV communicate via a bi-directional cable via the service connector(s).The ComPair fault finding program is able to determine the problem of the defective television, by a combination of automatic diagnostics and an interactive question/answer procedure.

How to ConnectThis is described in the chassis fault finding database in ComPair.

Figure 5-4 ComPair II interface connection

Caution: It is compulsory to connect the TV to the PC as shown in the picture above (with the ComPair interface in between), as the ComPair interface acts as a level shifter. If one connects the TV directly to the PC (via UART), ICs will be blown!

How to OrderComPair II order codes: ComPair II interface: 3122 785 91020. ComPair32 CD (update): 3122 785 60160. ComPair interface cable: 3122 785 90004. ComPair interface extension cable: 3139 131 03791. ComPair UART interface cable: 3122 785 90630.

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 AC power 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).

Table 5-3 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: When all the error-codes are displayed, the sequence

finishes with a LED blink of 1.5 seconds, The sequence starts again.

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 Protections

If a fault situation is detected, an error code will be generated; and, if necessary, the television set will go into protection mode. Blinking of the red LED at a frequency of 3 Hz indicates the protection mode. In some error cases, the microprocessor does not put the set in protection mode. The error codes of the error buffer and the blinking LED procedure can be read via the Service Default Menu (SDM), or via ComPair.

To get a quick diagnosis the chassis has three service modes implemented: The Customer Service Mode (CSM). The Service Default Mode (SDM). The Service Alignment Mode (SAM).

For a detailed mode description, see the relevant sections.

5.8.6 Controller

Below are some guidelines for troubleshooting of the Micro Controller function. Normally Micro Controller should be checked when there is a problem of startup.1. Check that both +3.3 V_dc and +1.8 V_dc are present.2. Check that crystal oscillator is working.3. Check that Power Good signal is at high logic, normal

operation.4. Check that HERCULES is not in standby mode. Pin 15 of

HERCULES should be 0 V_dc.5. Make sure H-drive pulse is there. This can be checked at

resistor R3239. If H-drive does not exist, remove resistor R3239 to check if there is loading.

Note: When the set shuts down after a few second after power on, the main cause is that Vg2 not aligned properly, try adjusting Vg2 during the few seconds of power on.

5.8.7 Video Processing

No PictureWhen no picture in RF, first check if the microprocessor is functioning ok in section Controller. If that is ok, follow the next steps. When no picture in AV, first check if the video source selection is functioning ok in section Source Selection. If that is ok, follow the next steps.

1. Check that normal operating conditions are met.2. Check that there is video signal at pin 81. If no video,

demodulator part of the HERCULES is faulty, replace with new HERCULES.

3. If video signal is available at pin 81, check pin 56, 57, and 58 for the RGB signal.

4. If signal is not available, try checking the BRIGHTNESS and/or CONTRAST control, and make sure it is not at zero.

5. If still with the correct settings and no video is available, proceed to the CRT/RGB amplifier diagram.

For sets with TDA9178, follow steps below:1. Put Option Byte 2 bit 4 to 0; if video signal is not available,

then check fault finding section Controller, Section Source Selection, and steps above.

2. If video is available but not correct, put Option Byte 2 bit 4 to 1, then check if LTI panel is present. If not, put LTI panel in the main chassis (connector 1221).

3. If LTI panel is in main chassis, check cable between LTI panel and main chassis (position is 1206). If it is connected, then the LTI panel is faulty, replace it.

For sets with Scavem, and Scavem does not work, follow steps below:1. Check Scavem coil connector (position is 1361) if

connected; if not, connect it.2. If connected, check NVM bit storage byte 1 bit 7; if it is not

1, set it to 1.3. If it is 1, then check the data of the NVM addresses as in

the next table. If the data is not correct, then set these addresses to diagram values.

4. If it still not works, track Scavem output from pin64 of HERCULES to CRT panel.
