2. Safety Instructions, Warnings, and Notes

Index of this chapter:2.1 Safety Instructions For Repairs2.2 Maintenance Instructions2.3 Warnings2.4 Notes

2.1 Safety Instructions For Repairs

Safety regulations require that during a repair:• Due to the ‘hot’ parts of this chassis, the set must be

connected to the AC power via an isolation transformer.• Safety components, indicated by the symbol �, should be

replaced by components identical to the original ones.• When replacing the CRT, safety goggles must be worn. Safety regulations require that after a repair, the set must be returned in its original condition. Pay 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 is flowing, in particular:– all pins of the line output transformer (LOT)– fly-back capacitor(s)– S-correction capacitor(s)– line output transistor– pins of the connector with wires to the deflection coil– 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 AC power cord for external

damage.• Check the strain relief of the 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 AC plug and the secondary side (only for sets that have an isolated power supply). Do this as follows:1. Unplug the AC power cord and connect a wire between

the two pins of the AC plug.2. Turn on the main power switch (keep the AC power

cord unplugged!).3. Measure the resistance value between the pins of the

AC plug and the metal shielding of the tuner or the aerial connection of the set. The reading should be between 4.5 MΩ and 12 MΩ.

4. Switch the TV OFF and remove the wire between the two pins of the AC plug.

• Check the cabinet for defects, to prevent the possibility of the customer touching any internal parts.

2.2 Maintenance Instructions

It is recommended to have a maintenance inspection carried out by qualified service personnel. The interval depends on the usage conditions:• When the set is used under normal circumstances, for

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

• When the set is used 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 Fig. 2-1, 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

• All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD)�. Careless handling during repair can reduce life drastically. When repairing, make sure that 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 potential. Available ESD protection equipment:– Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable, and ground cable) 4822 310 10671.

– Wristband tester 4822 344 13999.• Together with the deflection unit and any multi-pole unit,

flat square picture tubes form an integrated unit. The deflection and the multi-pole units are set optimally at the factory. Adjustment of this unit during repair is therefore not recommended.

• Be careful during measurements in the high voltage section and on the picture tube.

• 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.

2.4 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.

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 (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.

2.4.3 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.

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.To reflow the solder, apply a temperature profile according to the IC data sheet. So as not to damage neighbouring components, it may be necessary to reduce some temperatures and times.

2.4.4 Lead Free Solder

Philips CE is going to produce lead-free sets (PBF) from 1.1.2005 onwards.

Figure 2-2 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)

2.4.5 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.

5.2.3 Customer Service Mode (CSM)

PurposeWhen a customer is having problems with his TV-set, he can call his dealer. The service technician can than ask the customer to activate the CSM, in order to identify the status of the set. Now, the service technician can judge the severness of the complaint. In a lot of cases he can advise the customer how to solve the problem, or he can decide if it is necessary to visit the customer.The CSM is a read only mode, therefore modifications in this mode are not possible.

How to enterThe CSM will be turned on after pressing the MUTE key on the remote control transmitter and any of the control buttons on the TV for at least 4 seconds simultaneously. This activation only works if there is no menu on the screen. After switching ON the Customer Service Mode, the following screen will appear:

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 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 faultfinding program and an interface box between PC and the (defective) product. The ComPair interface box is connected to the PC via a serial or RS232 cable. In case of the L01 chassis, the ComPair interface box and the TV communicate via a bi-directional service cable via the service connector (located on the Main panel, see also figure 8-1 suffix D). The ComPair faultfinding 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 level. ComPair can access the I2C bus of the television. ComPair can send and

receive I2C 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 I2C busses 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 faultfinding tree by asking you questions (e.g. Does the screen gives 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 faultfinding 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 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 Monocarrier.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

1. First install the ComPair Browser software (see the Quick Reference Card for installation instructions).

2. Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ‘PC’) of the ComPair interface.

3. Connect the AC power adapter to the supply connector (marked with ‘POWER 9V DC’) on the ComPair interface.

4. Switch the ComPair interface OFF.5. Switch the television set OFF (remove the AC power).6. Connect the ComPair interface cable between the

connector on the rear side of the ComPair interface (marked with ‘I2C’) and the ComPair connector on the mono carrier (see figure 8-1 suffix D).

7. Plug the AC power adapter in the AC power outlet and switch on the interface. The green and red LEDs light up together. The red LED extinguishes after approx. 1 second while the green LED remains lit.

8. Start the ComPair program and read the ‘introduction’ chapter.

5.5 Error Buffer

The error code buffer contains all detected errors 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 written at the left side and all other errors shift one position to the right.

5.5.1 How to Read the Error Buffer

Use one of the following methods:• On screen via the SAM (only 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 first detected and error code 9 is the last detected (newest) error

• Via the blinking LED procedure (when you have no picture). See next paragraph.

• Via ComPair.

5.5.2 How to Clear the Error Buffer

The error code buffer is cleared in the following cases:• By activation of the CLEAR command in the SAM menu:• When you exit SDM / SAM with the STANDBY command

on the remote control (when leaving SDM / SAM, by disconnecting the set from AC power, the error buffer is not reset).

• When you transmit the command DIAGNOSE-99-OK with ComPair.

• If the content of the error buffer has not changed for 50 hours, it resets automatically.

5.5.3 Error Codes

In case of non-intermittent faults, clear the error buffer before you begin the repair. These to ensure 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 code and not the actual cause (e.g., a fault in the protection detection circuitry can also lead to a protection).

5.6 The Blinking LED Procedure

Via 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 LED will blink the contents of the error-buffer. Error-codes ≥ 10 are shown as follows:– a long blink of 750 ms (which is an indication of the decimal

digit),– a pause of 1.5 s,– n short blinks (n = 1 - 9),– when all the error-codes are displayed, the sequence

finishes with a LED blink of 3 s,– the sequence starts again. Example of error buffer: 12 9 6 0 0 After entering SDM: – 1 long blink of 750 ms followed by a pause of 1.5 s,– 2 short blinks followed by a pause of 3 s,– 9 short blinks followed by a pause of 3 s,– 6 short blinks followed by a pause of 3 s,– 1 long blink of 3 s to finish the sequence,– the sequence starts again.

5.7 Protections

If a fault situation is detected an error code will be generated and if necessary, the set will be put in the 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 the protection mode. The error codes of the error buffer can be read via the service menu (SAM), the blinking LED procedure or via ComPair. The DST diagnose functionality will force the set into the Service-standby, which is similar to the usual standby mode, however the microprocessor has to remain in normal operation completely. To get a quick diagnosis the chassis has three service modes implemented:• The Customer Service Mode (CSM).• The Service Default Mode (SDM). Start-up of the set in a

predefined way.• The Service Alignment Mode (SAM). Adjustment of the set

via a menu and with the help of test patterns. See for a detailed description Chapter 9 paragraphs Deflection and Power Supply.

5.8 Repair Tips

Below some failure symptoms are given, followed by a repair tip.• Set is dead and makes hiccuping sound ‘MainSupply’ is

available. Hiccuping stops when de-soldering L5561, meaning that problem is in the ‘MainSupply’ line. No output voltages at LOT, no horizontal deflection. Reason: line transistor TS7460 is defective.

• Set is dead, and makes no sound Check power supply IC7520. Result: voltage at pins 1, 3, 4, 5 and 6 are about 180 V and pin 8 is 0 V. The reason why the voltage on these pins is so high is because the output driver (pin 6) has an open load. That is why MOSFET TS7521 is not able to switch. Reason: feedback resistor 3523 is defective. Caution: be careful measuring on the gate of TS7521; circuitry is very high ohmic and can easily be damaged! (first connect measuring equipment to ground, then to the gate).

• Set is in hiccup mode and shuts down after 8 s. Blinking LED (set in SDM mode) indicates error 5. As it is unlikely that µP ‘POR’ and ‘+8V protection’ happen at the same

time, measure the ‘+8V’. If this voltage is missing, check transistor TS7480.

• Set is non-stop in hiccup mode Set is in over current mode; check the secondary sensing (opto coupler 7515) and the ‘MainSupply’ voltage. Signal ‘Stdby_con’ must be logic low under normal operation conditions and goes to high (3.3 V) under standby and fault conditions.

• Set turns on, but without picture and sound The screen shows snow, but OSD and other menus are okay. Blinking LED procedure indicates error 11, so problem is expected in the tuner (pos. 1000). Check presence of supply voltages. As ‘Vlotaux+5V’ at pin 5 and 7 are okay, ‘VT_supply’ at pin 9 is missing. Conclusion: resistor 3460 is defective.

• Set turns on, but with a half screen at the bottom. Sound is okay Blinking LED (set in SDM mode) indicates error 3. Check ‘Vlotaux+13V’ and ‘+50V’. If they are okay, problem is expected in the vertical amplifier IC7471. Measure with a scope the waveform on pin 17 of the UOC. Measure also at pin 1 of IC7471. If here the signal is missing, a defective resistor R3244 causes the problem.
