Safety Instructions, Warnings, and Notes
2. Safety Instructions, Warnings, and Notes
Index of this chapter: 2.1 Safety Instructions 2.2 Maintenance Instructions 2.3 Warnings 2.4 Notes 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.
2.1
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 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. · 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.
2.3
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).
V
E_06532_007.eps 250304
Figure 2-1 Discharge picture tube · 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 prevents circuits from becoming unstable.

2.4.1
Notes
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.

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:

Safety Instructions, Warnings, and Notes
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
Lead-free Solder Philips CE is producing lead-free sets (PBF) from 1.1.2005 onwards. Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 5 and 6 refer to the production year, digits 7 and 8 refer to production week (in example below it is 1991 week 18).
MODEL : 32PF9968/10
MADE IN BELGIUM 220-240V ~ 50/60Hz 128W VHF+S+H+UHF
clean 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 shortly 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 temperatureprofile, 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 Alternative BOM identification In September 2003, Philips CE introduced a change in the way the serial number (or production number, see Figure 2-2) is composed. From this date on, the third digit in the serial number (example: AG2B0335000001) indicates the number of the alternative BOM (Bill of Materials used for producing the specific model of TV set). 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 O.E.M.s. By looking at the third digit of the serial number, the service technician can see if there is more than one type of B.O.M. used in the production of the TV set he is working with. He can then consult the At Your Service Web site, where he can type in the Commercial Type Version Number of the TV set (e.g. 28PW9515/12), after which a screen will appear that gives information about the number of alternative B.O.M.s used. If the third digit of the serial number contains the number 1 (example: AG1B033500001), then there is only one B.O.M. version of the TV set on the market. If the third digit is a 2 (example: AG2B0335000001), then there are two different B.O.M.s. Information about 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. 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.

Figure 2-3 Lead-free logo 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 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 of 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 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

Index of this chapter: 5.1 Test Points 5.2 Service Modes 5.3 Error Codes 5.4 Fault Finding and check again if the CPU puts I2C data on the I2C bus. If the problem seems to be in the deflection circuits, it may also be caused by randomly interrupted antenna signals. 5.4.4 The TV set turns ON and OFF randomly when you attempt to turn ON the TV set. · The chassis power supply of the horizontal deflection part of the circuit has loose or bad (corroded) connections, resulting in irregular power supply. Check also if the power supply to the CPU is not interrupted randomly. If the supply voltage is not available or not normal, change Q602 and Q603.
5.1
Test Points
See chapter 6 "Block Diagrams, Testpoint Overviews, and Waveforms". Perform measurements under the following conditions: · Service Default Mode. · Video: colour bar signal. · Audio: 3 kHz left, 1 kHz right.
·
5.4.5
The TV set is turned ON (indicator light is ON) but no picture and sound is observed. · Measure the collector voltage of Q303 for 140 V to eliminate the possibility that the horizontal deflection circuit is causing the problem. During normal operation, the collector voltage should be in the range of 110 V. Next, measure the horizontal pulse output voltage at Pin11 of the digital board output terminal. In normal operation, the voltage is in the range of 2.8 VAC. If this is the case, check if the horizontal output transistors Q301 and Q302 are switching normally between their ON and OFF states.
5.2
Service Modes
This chassis does not contain a specific Service Mode. Service and Alignment of the TV set can be done via the Factory Mode by the service technician, see further down in this manual.
·
5.3
Error Codes
Not applicable. 5.4.6
The TV displays a blue screen when it is turned ON. The TV set is equipped with a video noise-reduction circuit. Therefore, when no video and synchronization signal is detected, the CPU decodes it as "no signal detected". Check the antenna signal, the tuner and the IF amplifier circuit. Replace UOCIII and the peripheral components of the IF circuit, if needed.
5.4
5.4.1
Fault Finding
Big Snow Dots Visible on the Screen. Analysis and repair action: according to the problem phenomena, first check: (1) Is the antenna signal normal? (2) Is the tuner and intermediate-frequency circuit power supply working normally? (3) Is the AGC circuit of tuner working normally? (4) Is there a problem with the I2C data stream? (5) Is there an electricity leak in the circuit layers?
5.4.7
Horizontal Deflection Transistor is Defect. Analysis and repair action: if the deflection time is decreased too much, this may result in an over-voltage in the deflection circuit and a defective horizontal transistor. In this case, check C303, C304 and C317 for defects.
5.4.2
Picture becomes more green after the TV set has been on for more than one hour. 5.4.8 Analysis and repair action: according to the problem phenomena, check the following: (1) Is the antenna signal normal? (2) If you suspect that there is a heating problem in the channel circuit, or the circuits after the tuner (colour decoder), use a blower to reduce the temperature, and check if this has any effect. (3) Interrupt and reconnect the antenna signal to find out if the trouble is in the tuner or the AGC circuit. (4) Is there a problem with the I2C data stream? (5) Also check the horizontal deflection pulse.
In the picture appears a horizontal bright line. · · Check the vertical deflection loop for poor contact. Check the vertical IC power supply for +15 V and -15 V. If no voltage is present, check R331 for open circuit. If the voltage is low, change the vertical deflection IC. If the problem still exists, change the surrounding components in the circuit (eg. C325, C326 etc.).
5.4.9
Poor picture and sound quality. · · Check if the signal line contact is good. Next, use a conductor to touch the IF input of the tuner, if no effect is observed, the problem is suspected to be in the IF amplification circuit. Use a 0.01 uF capacitance to short the input and output terminals of SAW101 to isolate if the SAW filter is faulty. If the picture and sound condition does not improve, check the AGC circuitry, and replace resistors and capacitors when needed.
5.4.3
White Raster Only (no Picture Visible). Analysis and repair action: if the antenna signal is normal: according to the problem phenomena, the trouble range can be divided into six parts: the CPU, the memory chips, the data transport of the I2C circuit, the horizontal and vertical deflection pulse circuit, the CRT power supply circuit, and finally the entire video amplification circuit (including the IF stage). If the CPU or memory have problems, this will also cause problems of I2C data. If the problem still cannot be eliminated, check the load of the I2C lines, namely, the other ICs that are connected to the I2C bus (they may also have a defect and cause a too heavy load on the I2C bus. Interrupt the I2C bus to reduce the load ·
5.4.10 The colour disappears after the TV is turned ON for a while. · · Check if the colour system is selected correctly. If you suspect the 24.576 MHz crystal, replace it.
Service Modes, Error Codes, and Fault Finding
· If there is no effect, then replace suspected components in the decoding and colour circuitry.

5.4.11 Soft volume can still be heard, even when volume level is reduced to "0". · Check if the peripheral networks connected to pin 122 (MUTE) and pin128 (AV MUTE) of UOCIII are well connected. Proceed to check the audio control and power amplifier module (IC401); check the surrounding components of IC401. For example check C407, if it is correctly connected and shows no leakage. Does Q401 switch normally between its saturation and cut-off states?.
·
5.4.12 No colour in AV state · · · · First, check the video input module. Second, check the A-D module. Next, check the video processor module. Finally, check if UOCIII has a defect.
