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.

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).

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.

2.42.4.1

NotesGeneral 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 color 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

2.2

Maintenance InstructionsWe 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:

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

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 is being removed, it is essential when removing an (LF)BGA, that 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 risk 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 been shown to result in problems during re-soldering. 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 neighboring components, it may be necessary to reduce some temperatures and times.

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 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 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 90C) for drying (think of ESD-protection!). Do not re-use BGAs at all!

Safety Instructions, Warnings, and Notes 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. 2.4.5 Alternative BOM identification In September 2003, Philips CE introduced a change in the way the serial number (or production number, see Figure 2-1) 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. 2.4.6 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.

Brief Introduction of the ChassisChassis block diagram

G_16340_010.eps 100306

Figure 9-1 Chassis block diagram 9.1.2 Power Supply Section This section mainly consists of IC STR-W6735 (IC801). Transformer (T803). Bridge rectifier (DB801). Accessory circuits. The supply voltage for this chassis should be AC 110V. The allowed voltage range is 90V to 140V, the frequency range is 50/60Hz. The AC power with high/low frequency interference goes through an RC filter, consisting of C801, T801, C802, R801, and T802. The filter removes the high/low frequency interference. Then DB801 transforms the AC power to DC power. T803 and IC 801 work in standby state. T803 will provide a power voltage to IC101. IC101 scans for the "KEY IN" signal (Pin 3 of IC101) from the ON/OFF switch on the keyboard. If "KEY IN" = "power on" signal, pin 64 (IC101) will generate a signal to drive the photo coupler (IC8021). It acts as a feed back circuit (feed back to Pin 6 of IC801) for controlling IC801 to adjust MOSFET. Transformer T803 provides the following voltages: +13V voltage from Pin16. +130V (B+) voltage from Pin1. +12V from Pin 15. Pin 15 is also connected to two Positive Voltage Regulators (IC201, IC202) in-series. The outputs of these regulators are +9V and +5V respectively. The picture below shows IC201 and IC202:

Figure 9-3 Pre-amplifier circuit 9.1.4 Sound Process Section The SIF signal is sent out together with the TV signal from Pin30 of IC101. It passes through Q203, R225. X202 and a High-pass filter (consisting of C254, L206, C253) filters out the video signal and low frequency interference.

From Pin58 of IC101 the I2C bus clock signal goes to the tuner. The tuner works during the clock time. IC101 will send out a data signal from Pin57 to control the tuner's working state by controlling the +33V voltage. +33V is provided from Pin10 of T803. That voltage is put into the tuner at Pin7. A circuit inside the tuner transforms +33V into a voltage between 0 and +33V (as a function of the data, sent by IC101). The AGC signal is a close loop control voltage that keeps the amplitude of the signal constant. Output of tuner is the Intermediate Frequency signal (IF signal). The IF signal will pass pre-amplifier circuit (refer to the picture below). The amplified IF signal passes the SAW filter and is then sent to IC101 Pin41/42. IC101 creates a CVBS signal and sends it out from Pin30. CVBS will be selected by IC901, and then pass from Pin13 of IC901 to Pin20/24 if IC101. IC101 will demodulate the CVBS signal into an R, G, B signal. Next IC101 will send this R, G, B signal from Pin50/51/52 to the CRT board.

Figure 9-4 Sound process section 1 SIF will be finally sent into Pin2 of IC1001. An analog automatic gain control circuit (AGC) allows a wide range of input levels. The analog-to-digital conversion of the IF sound signal is done by an A/D-converter. The high pass filter, formed by a coupling capacitor at SIF_IN1+ suppresses video components. IC1001 is controlled via the I2C bus slave interface. The AV sound signal will be directly sent to Pin37/38 or Pin40/ 41 of IC1001. Q901/2 and Q903/4 form Emitter-Follower circuits to provide a better load ability. The (analog) sound signal will go from Pin26/27 of IC1001 to Pin4/12 of IC602. IC602 is a dual bridge amplifier. The output voltage of IC602 drives the speakers. The volume is adjusted via the I2C bus.

Vertical Output Section This section mainly consists of IC301 (TDA8172), the Vertical Coil and the related circuit. The supply voltage of IC301 are +14V and -14V. These two voltages are provided by the LOT section. For the vertical scan, IC101 creates a Saw-tooth waveform at Pin16. This is the input signal of IC301. The main task of IC101 is to create the vertical scan waveform. The output signal of IC301 drives the Vertical Coil. If IC301 works in normal state, Pin6 will send a square-signal to maintain a high voltage at D214. If it does not, D214 will get a low voltage, Pin2 of IC101 senses this change and IC101 sends out a standby signal.

9.1.6

Horizontal Output and LOT Section The horizontal drive pulse is a square wave. IC101 creates this waveform at Pin13. Via Q401 the signal goes to the input of Q411. Q411 is a horizontal output triode with a damper inside. The signal from Pin C of Q411 drives the Horizontal Coil. When Q411 goes into cut-off state, a sub-coil inside the LOT will generate an EHT by inductance.
