Precautions, Notes, and Abbreviation List Index of this chapter: 3.1 Safety Instructions 3.2 Maintenance Instructions 3.3 Warnings 3.4 Notes 3.5 Abbreviation List 3.1 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. 3.2 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. 3.3 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 V DC ). Discharge until the meter reading is 0 V (after approx. 30 s). Figure 3-1 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. • 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. 3.4 Notes 3.4.1 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 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 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. V E_06532_007.eps 250304 Precautions, Notes, and Abbreviation List EN 4 SK4.1L CA 3. 2009-Jul-24 3.4.2 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. 3.4.3 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 400°C. – 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 360°C - 380°C is reached and stabilized 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 clear the solder-joint from old tin and re-solder with new tin. 3.4.4 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 3-2 Serial number (example) 3.4.5 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! 3.4.6 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. 3.5 Abbreviation List 0/6/12 SCART switch control signal on A/V board. 0 = loop through (AUX to TV), 6 = play 16 : 9 format, 12 = play 4 : 3 format AARA Automatic Aspect Ratio Adaptation: algorithm that adapts aspect ratio to remove horizontal black bars; keeps the original aspect ratio ACI Automatic Channel Installation: algorithm that installs TV channels directly from a cable network by means of a predefined TXT page ADC Analogue to Digital Converter AFC Automatic Frequency Control: control signal used to tune to the correct frequency AGC Automatic Gain Control: algorithm that controls the video input of the feature box AM Amplitude Modulation AP Asia Pacific AR Aspect Ratio: 4 by 3 or 16 by 9 ASF Auto Screen Fit: algorithm that adapts aspect ratio to remove horizontal black bars without discarding video information ATSC Advanced Television Systems Committee, the digital TV standard in the USA ATV See Auto TV Auto TV A hardware and software control system that measures picture content, and adapts image parameters in a dynamic way AV External Audio Video AVC Audio Video Controller E_06532_024.eps 260308 MODEL : PROD.NO: ~ S 32PF9968/10 MADE IN BELGIUM 220-240V 50/60Hz 128W AG 1A0617 000001 VHF+S+H+UHF BJ3.0E LA Precautions, Notes, and Abbreviation List EN 5 SK4.1L CA 3. 2009-Jul-24 AVIP Audio Video Input Processor B/G Monochrome TV system.

Circuit Descriptions Index of this chapter: 7.1 Introduction 7.2 The various circuits 7.1 Introduction The SK4.1L CA is a CRT TV based on the 3P62 platform. In this chapter, only a general description of the various circuits is given. For more detailed information, see the circuit diagrams in this manual. 7.1.1 Main Board Diversity It should be noted that the main board of sets with a 21SL9 styling differs slightly from the main board of the (older) SL7 sets. The differences are depicted in Table 7-1. For the relation between set type and -style, refer to Table 2-1. Table 7-1 Delta’s 21SL9 versus SL7 sets 7.2 The various circuits 7.2.1 Tuner The function of the tuner is to select the channel to be received and suppress the interference of neighboring channels, to amplify the high frequency signal, to improve the receiving sensitivity and SNR, and to generate a PIF signal through frequency conversion. 7.2.2 IF Channel The IF Channel mainly ensures the sensitivity and selectivity of the complete TV set. The IF AMP integrated in the UOCIII is made up of a three-stage dual-differential amplifier with a gain value above 70 dB, a SNR of 55 dB and a bandwidth of 7 MHz. The video demodulation circuit is made from the built-in PLL Sync Detector. The spectrum of the demodulation carrier is unitary and it is not affected by the content of the video signal. The tuner features stable receptivity while the signal output from the video detector features high fidelity. The built-in PLL circuit of the UOCIII generates a 38.0 MHz or 38.9 MHz demodulation reference signal for the sync detector to demodulate the video signal; this is called “PLL sync demodulation”. 7.2.3 Sound Channel An external ceramic filter is used to select the second SIF signal for the sound channel of UOCIII from the signal output of the video detector. The audio signal is obtained after limiting amplification and demodulation by the intermediate frequency detector for the SIF signal, and then the audio signal is fed to the BTSC stereo/SAP decoder TDA9850. From that it is output to the audio amplifier TFA9842, which drives the speakers to provide the sound. The intermediate frequency detector and volume-control attenuator that are built in the UOCIII are set and adjusted via the CPU. 7.2.4 BTSC stereo/SAP decoder Input Level Adjustment The composite input signal is fed to the input level adjustment stage. The control range is from -3.5 to +4.0 dB in steps of 0.5 dB. The maximum input signal voltage is 2 V (RMS). Stereo Decoder The output signal of the level adjustment stage is coupled to a low-pass filter which suppresses the baseband noise above 125 kHz. The composite signal is then fed into a pilot detector/ pilot cancellation circuit and into the MPX demodulator. The main L + R signal passes a 75 ms fixed de-emphasis filter and is fed into the dematrix circuit. The decoded sub-signal L - R is sent to the stereo/SAP switch. To generate the pilot signal the stereo demodulator uses a PLL circuit including a ceramic resonator. The stereo channel separation is adjusted by an automatic procedure to be performed during set production. The stereo identification can be read by the I 2 C-bus. Two different pilot thresholds (data STS = 1; STS = 0) can be selected via the I 2 C-bus. SAP Demodulator The composite signal is fed from the output of the input level adjustment stage to the SAP demodulator circuit through a 5fH band-pass filter. The demodulator level is automatically controlled. The SAP demodulator includes an internal field strength detector that mutes the SAP output in the event of insufficient signal conditions. The SAP identification signal can be read by the I 2 C-bus. Noise Detector The composite input noise increases with decreasing antenna signal. This makes it necessary to switch stereo or SAP off at certain thresholds. These thresholds can be set via the I 2 C- bus. With ST0 to ST3 the stereo threshold can be selected and with SP0 to SP3 the SAP threshold. A hysteresis can be achieved via software by making the threshold dependent of the identification bits STP and SAPP. Mode Selection The stereo/SAP switch feeds either the L - R signal or the SAP demodulator output signal via the internal dbx noise reduction circuit to the dematrix/switching circuit. Different switch modes provided at the output pins OUTR and OUTL are available. dbx Decoder The dbx circuit includes all blocks required for the noise reduction system in accordance with the BTSC system specification. The output signal is fed through a 73 ms fixed de- emphasis circuit to the dematrix block. SAP Output Independent of the stereo/SAP switch, the SAP signal is also available at pin SAP. At SAP, the SAP signal is not dbx decoded. The capacitor at SDE provides a recommended de- emphasis (150 ms) at SAP. Integrated Filters The filter functions necessary for stereo and SAP demodulation and part of the dbx filter circuits are provided on-chip using transconductor circuits. The required filter accuracy is attained by an automatic filter alignment circuit. 7.2.5 CRT Drive Circuit In the driver circuit, both the voltage and current of the R/G/B signal are amplified, after which the CRT drive circuit modulates the cathode beam current of the CRT.
