These parts are identified on the schematic diagram by the symbol and printed in BOLD TYPE on the replacement part list. It is essential that these critical parts be replaced with the manufacturer’s specified replacement part to prevent X-ray radiation, shock, fire or other hazards. Do not modify the original design without the manufacturer’s permission. Safety Precautions General Guidelines An Isolation Transformer should always be used during the servicing of a Receiver whose chassis is not isolated from AC power line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personal injury from electrical shocks. It will also protect the Receiver from being damaged by accidental shorting that may occur during servicing. When servicing, observe the original lead dress, especially in the high voltage circuit. Replace all damaged parts (also parts that show signs of overheating.) Always Replace Protective Devices, such as fishpaper, isolation resistors and capacitors, and shields after servicing the Receiver. Use only manufacturer’s recommended rating for fuses, circuits’ breakers, etc. High potentials are present when this Receiver is operating. Operation of the Receiver without the rear cover introduces danger for electrical shock. Servicing should not be performed by anyone who is not thoroughly familiar with the necessary precautions when servicing high-voltage equipment. Extreme care should be practiced when handling the Picture Tube. Rough handling may cause it to implode due to atmospheric pressure. (14.7 lbs per sq. in.). Do not nick or scratch the glass or subject it to any undue pressure. When handling, use safety goggles and heavy gloves for protection. Discharge the picture tube by shorting the anode to chassis ground (not to the cabinet or to other mounting hardware). When discharging, connect cold ground (i.e. DAG ground lead) to the anode with a well-insulated wire or use a grounding probe. Avoid prolonged exposure at close range to unshielded areas of the picture tube to prevent exposure to X-ray radiation. The Test Picture Tube used for servicing the chassis at the bench should incorporate safety glass and magnetic shielding. The safety glass provides shielding for the tube viewing area against X-ray radiation as well as implosion. The magnetic shield limits the X-ray radiation around the bell of the picture tube in addition to the restricting magnetic effects. When using a picture tube test jig for service, ensure that the jig is capable of handling 50kV without causing X-ray radiation. Before returning a serviced Receiver to the owner, the service technician must thoroughly test the unit to ensure that is completely safe to operate. Do not use a line isolation transformer when testing. Leakage Current Cold Check Unplug the AC cord and connect a jumper between the two plug prongs. Measure the resistance between the jumpered AC plug and expose metallic parts such as screwheads, antenna terminals, control shafts, etc. If the exposed metallic part has a return path to the chassis, the reading should be between 240k: and 5.2M:� If the exposed metallic part does not have a return path to the chassis, the reading should be infinite. Leakage Current Hot Check (Fig. 1) Plug the AC cord directly into the AC outlet. Do not use an isolation transformer during the check. Connect a 1.5k: 10-watt resistor in parallel with a 0.15PF capacitor between an exposed metallic part and ground. Use earth ground, for example a water pipe. Using a DVM with a 1000 ohms/volt sensitivity or higher, measure the AC potential across the resistor. Repeat the procedure and measure the voltage present with all other exposed metallic parts. Verify that any potential does not exceed 0.75 volt RMS. A leakage current tester (such a Simpson Model 229, Sencore Model PR57 or equivalent) may be used in the above procedure, in which case any current measure must not exceed 0.5 milliamp. If any measurement is out of the specified limits, there is a possibility of a shock hazard and the Receiver must be repaired and rechecked before it is returned to the customer. X-ray Radiation WARNING: The potential source of X-ray radiation in the TV set is in the High Voltage section and the picture tube. Note: It is important to use calibrated equipment including the high voltage meter. Set the brightness, picture, sharpness and color controls to Minimum. Measure the High Voltage. The high voltage should be 27.70kV ± 1.25kV. If the upper limit is out of tolerance, immediate service and correction is required to insure safe operation and to prevent the possibility of premature component failure. Horizontal Oscillator Disable Circuit Test This test must be performed as a final check before the Receiver is returned to the customer. See “Horizontal Oscillator Disable Circuit” on page 5.

4 - Service Notes Leadless Chip Component (Surface mount) Chip components must be replaced with identical chips due to critical foil track spacing. There are no holes in the board to mount standard transistors or diodes. Some chips capacitor or resistor board solder pads may have holes through the board, however the hole diameter limits standard resistor replacement to 1/8 watt. Standard capacitor may also be limited for the same reason. It is recommended that identical components be used. Chip resistors have a three-digit numerical resistance code - 1st and 2nd significant digits and a multiplier. Example: 162 = 1600 or 1.6k: resistor, 0 = 0: (jumper). Chip capacitors generally do not have the value indicated on the capacitor. The color of the component indicates the general range of the capacitance. Chip transistors are identified by a two-letter code. The first letter indicates the type and the second letter, the grade of transistor. Chip diodes have a two-letter identification code as per the code chart and are a dual diode pack with either common anode or common cathode. Check the parts list for correct diode number. Component Removal 1. Use solder wick to remove solder from component end caps or terminal. 2. Without pulling up, carefully twist the component with tweezers to break the adhesive. 3. Do not reuse removed leadless or chip components since they are subject to stress fracture during removal. Chip Component Installation 1. Put a small amount of solder on the board soldering pads. 2. Hold the chip component against the soldering pads with tweezers or with a miniature alligator clip and apply heat to the pad area with a 30 watt iron until solder flows. Do not apply heat for more than 3 seconds. How to Replace Flat-IC - Required Tools - 1. Remove the solder from all of the pins of a Flat-IC by using a de-solder braid. 2. Put the iron wire under the pins of the Flat-IC and pull it in the direction indicated while heating the pins using a soldering iron. A small awl can be used instead of the iron wire. 3. Remove the solder from all the pads of the Flat-IC by using a de-solder braid. 4. Position the new Flat-IC in place (apply the pins of the Flat-IC to the soldering pads where the pins need to be soldered). Properly determine the positions of the soldering pads and pins by correctly aligning the polarity symbol. 5. Solder all pins to the soldering pads using a fine tipped soldering iron. 6. Check with a magnifier for solder bridge between the pins or for dry joint between pins and soldering pads. To remove a solder bridge, use a de-solder braid as shown in the figure below. Note: These components are affixed with glue. Be careful not to break or damage any foil under the component or at the pins of the ICs when removing. Usually applying heat to the component for a short time while twisting with tweezers will break the component loose. Chip Components • Soldering iron • De-solder braids • Iron wire or small awl • Magnifier 珍惜眼前人 搜集整理 QQ:362399998 QQ群:12919880 - 5 - IMPORTANT: To protect against possible damage to the solid state devices due to arcing or static discharge, make certain that all ground wires and CRT DAG wire are securely connected. CAUTION: The power supply circuit is above earth ground and the chassis cannot be polarized. Use an isolation transformer when servicing the Receiver to avoid damage to the test equipment or to the chassis. Connect the test equipment to the proper ground ( ) or ( ) when servicing, or erroneous voltages will be measured. WARNING: This Receiver has been designed to meet or exceed applicable safety and X-ray radiation protection as specified by government agencies and independent testing laboratories. To maintain original product safety design standards relative to X-ray radiation and shock and fire hazard, parts indicated with the symbol on the schematic must be replaced with identical parts. Order parts from the manufacturer’s parts center using the parts numbers shown in this service manual, or provide the chassis number and the part reference number. For optimum performance and reliability, all other parts should be replaced with components of identical specification. Horizontal Oscillator Disable Circuit This chassis employs a special circuit to protect against excessive high voltage and beam current. If, for any reason, the high voltage and beam current exceed a predetermined level this protective circuit activates and detunes the horizontal oscillator that limits the high voltage. The over-voltage protection circuit is not adjustable. However, if components indicated by the symbol on the schematic in either the horizontal sweep system or the over-voltage protection circuit itself are changed, the operation of the circuit should be checked using the following procedure: Equipment needed to check the disabled circuit: 1. Voltmeter (0 - 200V scale) 2. High Voltage Meter (0- 50kV) 3. Variac or Isolation Transformer Procedure: 1. Tune in a station to verify that the horizontal is in sync. 2. Obtain a Monoscope pattern or a signal generator crosshatch pattern 3. Connect the voltmeter (-) lead to TPD2 and the (+) lead to TPD1 (junction of D555 anode, R556 & R557). Set Bright level to (0) and Picture for a 1.8-volt reading on the voltmeter. 4. Turn the Receiver “OFF”. Connect a jumper across IC803 pin 3 and pin 4. Apply +9V DC to cathode of D001. 5. Reduce the AC supply voltage to approximately 45V. Connect the high voltage meter to the CRT anode. (H.V. button). Note: Use the DAG Ground (C10 on the CRT Board) to connect the (-) lead of the meter. 6. Turn the Receiver “ON”. Slowly increase the AC supply voltage and verify that the high voltage does not exceed 34.0kV when horizontal just begins to pull out of sync. If the high voltage is not within the specified limit, the cause must be determined and corrected before the Receiver is returned to the customer. Remove jumper installed in Step 4. 珍惜眼前人 搜集整理 QQ:362399998 QQ群:12919880 - 6 - Receiver Feature Table FEATURE Chassis AP348M Tunning system 64K # of channels 181 Menu language Eng/Span/Fr Closed Caption X V-Chip X 75 : input X Remote Model # EUR511503 Picture tube A51KQN011X Black Face Regular Tube X Comb Filter 3 Line Digital H.

The complete procedure consists of: 1. Vertical Raster Shift Adjustment. (Only for Models with Purity/Convergence Assembly with 4 Pairs of Rings). 2. Initial static convergence. 3. Setting the purity. 4. Final static convergence. When the CRT or the Yoke is Replaced Place the yoke on the CRT neck (do not tighten the clamp). For a 2-piece assembly (see Fig. 23): Position purity/convergence assembly as shown and tighten clamp snugly. To reduce its magnetic field effect, remove the hot-melt glue seal on assembly and position like tabs of purity device together at 12 o’clock. For models using 4 pairs of rings, place the vertical raster shift tabs at 3 o’clock (90o from the purity and convergence tabs. (See Fig. 24 and Fig. 25.) For a 1-piece assembly (see Fig. 26): Position like tabs of purity devices together at 12 o’clock to reduce any magnetic field effect. (For better results, note part number and look for specifications at Service Center) For either assemblies: Turn the Receiver “ON”. Operate the Receiver for 60 minutes using the first Purity Check field (white screen) to stabilize the CRT. Fully degauss the Receiver by using an external degaussing coil. Slide the deflection yoke back and forth on the neck of the CRT until it produces a near white, uniform raster. Vertical Raster Shift Adjustment (Only for Models with Purity/Convergence Assembly with 4 Pairs of Rings). Apply a green pattern with a horizontal line, adjust the Deflection Yoke so that has no tilt, and then secure it. Adjust centerline of the pattern with the mechanical center of the CRT, this center is determined by two marks at the side edges of the screen. To adjust the line, once the vertical raster shift tabs are place at 3 o’clock to reduce its magnetic field effect (see Fig. 24 and Fig. 25) open the tabs the same angle from the center, until the centerline of the pattern becomes a straight line, centered with the marks of the CRT. (See Fig. 27) Figure 23. Positioning of Purity/Convergence Assembly (2-piece assembly) Figure 24. Positioning of Purity/Convergence Assembly (4 Pairs of Rings) Figure 25. Positioning of Purity/Convergence Assembly (4 Pairs of Rings) Figure 26. Positioning of Purity/Convergence Assembly (1-piece assembly) Figure 27.

Observe misconvergence at center of the screen only. Adjust the R & B pole magnets; by separating tabs and rotating to converge blue with red. Adjust the R & B and R & B & G pole magnets: by separating tabs and rotating to converge blue and red (magenta) with green. Note: Precise convergence at this point is not important. Purity Adjustment When the Receiver is in the Service Mode for making electronic adjustments, press Recall on the Remote Control to enter Purity Check. (See “Service Adjustments (Electronic Controls)” on page 28). Operate the Receiver for 60 minutes using the first Purity Check field (white screen) to stabilize the CRT. Fully degauss the Receiver by using an external degaussing coil. Press Recall on the Remote Control again until the Purity Check (green screen) appears. For a 2-piece assembly (see Fig. 23): Loosen the deflection yoke clamp screw and move the deflection yoke back as close to the purity magnet as possible. Adjust the Purity rings to set the vertical green raster precisely at the center of the screen. (See Fig. 28.) Slowly move the deflection yoke forward until the best overall green screen is displayed. For a 1-piece assembly (see Fig. 26): Slowly move the deflection yoke and purity rings assembly toward the CRT board and adjust the purity magnet rings to set vertical green raster at center of screen. (See Fig. 28.) Gradually move the deflection yoke & purity rings forward and adjust for best overall green screen. Continue from here for either assemblies: Tighten the deflection yoke clamp screw. Press Recall on the Remote Control again until the purity check (blue screen) and (red screen) appear and observe that good purity is obtained on each respective field. Press Recall on the Remote Control again until Purity check (white screen) appears. Observe the screen for uniform white. If purity has not been achieved, repeat the above procedure. Final Convergence Procedure (See Fig. 29 through Fig. 32): Note: Vertical size and focus adjustments must be completed prior to performing the convergence adjustment. Connect a dot pattern generator to the Receiver. The Brightness level should not be higher than necessary to obtain a clear pattern. Converge the red and the blue dots at the center of the screen by rotating the R & B pole Static Convergence Magnets. Align the converged red/blue dots with the green dots at the center of the screen by rotating the R & B & G pole Static Convergence Magnets. Melt wax with soldering iron to reseal the magnets. Slightly tilt vertically and horizontally (do not rotate) the deflection yoke to obtain a good overall convergence. If convergence is not reached at the edges, insert permalloy (see following section) from the DY corners to achieve proper convergence. Recheck for purity and readjust if necessary. After vertical adjustment of the yoke, insert wedge at 11 o’clock position, then make the horizontal tilt adjustment. Secure the deflection yoke by inserting two side wedges at 3 and 7 o’clock positions. Apply adhesive between tab (thin portion) of wedge and CRT and place tape over the tab to secure to the CRT. Permalloy Convergence Corrector Strip (Part No. 0FMK014ZZ) This strip is used in some sets to match the yoke and CRT for optimum convergence. If the yoke or CRT is replaced, the strip may not be required. First converge the set without the strip and observe the corners. If correction is needed: 1. Place strip between CRT and yoke, in quadrant needing correction. Slowly move it around for desired results. 2. Press adhesive tightly to the CRT and secure with tape. Figure 28.

Apply the following signal from the RF signal generator: Video: 100 IRE flat field, 30% modulation. Audio: 300Hz, 100% modulation, monaural (70 ± 5dB, 75: OPEN, P/S 10dB). 2. Adjust the MTS Input Level Adjustment (M0) until the voltage measured is 106 ± 6.0mV RMS. Stereo Separation Adjustment (M1 & M2) Preparation: 1. Connect an RF signal generator to the RF antenna input. 2. Connect a scope to TPE10. Procedure: 1. Select Stereo Mode in Audio menu 2. Apply the following signal from the RF signal generator: Figure 42. Cathode Waveform, Adjustment Waveform Detail 175V DC 0V DC Figure 43. Filter Jig TPE1 (A-BOARD) TPE10 Figure 44.

Adjust the MTS Low-Level Separation Adjustment (M2) until the amplitude displayed on the scope is minimum. 4. Apply the following signal from the RF signal generator: Video: 100 IRE flat field, 30% modulation. Audio: 3KHz, 100% modulation, stereo (left only) (70 ± 5dB, 75: OPEN, P/S 10dB). 5. Adjust the MTS High-Level Separation Adjustment (M1) until the amplitude displayed on the scope is minimum. 6. Repeat above steps 2 through 5 until the amplitude is at minimum for both signals. Clock Adjustment (Sb) Preparation: Connect the frequency counter from TPS1 (IC001 Pin 13) to cold ground ( ). Note: Frequency Counter probe capacitance should be 8pF or less. Procedure: 1. Turn the Receiver “OFF” with the AC power applied. 2. Measure TPS1 (IC001 pin 13) for the frequency of the waveform and record the reading. Note: Pin 13 measurement must have at least four digits of resolution following the decimal point. Example: 000.0000 3. Turn the Receiver back “ON”. 4. Place the Receiver into Service Mode for making electronic adjustment, select the Clock Adjustment DAC (Sb). 5. Calculate and set Sb based on the following formula: Note: Pin 13 measurement will not change regardless of the value stored in Sb. Vertical Size (B7) Adjust the VERTICAL SIZE DAC control, B7, until the top and the bottom edges of the raster are visible and touch the bezel edge. Best results can de obtained with a round test pattern. Linearity adjustment is done automatically when the size is being adjusted. Service Adjustments (Mechanical Controls) VCO Field Alignment L105 (IC101 pins 35 & 36) 1. Turn Receiver “ON” and let it warm up for a minimum of 20 minutes prior to continuing with the adjustments. 2. Connect a balance antenna and select a midband channel (Ch 10, 11 or 12). 3. Attenuate the signal strength for a weak noisy video. 4. While observing the picture tube, adjust L105 until best picture appears. 5. Change channels and observe that they are tuning properly. 6. If the channel monitored is not clear, repeat steps 1, 3 and 4 while applying a stronger signal. Focus (part of T551) Preparation: Connect a Signal generator and select a dot pattern. Procedure: Adjust the FOCUS control to obtain the sharpest and clearest dot pattern. a. Adjust for best center. b. Adjust for best area between the center and top right corner.
