Page 99: Safety Precautions
violation of law. 1. 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 injuryfrom electrical shocks. It will also protect the receiver from being damaged by accidental shorting that may occur during servicing.
Page 100 Leakage current cold check Unplug the A.C. 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 returnpath to the chassis, the reading should be between 240k and 5.2M .
Page 101: Service Notes
NOTE It is important to use an accurate, calibrated high voltage meter. Set the brightness, picture, sharpness and color controls to minimum. Measure the high voltage. The high voltage should be 29.25 ± 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 prematurecomponent failure.
Page 102 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.
Page 103 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.
Page 104 IMPORTANT To protect against possible damage to the solid state devices due to arching 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.

4. With “VOL” keys adjust the correct value according with the service adjustment table (see “Service Mode” section on page 15). 5. Change to the next ID switch register with “CH” keys and repeat the same procedure as step 4. 6.
Page 107 CAUTION - Pb free solder has a higher melting point than standard solder. Typically the melting point is 50 ~ 70 °F (30 ~ 40 °C) higher. Please use a high temperature soldering iron and set it to 700 ± 20 °F (370 ±...

Page 113 A-Board - Main chassis 1. Slide the chassis completely out of the guide rails. 2. Stand the receiver on its edge. The underside of the board is completely accessible for component replacement. Note: Some tie-wraps that secure the wire dressings may need to be unfastened for chassis removal. C-Board - CRT output The board plugs onto the socket on the CRT neck.
Page 114 3. Unplug the CRT 2nd anode button from the main board. 4. Remove the C-Board from the CRT base and unplug the black wires (CRT dag ground) C10 & C11. 5. Disconnect the speakers plug from the A-Board. 6. Lift the main chassis (A-Board) and all mounted boards completely out with the CRT board attached.

10. Chassis service adjustment procedures All service adjustments are factory preset and should not require adjustment unless controls and/or associated components are replaced. Note: Connect the (-) lead of the voltmeter to the appropriate ground. Use IC801’s heat sink when the HOT ground symbol is used. Otherwise, use COLD ground (Tuner shield, IC451’s heat sink or FA2).
Page 117 Note: Components and test points within doted areas are located on trace side. B+ voltage check 1. Set the BRIGHT and PICTURE to minimum by using the PICTURE menu. 2. Connect the DVM between C825 (+ side) or TPD14 and cold ground.

Page 163 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 injuryfrom electrical shocks. It will also protect the receiver from being damaged by accidental shorting that may occur during servicing.
Page 164 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. Ifany 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.
Page 165 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. 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.
Page 166 How to replace flat ic (required tools) 1. Remove the solder from all of the pins of a Flat IC by using a desolder 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.

Page 168 Equipment: 1. Isolation transformer. 2. High voltage meter. 3. D.C. Ammeter 4. Short jumper. 5. HHS jig (See figure below). Diode Connection Jumper. Preparation: 1. Make sure the receiver is turned off. 2. Connect the receiver to an isolation transformer. 3.
Page 169 8. Slowly increase AC voltage at the input of the isolation transformer and confirm HHS voltage measure 31kV for 20” models and 33kV for 25” models. 9. Turn power off and remove jigs. 3. EEPROM replacement If a new EEPROM integrated circuit is replaced for servicing, follow the next procedure once that the memory is properly assembled: 1.
Page 170 7. Once that all 3 registers are set with the correct address value, perform all of the remaining adjustments and servicing. IMPORTANT: Correct ID switch configuration should be input when replacing EEPROM for each television model, otherwise if wrong values are configured, the television software will not function accordingly and properly.

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.
Page 183 Convergence Magnets and Wedges Location 12. Service mode (electronic adjustments) This receiver has electronic technology using the IC bus concept. It performs as a control function and it replaces many mechanical controls. Instead of adjusting mechanical controls individually, many of the control functions are now performedby using “on screen display menu”.
Page 184 7. Press POWER on the remote control to display the service adjustment modes menu, select adjustment by pressing the volume right/left buttons and channel up/down buttons on the remote and ACTION to enter the adjustment. Exiting the service mode: This TV goes out from service mode when it is unplugged or turned OFF. To exit the service mode, turn the TV OFF from or unplug the TV from A.C.
