Service should not be attempted by anyone not familiar with the precautions necessary when working on this type of equipment. READING SHOULD NOT EXCEED 750 mV. AC VOLTMETER (5000 ohms per volt or more sensitivity) The following precautions must be observed: 1. An isolation transformer must be connected in the power line between the receiver and the AC line before any service is performed on the receiver. TELEVISION RECEIVER 2. Comply with all caution and safety-related notes provided on the side of the cabinet, inside the cabinet, on the chassis, and the picture tube. 1500 ohm 10 watt 3. When replacing a chassis in the cabinet, always be certain that all the protective devices are installed properly, such as control knobs, adjustment covers, shields and barriers. DO NOT OPERATE THIS TELEVISION RECEIVER WITHOUT THE PROTECTIVE SHIELD IN POSITION AND PROPERLY SECURED. 4. Before replacing the back cover of the set, thoroughly inspect the inside of the cabinet to see that no stray parts or tools have been left inside. Before returning any television to the customer, the service technician must perform the following safety checks to be sure that the unit is completely safe to operate without danger of electrical shock. ANTENNA COLD CHECK Remove AC plug from the 120 VAC outlet and place a jumper across the two blades. Connect one lead of an ohmmeter to the jumpered AC plug, and touch the other lead to each exposed antenna terminal (UHF and VHF antenna terminals). The resistance must measure between 1M ohm and 5.2M ohm. Any resistance value below or above this range indicates an abnormality which requires corrective action. LEAKAGE CURRENT CHECK Plug the AC line cord directly into a 120 VAC outlet. (Do not use an isolation transformer for this check.) Use an AC voltmeter, that has 5000 ohms per volt or more sensitivity. Connect a 1500 ohm 10 watt resistor, paralleled by a 0.15 µF 150 VAC capacitor, between a known good earth ground (water pipe, conduit, etc.) and all exposed metal parts of the cabinet (antennas, handle bracket, metal cabinet, screw heads, metal overlays, control shafts, etc.). Measure the AC voltage across the 1500 ohm resistor. The AC voltage should not exceed 750 mV. A reading exceeding 750 mV indicates that a dangerous potential exists. The fault must be located and corrected. Repeat the above test with the receiver power plug reversed. NEVER RETURN A RECEIVER TO THE CUSTOMER WITHOUT TAKING THE NECESSARY CORRECTIVE ACTION. Good earth ground such as a water pipe, conduit, etc. 0.15 µF 150V AC AC OUTLET To be touched to all of exposed metal parts. Voltmeter Hook-up for Leakage Current Check. X-RADIATION PRECAUTION The primary source of X-RADIATION in solid-state receivers is the picture tube. The picture tube is specially constructed to limit X-Ray emission. For continued X-RADIATION protection, the replacement tube must be the same type as the original (including the suffix letter in the part numbers). Excessive high voltage may produce potentially hazardous X-RADIATION. To avoid such hazards, the high voltage must be maintained within specific limits. Refer to the X-RADIATION WARNING NOTE on the CHASSIS SCHEMATIC in this service manual for specific high voltage limits. If the high voltage exceeds specified limits, check the components specified on the chassis schematic diagram and take the necessary corrective action. Carefully follow the instructions for the +B Voltage Check and the High Voltage Check to maintain the high voltage within the specified limits. HIGH VOLTAGE HOLD-DOWN TEST To prevent X-RADIATION from the picture tube due to excessive high voltage, a HOLD-DOWN circuit is provided in the high voltage circuit. Every time the receiver is serviced, the high voltage HOLD-DOWN circuit must be tested for proper operation. Refer to the HIGH VOLTAGE HOLDDOWN TEST in service adjustments. PRODUCT SAFETY NOTICE When replacing components in a receiver, always keep in mind the necessary product safety precautions. Pay special attention to the replacement of components marked with a star (★) in the parts list and in the schematic diagrams. To ensure safe product operation, it is necessary to replace those components with the exact same PARTS. —2— SERVICE ADJUSTMENTS GENERAL This set has an on-screen Service Menu system included in the CPU that allows remote operation for most of the service adjustments.

Connect receiver to 120V AC line. Tune receiver to active channel. Reset the picture controls to the Auto levels. 2. Check that the voltage measured between TP7 and TE7 (ground side) is within 16.5 VDC to 21 VDC. If the voltage is out of this range, the Hold-Down Circuit must be checked. 3. Connect a DC Voltage supply to TP7 and TE7 through a 100 ohm 1/4W resistor. Adjust the DC voltage to 23 VDC. The receiver should shutdown, losing raster and sound. Then the receiver should turn off automatically. This reaction indicates that the Hold-Down circuit is functioning properly. If the receiver does not shutdown, a malfunction is indicated and its cause must be found and corrected. 4. To obtain picture again, remove the DC Supply and wait a few minutes. Now turn on the receiver. 7. Turn off the receiver and disconnect the AC power cord (AC 120V line). 8. Connect oscilloscope CH1 to TP317 and CH2 to TP318 and ground. 9. Connect an MTS TV/Stereo generator to antenna terminal. 10. While pressing the Menu key, reconnect the AC power cord. The Service Menu will now appear. 11.

Separation Adjustments SERVICE HINTS POWER FAILURE DETECTOR This unit is equipped with a Power Failure Detector function included in the CPU which checks for an abnormal condition in the chassis power supplies, including the power supply derived from the Horizontal Output Transformer. If, while the power is on, a failure is caused by any of the following that results in a low voltage supply, the CPU will turn the unit off in 1.5 seconds to prevent further damage: • Failure within the power supply circuits. • A short circuit in the load side from the supply. • Stoppage of the Horizontal Output Oscillator caused by the X Radiation protection Hold-Down Circuit. If, while the power is off, the power is switched on and any of these failures remains uncorrected, the CPU will shut off the power within three seconds. Check the following if the unit is turned off by the power failure detector. 1. Disconnect the AC power cord (120V AC line) for at least 10 seconds. 2. Connect a DC Voltmeter to the following TEST POINTS. TJ6 D002 Cathode D429 Cathode 5V 15V 5V 3. Press the Power key and check for the proper voltage supplies. 4. If any of these voltages is low, the power failure detector should turn the unit off within three seconds. 5. Check all circuits listed above. Note: This unit is equipped with a Power Surge Protection feature included in the CPU. If power failure occurs three times within 15 minutes, the CPU will automatically stop functioning to help prevent secondary damage. (TV will not turn on by pressing the power key.) To reset the operating programs within the CPU, disconnect the AC power cord for at least 10 seconds. — 11 — MECHANICAL DISASSEMBLIES CABINET BACK REMOVAL CHASSIS REMOVAL 1.
