This Service Manual is designed for experienced repair technicians only and is not designed for use by the general public. It does not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting to service a product. Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product or products dealt with in this Service Manual by anyone else could result in serious injury or death.” The service technician is required to read and follow the “Safety Precautions” and “Important Safety Notice” in this Manual.

Important Safety Notice Special components are used in this television set which are important for safety. 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 are 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 antenna terminals, control shafts, etc. If the exposed metallic part has a return path to the chassis, the An Isolation Transformer should always be used reading should be between 240kΩ and 5.2MΩ. If the during the servicing of a Receiver whose chassis is not exposed metallic part does not have a return path to isolated from AC power line. Use a transformer of the chassis, the reading should be infinite. adequate power rating as this protects the technician from accidents resulting in personal injury from Leakage Current Hot Check (Fig. 1) electrical shocks. It will also protect the Receiver from being damaged by accidental shorting that may occur Plug the AC cord directly into the AC outlet. Do not use during servicing. an isolation transformer during the check. When servicing, observe the original lead dress, Connect a 1.5kΩ 10 watt resistor in parallel with a especially in the high voltage circuit. Replace all 0.15µF capacitor between an exposed metallic part damaged parts (also parts that show signs of and ground. Use earth ground, for example a overheating.) water pipe. Always Replace Protective Devices, such as Using a DVM with a 1000 ohms/volt sensitivity or fishpaper, isolation resistors and capacitors, and higher, measure the AC potential across the resistor. shields after servicing the Receiver. Use only Repeat the procedure and measure the voltage manufacturer’s recommended rating for fuses, circuits present with all other exposed metallic parts. breakers, etc. Verify that any potential does not exceed 0.75 volt High potentials are present when this Receiver is RMS. A leakage current tester (such a Simpson Model operating. Operation of the Receiver without the rear 229, Sencore Model PR57 or equivalent) may be used cover introduces danger for electrical shock. Servicing in the above procedure, in which case any current should not be performed by anyone who is not measure must not exceed 0.5 milliamp. If any thoroughly familiar with the necessary precautions measurement is out of the specified limits, there is a when servicing high-voltage equipment. possibility of a shock hazard and the Receiver must be Extreme care should be practiced when Handling the repaired and rechecked before it is returned to the Picture Tube. Rough handling may cause it to implode customer. 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. Figure 1. Hot Check Circuit The Test Picture Tube used for servicing the chassis at the bench should incorporate safety glass and X-ray Radiation magnetic shielding. The safety glass provide shielding for the tube viewing area against X-ray radiation as WARNING: The potential source of X-ray radiation in the well as implosion.
