    1. SAFETY PRECAUTIONS GENERAL GUIDELINES 1. IMPORTANT SAFETY NOTICE There are special components used in this equipment which are important for safety. These parts are marked by in the Schematic Diagrams, Circuit Board Layout, Exploded Views and Replacement Parts List. It is essential that these critical parts should be replaced with manufacturer's specified parts to prevent X-RADIATION, shock, fire, or other hazards.

    transformer of adequate power rating as this protects the technician from accidents resulting in personal injury from electrical shocks. It will also protect Combination VCR from being damaged by accidental shorting that may occur during servicing. 3. When servicing, observe the original lead dress, especially the lead dress in the high voltage circuits.
  • Page 4 1. Plug the AC cord directly into the AC outlet. Do not use a isolation transformer for this check. 2. Connect a 1.5 kΩ Ω Ω Ω , 10 W resistor, in parallel with a 0.15µ µ µ µ F capacitor, between each exposed metallic part on the set and a good earth ground , as shown in Figure 1.
  • Page 5 of handling 25.0 kV without causing X-Radiation. NOTE : It is important to use an accurate periodically calibrated high voltage meter. 1. Reduce the brightness to minimum. 2. Set the SERVICE switch to SERVICE . 3. Measure the High Voltage. The meter reading should indicate 23.5 kV±1.5 kV. If the meter indication is out of tolerance, immediate service and correction is required to prevent the possibility of premature component failure.

  • Page 6: Prevention Of Electrostatic Discharge

    HORIZONTAL OSCILLATOR DISABLE CIRCUIT The positive DC voltage, supplied from the D503 cathode for monitoring high voltage, is applied to the IC5301 Pin11 through R503 and R5504. Under normal conditions, the voltage at IC5301 Pin 11 is less than approx 3 V. If the high voltage at Flyback Tr Pin 5 exceeds the specified voltage, the positive DC voltage which is supplied from the D503 cathode also increases.
