    SAFETY PRECAUTIONS

    Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by inthe Schematic Diagram and Replacement Parts List. It is essential that these special safety parts should be replaced with the same components as recommended in this manual toprevent X-RADIATION, Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.

    General Guidance

    An isolation Transformer should always be used duringthe servicing of a receiver whose chassis is not isolated fromthe AC power line. Use a transformer of adequate power ratingas this protects the technician from accidents resulting inpersonal injury from electrical shocks.

    It will also protect the receiver and its components from beingdamaged by accidental shorts of the circuitry that may beinadvertently introduced during the service operation.

    If any fuse (or Fusible Resistor) in this TV receiver is blown,replace it with the specified.

    When replacing a high wattage resistor (Oxide Metal FilmResistor, over 1W), keep the resistor 10mm away from PCB.

    Keep wires away from high voltage or high temperature parts.

    Due to high vacuum and large surface area of picture tube,extreme care should be used in handling the Picture Tube.Do not lift the Picture tube by its Neck.

    X-RAY Radiation

    Warning:

    To determine the presence of high voltage, use an accuratehigh impedance HV meter.

    Adjust brightness, color, contrast controls to minimum. Measure the high voltage. The meter reading should indicate 23.5 1.5KV: 14-19 inch, 26 1.5KV: 19-21 inch,29.0 1.5KV: 25-29 inch, 30.0 1.5KV: 32 inchIf the meter indication is out of tolerance, immediate serviceand correction is required to prevent the possibility ofpremature component failure.

    Before returning the receiver to the customer,

    always perform an AC leakage current check on the exposedmetallic parts of the cabinet, such as antennas, terminals, etc.,to be sure the set is safe to operate without damage ofelectrical shock.

    Leakage Current Cold Check(Antenna Cold Check)With the instrument AC plug removed from AC source,connect an electrical jumper across the two AC plug prongs.Place the AC switch in the on position, connect one lead ofohm-meter to the AC plug prongs tied together and touch otherohm-meter lead in turn to each exposed metallic parts such asantenna terminals, phone jacks, etc. If the exposed metallic part has a return path to the chassis, themeasured resistance should be between 1M and 5.2M. When the exposed metal has no return path to the chassis thereading must be infinite.An other abnormality exists that must be corrected before thereceiver is returned to the customer.

    Leakage Current Hot Check (See below Figure) Plug the AC cord directly into the AC outlet.Do not use a line Isolation Transformer during this check. Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitorbetween a known good earth ground (Water Pipe, Conduit, etc.)and the exposed metallic parts.Measure the AC voltage across the resistor using ACvoltmeter with 1000 ohms/volt or more sensitivity.Reverse plug the AC cord into the AC outlet and repeat ACvoltage measurements for each exposed metallic part. Anyvoltage measured must not exceed 0.75 volt RMS which iscorresponds to 0.5mA.In case any measurement is out of the limits specified, there ispossibility of shock hazard and the set must be checked andrepaired before it is returned to the customer.

    Leakage Current Hot Check circuit

    The source of X-RAY RADIATION in this TV receiver is theHigh Voltage Section and the Picture Tube.For continued X-RAY RADIATION protection, thereplacement tube must be the same type tube as specified inthe Replacement Parts List.
