SAFETY PRECAUTIONS
IMPORTANT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in
the 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 to
prevent X-RADIATION, Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
General Guidance Before returning the receiver to the customer,
An Isolation Transformer should always be used during always perform an AC leakage current check on the
the servicing of a receiver whose chassis is not isolated from exposed metallic parts of the cabinet, such as antennas,

When replacing a high wattage resistor (Oxide Metal Film measured resistance should be between 1M and 5.2M.
Resistor, over 1W), keep the resistor 10mm away from PCB. When the exposed metal has no return path to the chassis the
reading must be infinite.
Keep wires away from high voltage or high temperature parts. An other abnormality exists that must be corrected before the
receiver is returned to the customer.
Due to high vacuum and large surface area of picture tube,
extreme care should be used in handling the Picture Tube. Leakage Current Hot Check (See below Figure)
Do not lift the Picture tube by it's Neck. Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check.
X-RAY Radiation Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor
between a known good earth ground (Water Pipe, Conduit, etc.)

Measure the AC voltage across the resistor using AC
The source of X-RAY RADIATION in this TV receiver is the voltmeter with 1000 ohms/volt or more sensitivity.

For continued X-RAY RADIATION protection, the voltage measurements for each exposed metallic part. Any
replacement tube must be the same type tube as specified in voltage measured must not exceed 0.75 volt RMS which is

In case any measurement is out of the limits specified, there is
possibility of shock hazard and the set must be checked and
repaired before it is returned to the customer.
To determine the presence of high voltage, use an accurate
