Page 3: Safety Precautions
Safety Precautions Turn on the receiver’s power switch. General Guide Lines power-on It is advisable to insert an isolation transformer in the AC supply before servicing a hot chassis. Isolation Transformer Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the receiver, such as screw heads, aerials, connectors, control shafts, etc.
Page 4 X-Radiation Warning: The potential sources of X-Radiation in TV sets are the High Voltage section and the picture tube. When using a picture tube test jig for service, ensure 33.0kV that jig is capable of handling without causing X- Radiation. Note: It is important to use an accurate periodically cali- brated high voltage meter.
Page 5: In Regard To The Self-Check Function
In regard to the self-check function When phenomena like “the power fails from time to time” or “the video/audio fails from time to time” can not be confirmed at the time of servicing, the self-check function can be used to confirm the occurrence and to limit the scope for the defective circuits. Also, when “the power fails from time to time”, display of the color bar on the screen can be used confirm the occurrence and to limit the scope for the defective circuits.
