Description of Schematic Diagram

Safety note:

1. Disconnect the AC plug from the AC outlet before

replacing parts.

2. Semiconductor heat sinks should be regarded

as potential shock hazards when the chassis is

operating.

Important safety note:

Parts marked with «

for maintaining the safety of the set. Be sure to

replace these parts with specified ones for

maintaining the safety and performance of the set.

WAVEFORMS

Note:

1. The unit of resistance «ohm»is omitted (K=1000 ohms.

M= Megaohm).

2. All resistors are 1/16 watt. unless otherwise noted.

3. All capacitors are µF, unless otherwise noted (P= µµF).

4. The capacitor with Part No. RC-FZ9XXXBMNJ is

designed to with stand 63V.

5. The capacitor with Part No. RC-FZ4XXXBMNJ is

designed to with stand 50V.

Service precaution:

The area enclosed by this line is directly (

connected with AC mains voltage.

When servicing the area, connect an insolating

transformer between TV receiver and AC line to

eliminate hazard of electric shock.

Waveform measurement condition:

Colour bar genetator signal of 70 dB from RF input.
