1. PARTS DESCRIPTION AND READING IN SCHEMATIC DIAGRAM
1. The parts specification of resistors, capacitors and coils are expressed in designated
code. Please check the parts description by the following code table.
2. Some of transistors and diodes are indicated in mark for the substitution of parts
name. Please check the parts name by the following code table.
3. Voltages and waveforms were taken with a video color bar signal (1Vp-p at 75 ohms
terminated) and controls to normal.
4. Voltages were taken with a high-impedance digital voltmeter.
