Part 6: Electrical Diagrams 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. Capacitor Reading Example 2000 K K 1000 BG q Material table Example 160 E M 10 Characteristic Capacitance value Excepting electric capacitors, all capacitance values of less than 1 are expressed in µF and more than 1 are in pF.
