■ Parts description and reading in schematic diagram

ME3-XU4500, MF3-XU4600

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.
