Parts Description And Reading In Schematic Diagram - Sanyo PDG-DXL2000 Service Manual

Parts description and reading in schematic diagram

1. T he parts specification of resistors, capacitors and
coils are expressed in designated code. Please check
the parts description by the following code table.
2. S ome 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. V oltages and waveforms were taken with a video
color bar signal (1Vp-p at 75 ohms terminated) and
controls to normal.
4. V oltages were taken with a high-impedance digital
voltmeter.
