pin (1) of IC3105?

Yes

Check the VIDEO-IN signal

line of C3503.

Is input coming to pins (1), (3) and (5) of IC3104?

Yes

Check IC3102 peripheral circuits.

Is output coming from pins (16), (18) and (20) of IC3104?

Yes

Check IC3104 peripheral circuits.

Is the picture signal inputted to pins (43), (48) and (54) of

IC6004 and the synchronized signal inputted to pins (30)

and (31)?

Yes

Check around IC3104, IC6001 and IC6002.

Is each digital output coming on pins (64), (65), (66) and

(67) of IC6004?

coming to pins (28) and

(29) of IC3102?

Memo

The composite video signal is Y/C-separated by IC3506 (3 Line

COM) and the resulting signals are inputted to pins (39) and

(41) of IC3105.

The video signal is outputted from color-difference pins (21),

(22) and (23) of IC3105.

Are the video signals inputted to

pins (39) and (41) of IC3501?

Yes

Are the video signals outputted

from pins (21), (22) and (23) of

IC3501 and inputted to pins (67),

(68) and (69) of IC3102?

Check IC3504, IC3506 and

their peripheral circuits.
