TROUBLE SHOOTING TABLE
If there is no signal at SC1501
and SC1502, go to the video
system block.
Checking the output PWB unit
No
If there is no signal at SC1404
and SC1405, go to "Trouble
shooting table for PC I/F unit".
No
If there is no signal input at
pins (1) and (31) of SC1101,
SC1102 and SC1103, check
the switching circuit and
amplifier circuit of IC1101,
IC1201, IC1301, IC1102,
IC1202, IC1302 and their
peripheral circuits.
