Is there signal input at
NoNo
SC6801?
Are voltages applied to EA
connectors and SC8404,
If there is no signal at EA
If there is no signal at SC8404 SC8405 and SC8502?If there is no signal at SC6801, connector or SC8404, SC8405
and SC8405, go to "Trouble
go to the video system block. and SC8502, go to Checking
shooting table for PC I/F unit".Yes
the power unitblock.
Are there signal outputs at
Nopins (17) of IC2101, IC2102,
IC2201, IC2202, IC2301,
IC2302?
Check IC2101, IC2102,
Yes
IC2201, IC2202, IC2301,
IC2302 and their peripheral
circuits.
Are there signal inputs at pin No
