Yes
Checking the output PWB unit
Are there signal inputs at
SC8405, SC8502, SC8404?
Are voltages applied to EA
connectors?
Yes
No
No
No
Check IC1401,Q1401,Q1402,
Q1403 and their peripheral
circuits.
Are there signal outputs at
pins (18) (16) (14) of IC1401?
Yes
No
Are there signal inputs at
pin(44) and (47) of IC1101,
IC1102, IC1201, IC1202,
IC1301 and IC1302?
Yes
No
Check IC1101,IC1201,IC1301
and their peripheral circuits.
Are there signal outputs at pins
(17), (19), (21), (28), (30) and
(32) of IC1101, IC1102,
IC1201, IC1202, IC1301 and
IC1302?
Yes
Yes
No
If there is no signal input at
pins (15) and (30) of
SC1101, SC1102 and
SC1103, check IC1001,
IC1004 and their
peripheral circuits.
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.
Are there signal inputs at
SC1101, SC1201 and
SC1301?
Check IC1558, IC1559,
IC1551~IC1556 and their
peripheral circuits.
Check the R, G and B panels.
If there is no signal at EA
connector or SC8404, SC8405
and SC8502, go to Checking
the power unitblock.
If there is no signal at P4302,
P4303 and P4301, go to
"Checking the video system".
Check IC2102, IC2202,
IC2302 and their peripheral
circuits.
