Checks OUT
T
erminal 5V output of REG IC1000 or
,
c
hecks GND and OUT
T
erminal with
Tester
.
Is it shorted out?
Assembles into the unit again then, checks
whether there is the audio output from
DAMP Board.
Checks circumference circuit of REG IC1000.
If there are no problems, exchanges IC1000.
Checks circumference circuit of REG IC1001.
If there are no problems, exchanges IC1001.
