Quick check shorted components 2
Without any extension cable, quick measure the Q1101/1102 and 14 power
output MOSFETs; also measure the +/- 7V to determine if it is shorted.

Measure the
resistance, if
less than 100
Ohms it’s NG.
For Example: If
the resistance
between +B (-B)
and AMP_+B
(AMP_-B) is
less than 100
Ohms the
Q1101 (Q1102)
is shorted.
See next slide
to know the
measure points
on schematic
for all of other
components.
