is
to
prevent the power IC

Accordingly,
if

upon

• BEFORE STARTING THE REPAIRING
Before adjusting or repairing,
be
sure
to
short-circuit
opposite poles
of
the
8200pF
capacitors (C501, 502)
with
a
resistor
approximately
of
"50[2,
5W"
for
discharging the
charged voltage .
Short-circuiting
with
a screw driver and the like
is
not
only
dangerous, but may destroy transistors
and
diodes,
and
should therefore
be
avoided.
• HOW
TO
REMOVE THE POWER IC
1.
Remove the solder
of
power
IC
for
both
Lch
and Rch.
2. Remove the 3 setscrews
(CD
-®
in
Fig.
5)
use
to
fasten the heat sink
from
the center bracket.
3.
Remove the heat sink along
with
power IC in
the
direction
of
arrow G (Fig.
6)
4.
Remove the 2 setscrews
(@,
CID
in Fig.
6)
used
to
secure the power
IC
on the heat sink,
and
then pull the power IC in
the
direction
of
arrow
@.
5.
When
mounting
the power IC,
apply
silicone
compound
(or equivalent heat diffuser)
to
the
back
of
power I
C,
and then
follow
the steps 1
- 4 reversely.
