BEFORE
REPAIR
AND
ADJUSTMENT
(1)
Turn
off
the
power
supply.
Using
a
109,
10W
resistor,
shortcircuit
both
ends
of
power
supply
capacitors
(C705,C706)in
order
to
discharge
the
voltage.
(2)
Before
turning
on
the
power
switch
of
the
unit.
A.
Connect
the
voltage
controller
to
the
primary
side.
B.
Connect
the
AC
ampere
meter
to
the
primary
side
or
connect
the
DC
voltage
meter
to
the
“+B”
circuit
of
the
secondary
side.
C.
Turn
the
VR
of
ICQ
(VR451
and
VR452)
to
minimum
(counterclockwise).
D.
After
setting
the
output
to
zero
of
the
voltage
contoller,turn
on
the
power
switch
of
the
unit.
And
increase
the
output
of
voltage
controller
gradually.
Then,
check
carefully
whether
the
current
value
of
primary
side
become
more
than
following
value
or
whether
the
DC
voltage
of
secondary
side
is
increasing
slowly.
E.
If
the
value
of
current
is
increasing
unusually
or
the
DC
voltage
is
not
increasing,lower
the
output
level
of
voltage
contoller
immediately.
@
The
current
value
of
the
primary
side
at
no
signal.
(Confirm
the
power
supply
voltage
of
each
area
and
provided
voltage
of
the
unit.)
