SAFETY
RELATED
COMPONENT
WARNING
!!
Components identified by shading and {\ marked on the
schematic
diagrams
and
parts
list
are
critical
to
safe
opera-
tion. Replace these components with SONY parts whose part
numbers appear as shown in this manual of in supplements
published by SONY. |
SAFETY CHECK-OUT
After correcting the original service problem, perform the
following
safety
checks
before
releasing
the
set
to
the
customer
:
Check
the
metal
trim,
“metallized
”
knobs,
screws,
and
all
other
exposed
metal
parts
for
AC
leakage.Check
leakage
as
described
below.
LEAKAGE TEST
The
AC
leakage
from
any
exposed
metal
part
to
earth
ground
and
from
all
exposed
metal
parts
to
any
exposed
metal
part
having
a
return
to
chassis,
must
not
exceed
0.5
mA
(5OO
microampers).
Leakage
current
can
be
measured
by
any
one
of
three
methods.
1.
A
commercial
leakage
tester,
such
as
the
Simpson
229
or
RCA
WT-540A.
Follow
the
manufacturers
instructions
to
use
these
instruments.
2.
A
battery-operated
AC
milliammeter.
The
Data
Precision
245
digital
multimeter
is
suitable
for
this
job.
3.
Measuring
the
voltage
drop
across
a
resistor
by
means
of
a
VOM
or
battery-operated
AC
voltmeter.
The
“limit”
indi-
cation
is
0.75V,
so
analog
meters
must
have
an
acturate
low-voltage
scale.
The
Simpson
250
and
Sanwa
SH-63Trd
are
examples
of
a
passive
VOM
that
is
suitable.
Nealy
all
battery
operated
digital
multimeters
that
have
a
2V
AC
range
are
suitable.

Power supply
e The unit is designed for operation on a power supply
meeting the requirements indicated in the
“Specifications” on page 9.
e Do not drop or place heavy objects on the power cord. If
the power cord is damaged, turn off the power
immediately. It is dangerous to use the unit with a
damaged power cord.
e Disconnect the power cord from the AC outlet by
grasping the plug, not by pulling the cord.
Keep foreign objects out of the cabinet
Dropping flammable or metal objects into the cabinet, or
spilling liquids nearly can lead to accidents.

OPERATION DESCRIPTION
2-1. POWER SUPPLY OPERATION DESCRIPTION
120 V AC (CMA-D2) or 100 to 240 V AC (CMA-D2CE) is
rectified by the bridge diode (BRI) and smoothed by the
electrolytic capacitor (C6). |
And it 1s switched by the transistor (Ql), transformed by the
transformer (T1), rectified by the diode (D51) and smoothed by
the electrolytic capacitors (C51, C52), and it goes cut.
The shunt regulator (IC51) detects its output and it is fed back by
the photocoupler (PC1).
So the output voltage is regulated.
This power supply has the overcurrent protector and the
overvoltage protector for output.
The overcurrent protector controls the output current by detecting
the primary current when the output is in the overcurrent state.
The overvoltage protector is using the zener diode (ZD51) at the
output.
