DESCRIPTION OF SCHEMATIC DIAGRAM
NOTE:
1.
The unit of resistance “ohm
x
is omitted
(K
= 1000 ohms,
M
=
Meg ohm).
2.
All
resistors are
l/8
watt, unless otherwise noted.
3.
A/I
capacitors are
pF.,
unless otherwise noted P
=L#
4.
The diodes, whose parts code is not described, are the
lSSll9.
5.
All resistors are
118
W,
unless otherwise noted.
VOLTAGE MEASUREMENT CONDITIONS:
1.
Voltages without parenthesis measured with
3000
@I
B & W
or Color Signal.
2.
The voltage in parenthesis represents the value measured
with no signal.
3.
All the voltages were measured by using a high impedance
voltmeter.
WAVEFORM MEASUREMENT CONDITIONS:
1.
The co/our bar signal applied to the TP40 1 is 1
.BVp-p.
2.
The tuner AGC voltage is approximately 4V.
SAFETY NOTE:
1.
DISCONNECT THE AC PLUG FROM THE AC OUTLET BEFORE
REPLACEINC
PARTS.
2. SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS
POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS
OPERATING.
SURE TO
REPLACE THESE PARTS WITH SPECIFIED
ONES FOR
SERVICE PRECAUTION:
The area enclosed by this line
(
-
I
-
)
is direct/y connected
with AC Mains Voltage.
When servicing the area, connect an isolating transformer
between TV receiver and AC line to eliminate hazard of
electric shock.
