The service Precaution:
The area enclosed by this line
( ) is directly 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.
Product safety notice:
Product safety should be considered
when a component replacement is
made in any area of a receiver.
Components indicated by a mark /!\
in this circuit diagram show compo-
nents whose values have special
significance to product safety. It is
particularly recommended that only
parts specified on the part service
manual be used for components
replacement pointed out by the
mark.
Circuit diagram notes :
1. All resistance values are in ohms, K=1,000, M=1,000,000.
2. All resistance rated wattages are 1/6W unless otherwise
noted.
3. Excepting electrolytic capacitors, all capacitance values of
less than 1 are expressed in µF and more than 1 are pF.
4. All capacitance rated voltages are 50V unless otherwise
noted.
5. All inductance values are in µH.
6. Voltage readings taken a digital voltmeter are from point
indicated chassis ground. Voltage readings taken by using
a colour bar signal are with all controls at normal position.
Some voltages may vary with signal strength.
7. Waveforms were taken with colour bar and controls
adjusted for normal picture. Waveforms were taken by
using a wide band oscilloscope and a low capacity probe.
8. This circuit diagram covers a basic or
representative chassis only. There
may be some components or partial
circuit differences between the actual
chassis and the circuit diagram.
9.■ Diode 1S1555 may be replaced with
1S2473,1S2076 or DS472 unless
otherwise noted.
■ Transistor 2SC536(Q,R,S),
2SC1740(Q,R,S), 2SC945A(Q,R,P)
or 2SC1815(G,O,Y) unless other-
wise noted.
■ Transistor 2SA608(E,F) may be
replaced with 2SA933(Q,R),
2SA564(QA,RA), or 2SA1015(O,Y)
unless otherwise noted.
