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 components 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 otherwise
noted.
■ Transistor 2SA608(E,F) may be replaced with
2SA933(Q,R), 2SA564(QA,RA), or 2SA1015(O,Y)
unless otherwise noted.
