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.
