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.
