This TV set has a built-in power supply protection circuit.
It is provided to protect the TV set in case of a power supply circuit malfunctions. When something abnormality
occurs during TV reception, the TV set goes to the stand-by mode.
When an abnormality occurs during TV reception, it causes pin 33 of the CPU to go continually Low(less than
0.75V) for about one second. The CPU detects that this has occurred and outputs the signal from pin 8 to
switch off the power supply lines.
Releasing the protective circuit and restoring power supply
To release the protective circuit and restore power supply, turn the power to theTV set OFF and then ON again
via either the main power switch or the ON-OFF button on the remote control.This will work only if the power
supply trouble was temporary. If there is permanent trouble such as a damaged circuit, power cannot be
restored and the circuit will have to be repaired.

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 NOTICE:
1. All resistance value 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 µ F and more than 1 are pF.
4. All capacitance rated voltages are 50V unless otherwise noted.
5. All inductance values are in µ H.
6.Voltage readings take with a "VTVM" are from point indicated chassis
ground.Voltage readings taken by using PAL colour bar signal are
with all controls at normal position. Some voltage may vary with signal
strength.
7.Waveform were taken with PAL colour bar and controls adjusted for
normal picture. Waveforms were taken by using a wide band oscillo-
scope 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. Parts specified with "X" are not installed in this model.
10. Parts specified with "J" are just jumper wires.
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.
11. Expression of capacitance and resistance in circuit diagrme.
