Service Adjustments

Service Adjustment-4

1. Receive the monochrome circular pattern.
2. Set the brightness to normal and contrast to maximum.
3. Adjust the focus control on the F.B.T. for the best focus

on the screen centre.

FOCUS ADJUSTMENT

FOCUS VR (Upper side)

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 27 of the CPU to go continually Low volt-
age for about one second. The CPU detects that this
has occurred and outputs the signal from pin 31 to
switch off the power supply lines.

Releasing the protective circuit and restor-
ing power supply

To release the protective circuit and restore power supply,
turn the power to the TV 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 trou-
ble was temporary. If there is permanent trouble such as a
damaged circuit, power cannot be restored and the circuit
will have to be repaired.

Protection Circuit

1. Connect a DC voltmetre to J110 and the ground.

Set the +B adjustment control (VR651) to middle range.

2. Set the brightness to normal and contrast to maximum.
3. Tune the receiver to an active channel and synchro-

nized picture.

4. B voltage to 140± 1.0 volt DC by using VR651.

+B POWER SUPPLY ADJUSTMENT

VR651

J110

MAIN BOARD

Note: +B (+140V) Voltage and Grayscale Adjustment must be

completed before attempting High Voltage Check.

1. Connect high voltage voltmeter negative lead to 

ground, and c lead to anode of picture tube.

2. Tune receiver to an active channel and confirm TV is 

operating properly.

3. The high voltage must be 29.5KV ± 1.5KV and less than

32KV at 0 beam current (Brightness and contrast 
minimum setting).

Note: If the picture tube is replaced, check the high 

voltage.
