create shock, fire, X-RAY RADIATION or other hazards.
GENERAL ADJUSTMENT
AUTOMATIC DEGAUSSING
An automatic degaussing coil is attached around the picture tube, degaussing the tube
properly in about one second after the set is switched on. If the receiver is moved or
faced on a different direction, the power must be switched off at least 15 minutes in
order that the automatic degaussing circuit operated properly. External degaussing is
necessary if the automatic degassing proves ineffective after the set is moved.
B+ ADJUSTMENT
C
AUTION: To avoid X-ray hazards and result in a nominal display width, B+ voltage
must be set in the scale of 108.0V+/-0.5V.
1.
Make sure the AC power supply is 230V, 50Hz.
2.
Switch on the TV receiver, tune in an active channel.
3.
Measure the voltage between C641 on Main P.C. Board by DC voltmeter.
4.
Set contrast, brightness, color to maximum.
5.
Adjust VR631 on Main P. C. Board for B+108.0V+/-0.5V voltage reading.
