Vs, Va VOLTAGE ADJUSMENT
Preparation:
Turn on the set and perform pre-heat run more than 1 minute with a snow noise screen. Receive full black pattern (blanking level) signal (or Video No signal; in this case, it will be automatically turned off after a few seconds because of power save function). Connect voltmeter leads to the Vs or Va and GND test points on power unit.
- Turn Vs ADJ to adjust Vs voltage to be within 0.1V of the value specified in the label on the panel.
- Turn Va ADJ to adjust Vs voltage to be within 0.2V of the value specified in the label on the panel
- Reconfirm that Vs voltage remains within 0.1V of the value. Readjust if It's outside the margin.
