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.
