Item
Vs and Va VOLTAGE ADJUSTMENT
Applicable Model
55PMA550 , 55HDM71
Preparation
Procedure
(1) Keep heat-run for 1 minutes or more.
(1) If the difference between the printed voltage of Vs
and the indicated value of Vs Voltmeter is over
0.1V, adjust the Vs ADJ VR located on the Power
Supply Unit to make it within 0.1V.
(2) Connect the DC Voltmeter to the Vs test point
and the GND point (or the Va test point and the
GND point) on the Power Supply Unit.
(2) If the difference between the printed voltage of Va
and the indicated value of Va Voltmeter is over
0.2V, adjust the Va ADJ VR located on the Power
Supply Unit to make it within 0.2V.
(3) Receive the all black signal with no setup.
(3) Check and do the procedure (1) again.
(4) Check the indication of Vs and Va voltages
printed on the label located upper left side on
the Panel Module.
