2. Adjustment of +64V
(1) Using any video signal of VIDEO input, DVD/HD input, or RGB input, and display a color bar signal. Turn on
the power switch of the main unit.
(2) Confirm that the voltage at TP4 (D+60V output) and TP2 (D.GND) of the power unit is maintained at a
voltage value (Vd value of the label described in Item 1 above) within ± 1V, specified for the PDP module.
If the voltage specified above cannot be secured, turn the volume control (RV4) in the [D+64V ADJ] block
and adjust the voltage until it attains "the voltage specified for the PDP module (Value Vd on the label of the
above-mentioned Item 1) ± 1V."
3. Adjustment of +5V
(1) Use any video signal of VIDEO input, DVD/HD input, or RGB input, and display a color bar signal.
(2) Confirm that the voltage value between TP1 (+5V output) and TP2 (D.GND) of the power unit is maintained
at "5.10 ± 0.1V."
If the voltage specified above cannot be secured, turn the volume control (RV2) in the [D+5V ADJ] block
and adjust the voltage until it attains "5.10 ± 0.1V."
