Connect external power supply PS1 to #68, external power supply PS2 to TP7, and set PS2 to 1.2 V.
Set dark area static Y γ gain [1C] to 0dB [17], and light area static Y γ gain [1C] to 0dB [17].
Set PS1 to V
Set PS1 to VLGP [V], and measure #12 picture period voltage VLDGOFF2.
Set light area static Y γ gain [1C] to MAX [14], PS2 to 0 V, PS1 to VLGP [V], determine #12 picture period
voltage VLDGMAX [V] using the following equations.
