Connect external power supply PS1 to #3, external power supply PS2 to TP7, and set PS2 to 0 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 #43 picture period voltage VLDGOFF2 [V].
Set light area static Y γ gain [1C] to MAX [14], PS1 to VLGP [V], measure #43 picture period voltage
VlSGMAX, and calculate GLASGMAX [dB] using the following equations.
Set light area static Y γ gain [1C] to MIN [16], PS1 to VLGP [V], measure #43 picture period voltage
VLSGMIN, and calculate GLASGMIN [dB] using the following equations.
