OPEN 1. Connect external power supply PS1 to #68, external power supply PS2 to TP1, and set PS2 to 0 V.
2. Set dark area dynamic Y γ gain [1C] to MIN [03], and dark area static Y γ gain [1C] to OFF [03].
3. Set PS1 to V
4. Set PS1 to VDGP [V], and measure #12 picture period voltage VSGOFF2 [V].
5. Set dark area static Y γ gain [1C] to MAX [1F], PS1 to VDGP [V], measure #12 picture period voltage
6. Set dark area static Y γ gain [1C] to MIN [07], PS1 to VDGP [V], measure #12 picture period voltage VSGMIN,
VSGMAX, and calculate GDSGMAX using the following equations.
and calculate GDSGMIN using the following equation.
