• Go to Settings —> General —> Eco Solution and make sure Ambient Light Detection is disabled, Power Saving Mode is off, and Motion Lighting is off. Then go to Settings —> Picture —> Expert Settings and make sure Backlight is at least 14 or so and Contrast at least 90. Brightness should be 0. Check Auto Motion Plus Settings and make sure LED Clear Motion is turned off. You might also try setting Gamma to 1. Finally, under Settings —> General —> External Device Manager, if HDMI Black Level is Auto or Normal, try setting it to Low.

• Open settings, then general, then Eco Solution. Disable everything.
