Re: images go suddenly darker
Turn off the the OPC feature in the Menu. If that doesnt help, what youre seeing is most likely the Advanced Dynamic Contrast going to work. In layman's terms, it automatically adjusts the contrast depending on the video signal it is receiving. If you want to disable this, change the AV settings to "User" (button underneath the bottom door on the sharp remote)

You can make several adjustments to improve your images such as lightening dark areas, changing the exposure, sharpening blurred edges, and changing the brightness and contrast.
Exposure adjusts the overall intensity of light in an image.
Adaptive Lighting improves only the dark areas in an image without affecting the bright areas.
Brightness adjusts the amount of light in colors ranging from light to dark.
Contrast adjusts the difference in brightness between light and dark areas of an image.
Sharpness helps define edges and the smoothness of texture in an image. Use this tool to make a blurred image appear more focused.
