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)
