I had it picked up to be fixed on warranty. Downside is I'm out a TV for a week.

In all the time that you have had the tv have you applied 2 firmware updates that some of the tv's need to avoid other known issues with the lcd in the future. These firmware updates are for the main cpu PH1UU112 and the monitor MD1UA104. I don't know if this is the case for you but it worked for me. Call Sharp at 1-800-237-4277.
