Not sure if EZ setup is equipped in this Sharp Model but try to switch to TV Mode and select the EZ SETUP from the option menu. When you get to the TV LOCATION option select HOME.
Also, look for a reset option in the picture mode.
Hope this helps.
WONDERFUL...my remote has an AV MODE and that worked......what is AV mode???
The AV Mode option contains a few preset picture settings used for different video sources. The default setting is 'DYNAMIC(Fixed)' which looks far too saturated and grainy. Standard seems to be best while watching Blu-rays and "Game" looks better with HD Game Consoles such as the PS3 or Xbox.
