My Sony LED TV : KDL46EX525 has white screen with top left TMP = 29 and top right TIM = 0. I can do what I want, press any key, wait after switching off, I keep coming back to the white screen. If I take the power and wait 60 s, comes first briefly the last set channel (with a bit too bright picture) and then the white screen again. Please see photo in attashment. I tried to do a factory reset, but it can not .Does my LED TV Sony have the software problem? How will I get out of this? For the recovery software and the manual, I would be really grateful.
