My Sony LED TV KDL46EX525 has white screen

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.
Request for quick help!    :sign0085:

Looks like a T-con problem to me. I'd say the AS15 IC on the T-con, but I can't be sure if it uses this IC.

 Dear! At the beginning, my TV has a Sony logo. After that briefly has a normal picture and then the display becomes milky white with these letters and numbers in up from the display TV has white screen with letters -  top , left s written : TMP and top right s written :TIM .   T-con is OK !
 TV works in agieng mode. I can not do a factory reset. Also, I can not enter Service mode.

Regrettably I have no idea what said writing means, nor can I find any reference to it - secret Sony business perhaps. I'm as confused as you are.

After talking to a Sony service technician, the appliance is placed in the factory test option, and the return from the service is not possible with the service remote.Only one solution-replace mother board.
