I had a similar problem and I believe the problem is with the high voltage circuit and ccfl transformers. If you know electronics you may be able to find the chips that provide the power input to the CCFL transformer (I had two transformers and 4 FET's). You will also need a micro soldering station and excellent soldering skills to replace the flat packs (SMT). Hope this helps.

Unplug the TV for about an hour to see if it will reset itself, if not, try:

TV stops responding to controls:
If the TV stops responding to the controls on the remote
control or TV control panel and you cannot turn off the

panel for 5 or more seconds to reset the TV.

Reset Factory Defaults

default values:
Press and open the Setup menu.

Enter your PIN code (or 0000 if no PIN code has been set).
Highlight Yes and press . The TV will turn off
automatically after a few seconds. After the TV turns off,
