I am no expert but am experiencing the same problem. I have taken it to the repair shop and he said the main board is faulty. Looking around the forums, this seems to be a common problem with these TVs. I am trying to find how expensive the board will be to replace it but I'm not holding my breath. I will keep you posted.
