Did you ever get this problem sorted out? I have the same TV, and almost identical issues with the video - it loos just like your picture. No clear picture or image on any input. Unable to see the menu.
Every once in a while, the image will look absolutely perfect for a split second, and then back to ugly.
Have you repaired this TV? If yes, please tell what you did to fix it, or what board you replaced that solved the problem.
I'm also having the same issue and would also like to know if you solved the issue. I checked on Ebay for the boards and total is over $170 for all of them. Not sure if I should buy the boards or put the money towards another TV.
