I did a bunch of research on this last night. For this particular problem/make it is on the power supply board, just crappy cap's I think. The screen problems seem to be across the board, when it dies it dies. 50,000 hours is what most say. I don't believe it, from what I read last night. A lot of Fella's like Me on Geek sites, trying to come up with a fix. Nice thing is it's easy to get to things, and it works, for the most part like the old TV's.
The 3D is not for Me, I get bad headaches.
