Well I took it apart, and there were three connectors that were barely connected. Also, on one of the ribbon cables near the bottom, there was, what looked like, a piece of clear plastic that looked like it wedged itself between the ribbon sections (4 little sections of ribbon). I pulled that out, reset all the connections (staying away from any re: the power source) and then cleaned everything up. The picture below shows where the plastic piece was wedged, but I had already removed it.
The only thing I noticed that looked odd, was on the board on the left hand side (when looking into the back of the TV). As you can see, around what looks like thermal paste on the sqaure pieces.
Not sure what those white areas are, maybe just dried glue etc., but I did not notice anything else odd, other than the clear plastic piece I removed from the ribbon section and the loose connectors.
So far it is working, but that doesn't mean much. One thing I will note, when they replaced the panel they said I was getting a new one, and I would have demanded as much. The paperwork even says new panel, yet the panel I have clearly says refurbished on it. While this is probably within warranty parameters, I find it pretty freaking annoying I was told it would be new, because I would have never accepted a refurbished panel on a warranty issue. I paid new panel price and would expect a new panel replacement. But again, this is more me venting than anything haha!
