I'm very sorry for any inconvenience this may have caused you. While I get the general impression from your post that you want help figuring out how to self repair, I figured I'd offer to setup service with an authorized service center, if you'd like for me to. Here's the thread where you can get details on contacting us: http://forums.cnet.com/7723-13973_102-542437/service-issues-click-here-for-help/
I have a Samsung LN52A580P6FXZA TV bought 3.5 years ago. Recently a 6 inches blue vertical bar shows up in the middle of the TV. It is there even with the blue ray player. Called Samsung support but they couldn't help me because it is out of warranty. Anyone know the problem and how to fix it? Thanks.
