A couple of days ago my tv turned off by itself and when I tried to turn it back on the power light just flashed. Eventually it came back on and had some color issues on the right side of the panel. That also went away. Now I have about a 2 to 3" vertical black bar on the right side of the screen. The tv is out of warranty. I did some googling and found that it might be a user replaceable part but I do want to get some more confirmation on what that part is and how to install it.
