I have an LN52A550 that I bought off of craigslist. The problem lies either with the panel or the tab bonds, but I don't have enough experience to figure it out. What began as just a band of colored lines across the screen has turned into those same colored lines, but now that entire half of the screen is black.
I have tried the tab bond repair methods mentioned throughout these forums, but I haven't had any success with them. I have also replaced the T con board, and it did not change anything.
On startup, the lines are visible while the rest of the screen is still black. The menu does not override the lines, and all functions of the screen on the right side are BEHIND the lines/black screen.
I've attached pictures, but the lines are hard to see in them. They are right next to the halfway mark on the screen - where the picture works. The black screen image is right after startup, before the picture is on, and the colored lines are still visible.
