Hi. I've had my set for about 1.5 years and last night I noticed that there is a 'tree branch' shape line in the middle of the screen that goes from the top to about half way the screen. The line is green in color and it's flasing really fast. It is mainly visible in dark scenes or when you changed the channel when the screen goes dark for a secon. I tried to disconnect my DVD player, Directv box, and Receiver but it's still there. I tried to switch to different video inputs (video 1, 2, etc.) and it's still there. I googled the kf-60we610 and found several people having problems with what they call a 'grid lines' or 'road map' that looks like it's fixed to the screen. The problem I'm having is different though. The line (green in color) flickers or flashes really fast, kinda like when lightning strikes but continously and really fast. Anybody had this problem before. Any help would be appreciated. Thank you.
