Sorry if this is the wrong forum, I wasn't really sure which one to use. I keep getting these colored lines (black and grey during Battlefield 3, and black and purple during SSX) flashing across my screen when I play games. They go over the terrain, and seem to be more prominent in well lit areas. I have an HDMI hookup that I use, and I use the same cable to connect my cable box to the tv, and I don't have any issues with that. Does anyone know why this is happening, and how I can fix it?
