I just picked up a Samsung 61 inch DLP TV. I have all of my systems (Cable box, 360, Wii, PS2) hooked up threw an HD Pelican Component switch box.
Here is where the craziness happens. When the cable box is plugged in to my switch box everything gets a green line and a purple line moving horizontally across the screen. This includes the 360, Wii, and PS2. The second I unplug the cable box video cables from the switch box everything is fine. What I can't figure out is I had this same setup before I got the DLP and everything worked great.
I removed the cable box from the component switch box and plugged it into the second component port on the television it self and am still getting the lines, but now much much fainter the before.
If anyone has any ideas please help me out. I have been consumed with this problem all day.
