My HR23-700 has recently started putting lines across my display when using component or composite, not hdmi. It does this all the way from the start screen even without the swm lines connected from the dish. I have tried it on multiple tv's with multiple cables, no issues with my other box, but when I hook this one up the lines are there. Can my component/composite video card just be broke? Does anyone else have this issue or any fix? Or do I have to get a new box?
