I accidently leaned on the controller while wrestling with the dog. When I looked up I saw that the screen has blacked out in the center but there is still a 1/2" of picture around the outer edge and good sound. I went through the menu and video adjustments, caption locks, owners manual etc but no luck. I am connected to a satalite and have a second TV split off from this one and it works fine leading me to believe the controller was likely on the "TV" mode when I screwed it up. Would anyone have an idea as to what the problem is?
