I have this rear projection that won't accept a signal from the remote, or any remote for that matter. I've tried resetting and powering down, the remote that came with the TV works fine with the cable box but the picture is stuck on standard, so i can't see anything on wide screen. How do i fix this? I've tried the 800 number but no help. I like the TV fine so it would be a tragedy to have to get rid of it. Please help!
