I hope someone here can help me. I am getting 5 vertical lines when I watch tv in the 480i format. It works fine when I'm in the 1080 format (dvd's and hd). I had a tech out here today and basically had to show him it didn't have anything to do with the cable...the guy was clueless!! Any help would be much appreciated even if it's just a referral to a tech you might of used and were satisfied with. I live in Orange County CA...Thanks
