Yeah I went through a bunch of them and had Comcast come out every week for like 2 months, they would change it out and same thing. I finally went directly to the TV and it stopped. When I got a newer box I changed it back and now it doesn't drop out on that input but the Xbox gives a fault that says it's the AV receiver when I try to play a disc, haven't had time to fool with it and see if a game actually plays haven't turned it on in 2 years. lol
