I was watching tv on food network when all of a sudden I got a screen saying acquiring signal. It had the test and went 1 of 5 2 0f 5, and so on. Then it would start over again. I checked other tvs, we have a 2nd tv running off the dvr upstairs and it was working fine. But the tv1 with the reciever said acquiring signal. Also our hdtv reciever is working fine. I don't understand what could be the problem. I called the support and said they would send someone out monday. Any one know of this problem?
