I have two 811 receivers and a 322 in my setup. I sat down to watch the game on NFL Network Thurs night on the 811 in my home office and I get the no sat signal screen and it just sits there, not going through the motions to acquire signal or anything. I tried flipping through the channels and most come in fine, but several give me the same response, I try NFL Network on both TV's hooked up to the 322 and there is no problem, then I try it on my other 811 and it comes in fine there too. I just let it go figuring the receiver was being glitchy, then tonight I sit down to watch the Heat game on Sun and I go through the same thing. Nothing has been changed as far as the hookup of the receiver or the outside wiring from Sats to switch, so why would the receiver just not pick up these channels when two days ago it was working fine? Any help or comments would be appreciated.
