Hi All, I was watching a recorded program, and it ended while I was in the other room. Sometimes I just let the receiver "time out" and it will go back to live TV. Well I noticed that no audio came back on after a long time. I went to look and saw Searching for Satellite Signal 771 error on the screen. I was on channel 4 (NBC). I thought possibly bad weather, but changed to 231 and that was on and working fine. The only channels that are out are the "Big 4" (2 - ABC, 4 - NBC, 5 - CBS and 17 - Fox). MyTv, WB, PBS and 22 (ind) all come in fine. I checked on all the receivers and they are out of all of them. I checked the signals and all were in the mid 90's like normal. I restarted one receiver and still they are out. Is anyone else having the same issue? Also what transponders are these channels on? Thanks Michael.
