Hi all – This is my first time posting, so I apologize for any details that I may leave out. I currently have a DirecTV dish (not sure exactly on make) connected to my house through a SWM system with currently 2 HD receivers (one the HR24) and 1 standard receiver. This past weekend everything with my system was fine. Last night, however, I went to watch some TV on my HD DVR (last time watching on it was this past Sunday) and started running into problems. Everything seemed fine for about 5 minutes, then the picture went blocky until it eventually went out (received 771 message on SAT input 2, only SAT input 1 is used). All of my readings for the signal strength read 0. I disconnected the power and reset which resulted in the receiver getting stuck on the setup screen with a 771A error. I turned everything off and check other receivers in the house to see if they had issues, which they did not. I watched a little TV on another receiver before going back to the HD DVR to see its status. This time I got some TV, again for a couple of minutes, then it went out again. Anyone have ideas on what may be the problem? I can provide more details as necessary.
