About a month ago I started losing signal on the SEC Network (ch 611), getting the 771 signal loss error on that channel & a bunch of others. This issue kind of came & went, almost like a weather outage, but it was clear skies. I called DirecTV & after troubleshooting (i.e. having me reset all 5 of my boxes repeatedly) with no success, they offered to have a service rep come out for some obscene fee, plus whatever equipment was required. I declined and I have tried to troubleshoot this myself, but with no success so far. I have had DirecTV for over 20 years and my current installation & equipment are about 10 years old (give or take a couple receivers that were swapped out, but not upgraded). My setup consists of: A slimline dish with a triple LNB (non-SWM) that is very solidly mounted to the side of my house There is no line of sight issues as there are no trees in the way of the dish The dish has not moved as I climbed up & its so solidly mounted to the house that even if I try to shake it, the dish does not move 4 coax lines that go from the dish into a SWM16 multiswitch The four lines go into the four satellite input ports on the multiswitch 2 coax lines that go from the SWM1 & SWM2 outputs into two 8-Way wide band splitters (SPLIT8MRV) Coax that goes from the splitters to each of my 5 receivers One coax line that goes into my DECA broadband adapter (DECABB1MR0) I have 5 receivers. 4 DVRs & 1 standard HD receiver HR22-100 HR21-200 HR24-100 (x2) H25-500 I thought the LNB maybe had gone bad, so I bought a new one. Replaced it, and my signal numbers actually went down. The next step would be to maybe see if the SWM is bad, but since I am getting perfect signals for some of the satellites, I question if that is the issue. Could it be that my dish somehow needs to be realigned, even though, as far as I can tell, it has not moved? Going through the setup, here are the transponder numbers. You can see that the numbers on 101, 99(ca), & 99(cb) are perfect. I start seeing zeroes on 99(s) & 103 is just a hot mess.
