Hi all, Long-time lurker, occasional poster... My set-up is as follows: SWM LNB with 1x8 green-label splitter. The splitter feeds one HR24, one HR20, one HR22 (total of six tuners) and one broadband DECA. All unused outputs are capped. Last week started getting 771 and 775 errors on HR22. It coincided with an extreme cold snap in NY and I figurd I probably had an outside wiring/connection issue. I checked all connections at splitter and they looked fine. I'm too chicken to get on the roof, but figured if it really were a problem at dish or LNB, I'd be having problems with all receivers--which I wasn't. Here's where the tail-chasing begins. I noticed at one point that all lights were out on the DECA at the HR22. I figured the DECA went and DTV sent me a new one. I installed it, but again got intermittent 771 and 775 errors. Next, I swapped the HR20 and HR22 and got the errors on the HR20 which seemed to implicate the wiring to that location rather than the receiver itself. Next, I replaced the barrel connection on the RG6 run to the problematic location (at the receiver) because I felt like maybe I could provoke the error by jiggling the wire. Now I'm just observing to see if the errors recur. But here's my last question: When I do a satellite signal test, I get 0's on SWM at transponders 2, 4, and 7 for both tuners on the HR22. Is that normal? Many thanks. Other suggestions most welcome!
