After snow storm Wednesday morning caused power to go on and off a few times before I unplugged the entertainment center power strip, we lost all satellite communication and are getting error 775 on all 3 receivers. I cycled the PI and did a RBR to no avail. Called CS and they walked me through same. Anyway, tech is coming Monday, after the Super Bowl. System: HR24, (2) H24s, slimline 3. I've been trying to troubleshoot this myself to get it back by the SB game, and to learn a bit more about AV wiring, etc. PI is outputting 20.8V at the unit and 20.4V at the cable connecting to LNB. Video signal is passing tests (Klein VDV Scout Pro). 1) From what I've read in other posts, this may be a bad LNB? 2) Just curious about this part: I placed remote #1 on end of cable at LNB, but the Scout Pro (at wall jack before PI) read it first as #8, and second time as #7. Is the number different since it is going through the multiswitch? 3) I attached pics of the cabling at the dish. I like the extra cable left coiled up on the back. But, why would there be exposed connections here? Just curious, as I'm all for no exposed connectors.
