This is my setup, I have 4 receivers, 2xStandard, 1xHD, 1xHD-DVR, 5-lnb dish, and an 8-port zinwell multi-switch.
Everything was working perfectly. Then suddenly on Friday Night, the 2 standard receivers stopped working completely and gave me the 771 signal message, not a single channel works on either one. I then found that at the same time, the other 2 receivers which are the HD receivers are working perfectly fine, except after I look through, one of the local sports stations (SunHD) also gave me a 771 signal message when I tried to watch it on both the HD receivers. What's funny is that I could still see the other local sports channel (FSN-FLHD), that one works fine.
First thing I did was check the signal on every receiver, and every receiver gave me the same results. Even the 2 standard receivers that don't work at all on any channel.
Sat: 101 - almost 100 on every odd # transponder, 0 on every even # transponder.
Sat: 110 - almost 100 on transponder 8,10,12, N/A on all the others.
Sat: 119 - N/A from all transponders 21 and below, almost 100 from transponder 22 and above, except for 25,29,31 which are 0.
Sat: 99(c) - Up to transponder 14, almost 100 for odd #, 0 for even #. All transponders above 14 are N/A.
Sat: 99(s) - 0 or N/A for everything except transponder 15,21,23 gave me 100 signal
Sat: 103(s) - 0 or N/A for everything, except transponder 3,5 gave me less than 30 signal, and 16,20,21 gave me 60 signal.
Sat: 103(c) - All transponders up to 14 gave me a 70 signal, all above 14 were N/A
I checked every connection to the multi-switch and at the receivers, I reset and re-did satellite setups on all the receivers, everything was still the same. I then tried to swap the cables on the ports of the multi-switch and nothing changed either.
My confusion is, if it were a sat or multi-switch problem, then wouldn't all of the receivers have the same issue? Then if it were a problem with the receiver, it's too much of a coincidence that all at the same time, 2 receivers go out completely, and the other 2 lose signal on 1 specific channel.
I'd appreciate any troubleshooting advice to see what else I can try, thanks in advance
