I have a 622 receiver running off of a two D500's with a DPP twin and a DP dual. The system has been working perfectly for 2+ years. Problem is all of a sudden I'm getting no 110 or 119, only 61.5 on input 1 but I'm getting all 3 just fine on input 2. However, It seems that I am only able to watch 61.5 on both tvs. When I switch the wires from the separator and run a check switch, nothing changes. Is this a bad separator or bad wiring, a bad receiver, or bad LNB?
