I turn my multistar maximum on, it boots up and I can get a channel. PPV 503, but that is it. When I try to get another channel in nothing, just a scrambled signal forever. The only channel I get is the first channel I tuned into. I had another receiver at home and the exact same thing happenned, but with a different channel. What is going on? Both of these are from echostar 110. I am also aimed at 119, but have never been able to get the channels in.
