Looking at it from here, it looks like someone changed the setting on the ..... Oh, hold it, I was looking at the East Coast of Rock Creek!
As Brian asked, how do you know???? Is this a "Glorystar Mode receiver" Do you see a signal / quality meter and if so what are you seeing? Where on what East Coast are you, as someone might be close enough to take a look, otherwise, with a few answers and a bunch more questions and answers, we can probably get it working. When did it last work, and as asked, which receiver does he have? LNBFs seldom go bad, even when abused. I have one that flew about 800 feet, bouncing a few times on the way. Fortunately, that one had its coax fastened in a way that cut the coax off against the wall mount, so the connectors were still intact - the LNBF still works even though there is a chunk missing of the plastic.
If it just quit working now - the dish probably got bumped or moved. Or one of the connectors went bad.
