I just recently got a 30" Wineguard dish with lexium satellite receiver 7000 series. I can't get any kind of signal, I've moved it up down and all over the outside my apartment. It keeps saying (Signal strength 87%) (Signal quality 14%) it can't get it to go anymore higher that. Not even the slightest amount of a picture. Could this be a bad lnb or interference? I took the lnb off and it still jumps back and forth on the signal strength. The rest of the hair I have on my head is about to come out.
