OK, I got a new receiver from DirecTV because my old one kept getting the choppy recordings. Anyway. the new one seems to be just as bad, and since it is a refurb I was going to send that one back and keep my new one. But, I just unhooked the refurb and hooked the new one back up and I can't seem to get it to turn on. The receiver is running, the hard drive or something anyway, but no lights come on and I get nothing to the TV. Am I just doing something stupid, or what could the problem be?
