I have the basic HD receiver and just started having trouble with my HD cable. I have a Vizio 37 in HD tv and it says no signal and I get a blue screen when I hook up my HD cable. Sometimes I can jiggle it on the back of my Dish receiver, but now that does not seem to work. Is there a way to clean the connectors or plug? I tried 2 different cables and 3 different HD ports on my tv. Or will Dish have to come out and replace the receiver?
