Direct-TV receiver C51-700 - DirecTV

This question is about "Direct-TV receiver C51-700", with DirecTV channels, programming, equipment, and sports. Our main receiver is in the livingroom; we have two additional receivers in the masterbedroom and a spare room. The issue is the receiver in the masterbedroom is not getting a signal. We went through all the problem solvers but it still just shuts itself off. Is there any help for this or do I need to get a new receiver?
