I use to be a DirecTV customer and still have the 3 LNB HD dish on my roof. Since the storm our cable is out and I want to use my brothers receiver for a few days. I can't get receiver to work. I think dish might be damaged. Not sure, please look at attached picture. Also, I have 4 RG6 cable going in to a 6 X 8 multiswitch, but I think they got mixed up. How do I figure which cable goes where? Thanks for the help. Anyone?
