I am looking for some help.... I received a new receiver and dish from dish network to install at a family cabin... I mounted the dish with a clear view and have a signal on the dish pointer screen of 70 but cannot get the signal to lock? I get the program guide to download, but when I go to a channel it shows the program in the guide but no picture (black Screen). Any suggestions or help would be appreciated. The reciever is a VIP211 (I think) and the dish is a 500 with a dual lnb (it has 2 coonetions on the 119 side and one on the 110 side). I installed one coax to the 119 side of the LNB and ran it approx 125 feet to the receiver. But like I said the signal bar goes to 70 but is red and won't lock?
