I have the HR-20 and 5LNB dish. Yesterday my signal dropped out on the second tuner for SAT 119 and also my signal strengh on other SATs have gone down some except 101 which is still at 98%. I was getting in the 90's on just about everything before this happened Tech support had no answers HD locals were coming in but all HD channels (nationals) did not. Message stated searching for SAT on 2. They had me go back through the satellite setup and that said both tuners and all satellites were OK, but this did not help. Any possibilities on what might be the problem????
