Last night everything is fine. I get home this afternoon and turn on the tv and I have no satellite signal. The HR20-700 is working fine, I think. The guide and menus work, so I reset from the menu. It cannot find a satellite signal. I unplug from SAT input #1 and 2. I then RBR. It is still searching for a signal. This time it beeps/chirps through the center channel speaker. I have went out to the dish. I cannot see anything wrong with the cables. I also have two D11-500s and they are working fine. Any ideas?
