2 days ago I had a new roof put on the house. The roofers removed the dish and reinstalled it in exactly the same location. Well, maybe NOT!! I only receive some HD channels (including locals) and nothing else. When I go to the Installation menu and check switch it says everything is OK for 119, 110, 129. When I get system info, i get red X's for 119 and 110 and a yellow bar for the 129 sat. I contacted Dish and they want $95 to come out and fine tune it.. that is ridiculous... Can anyone help? My receiver is a ViP722 DVR-HD with software version L625.
