I would advise you not try to move the dish yourself. I was losing channels with rain and fog and after a couple of calls/complaints, a service man came out and told me my dish was warped, which probably was done on the truck that delivered it. He tested the signal inside on the tv and I was getting less than 50% signal, but when move a tiny fraction, the signal rose to 94+%. The service man who came out told me the call center people work from their homes, so the responses can differ quite a bit from call to call. Keep calling and once it is fixed, as you know, the picture will be worth it.
