I recently had to re-align my DISH 1000.4 due to signal loss on HD channels. I did this today and after doing so I got signal increases on 61.5 (10 to 35) & 77 (30 to 52), but now I have NO signal from 72.7. All switches check out and nothing other than the dish was touched. Shouldn't I get at least something due to the proximity to 77?
