":confused:  OK I aligned at9 dish today. Had reading of 84.5 at back of dish after fine alignment. came in house to verify signal on hr20, everything initially looked good. I was able to see a picture on several channels for about 10 minutes while getting receiver activated, then all of sudden i lost all signal on 101 and most on 119. I don't see how the dish could have moved..everything was tightened down pretty good. I did check signal on transponders before I lost signal and all seems pretty good...readings from 70's to 97. Now all I have is 0 across the board. It is not a receiver problem...I hooked hr20 up with old round single lnb dish and 101 is fine. DO you think the dish really moved as tech support insists or could the lnb's fail or what......frustrated at this point."
