I had my Dish with 522 receivers for 4 days (as of yesterday) when in the middle of watching live TV I lost all signal. I tried doing a hard boot, and just get the message "aquiring satellite signal" step 0 of 5 which never goes past 0. I called Dish and had them walk me thru a system check and it failed. I literally was sitting there watching TV when it went out, so nothing has changed from the time they installed it. Any ideas what could have happened? My cable internet still works great which is sharing a diplexed line with my Dish...so I know the connections are intact. My guess is that the problem resides with the LNBF or in the 522 itself...however, I can still watch previously recorded shows on the 522?!? Any advise is greatly appreciated. I'm not having a lot of luck!
