I had the same problem. living in Rockford. It came back on after 10 last night.Maybe I should check the LNB.
Actually the OP noted the ice covered LNBs as the problem (along with a minimal amount of snow on the dish).garys said:With the large area of destruction from the tornadoes in Indiana you should consider yourself extremely lucky. Disrupted weather between your dish and the satellite is enough to cause signal loss to the point of no signal, I would gather that is where your disruption came from. Don't think your equipment is at fault.
