Today my motorized (STAB 90/USALS) 90cm FTA dish stopped moving. I tried everything with the receiver and no go. I tested voltages, continuity, and cables and all tested OK. So, just for chuckles I disconnected the cable from the LNB and there she went! Connected it back and the dish won't move. Disconnect and she moves. Replacing the LNB fixed it. That's a new one on me, a defective LNB disabling the dish motor. o_O

Sounds like it was causing a short. Any signs of water infiltration in the lnb?

You were probably trying to move it while tuned to a vertical 13 volt channel, and that lnb was drawing a little bit too much current.

I wonder what would have happened if you had tried a horizontal 18 volt channel?
