Signal problem

[doc048]

I am trying to set up a Coolsat 4000 pro system with a motorized mount and a dual lnb. Cannot get any signal today after it was getting some signal according to the signal meter on the tv display yesterday. The motor moves but checking the volatage at the LNB and it is just a trace voltage of about .5 volts. Any ideals as the the problem. I am not that familiar with FTA
