I have three sat. one on 110 one on 119 and the other on bev. The signals on the 110 and 119 are strong , ant the one on bev was great until the latest bin change. Since the change I get nothing and the dish has not moved.The other two sats are the same strength. What can I do to get the bev back it is located on disq.3 the others on 1 and 2. Could I have switch problems
