Question My satellite was working but I am getting searching signal with humming noise. I replaced LNB, still no signal. What is the problem?
Answer Anozie, it could be one of many things:
Maybe the dish got knocked off alignment
Maybe something happened to the cable or connection
Maybe the receiver became faulty or blown a fuse or just the programming got erased or tampered with
Some other possibilities or combinations are also possible
