I've already had two EA hybrid lnbs go bad and both had exactly the same symptoms so I figured it was worth mentioning. The symptom is that the signal will just drop for no reason and then come back....the length of time of the outage will get longer and longer. We've been having torrential rains the past two months so at first I was just thinking that was the issue but we had a few days where it didn't cloud up until later in the day but customers were still having signal drops in the morning when the sky was clear blue. Replaced lnb, problem went away.
