I have 3 of these that are 4-way. Before I got the third one, on the first 2, only one port would work. In the beginning, all 4 ports worked on both, but it gradually got to the point where there was only one working port on each. So I now get this third one, a brand new one at that. The Ebay seller who sold me my S9 recently, he included one of these. So I've had it for probably around a month I guess. Just like the first 2, all 4 ports were working in the beginning. But now I'm down to just one port working on this one as well. What in the world is causing this? Do these ports just randomly malfunction at some point without warning? Anyone else experience similar problems with DiseqC switches? This is not receiver related. I have an old Lifetime Ultra. I plugged that back in just recently, so I could see if any of the other ports worked on any of these switches. Same thing, just one port worked on each. Are these things pretty much toast now, or is there a way to fix this?
