I think my SWM16 is defective, but am wondering if I've overlooked anything in my troubleshooting, so expert advice is welcome! Recently I noticed that all of my DVR, Receivers and Genie are missing the odd transponders on just the 103º satellites. My 5-LNB dish receives all transponders on the other satellites just fine. Here's what I've tried so far: I tried powering off the SWM Power Inserter and repowering it, but that didn't help. Thinking it might be a problem with a coax connector at the dish/LNB, I checked those and they seem fine. Also checked the connections at the SWM16 inputs, and they seem fine. I swapped the input cables at the SWM16 to see if the problem moved to different satellite/transponders, but it's always just the 103º odd transponders missing. So I pulled out my old SWM8 and connected my Genie DVR directly to it (via Power Inserter), and all transponders are received normally. Reconnecting to the SWM16 shows missing odd 103º transponders again. So, seems like a defective SWM16, right? Anything else I should try? Thanks for your advice!
