I had a near lightning strike that took out my receiver, TV, and SWM (in addition to my modem, router, phones, thermostats, oven, etc.) Got a new TV, DirecTV sent me a new receiver, I put in a new SWM and have replaced the lightning arrestor but I'm still not able to see the satellites. I have 20 volts in the cable at the dish so it would seem the cables are still good and this SWM is working. Is there anyway to test the LMB without dropping in a replacement unit? I've found them on Amazon so I'm assuming others have found they also need to replace this component. The dish is called the AV9-SL3-SWM 3 LNB. Thanks for any trouble-shooting hints.
