Ok so my setup was working just fine with power inserter in a room I had to paint today. Disconnected the PI from the outlet but forgot to disconnect the other two receivers in the home. We got done painting and I powered up the PI but now non of the receivers gets beyond 775 communications error. I have moved the PI to a different room and removed all power passing splitters so that from PI it's a direct line to the switch. I still get the 775 communication errors. Is it possible that my swim has gone bad???? Anything else I can try?????
