When we bought the board, all worked as it should. After time, the board would send some crazy loud buzz through the mains followed by a loud POP! and then the board would not send or receive any signal. This continued for a while, we would reboot the entire system and it would work..for a while. Then it started doing it more often. Now the board will not send or receive any signal from start up. Tested the rest of the chain (snake to mains) with another board without this issue. The issue must lie within the board. Any help would be greatly appreciated.
