I normally would blame the board but recently I have had two new boards stop working after a few days. I am not sure why these new boards keep going bad and I don’t have any devices to check them. The only thing I can do is swap them around and it doesn’t make sense to me why they work for a few days and then stop. I am running BRAIINS software on all machines.
I suspect it may be the control board but I don’t know how to test that theory.
Any troubleshooting advice would be appreciated.
Well, according to your statement here, I guess the problem is in the power supply or it could be with the control board.
And to test your theory, don't you know that once you test the power supply with a multimeter it will provide a correct voltage
to the miners.
Or in another scenario, you can also consult the manufacturer for troubleshooting steps, or
you can also check for the firmware updates.
