Hi community,
I turn to you as I need some help if possible.
I have an Antimner a3 and one of the boards is not working. Tried changing power, moving back and forth but always the one in the middle (board 2) do not work. Tried booting the Antimner only with it connected also did not work.
Sometimes the board will not show at all, sometimes (when I lower to 550 )will show with few Asics but all XXXX XXXXXXXX.
Tried factory reset few times, tried power off/on, restart .... none of it changed anything.

Any ideas if there is any chance I can fix this other then sending back to Bitmain?

p.s. if anyone manages to help me to solve this will permanently mine for you for a day.
