Any changes in the logs? I hope that you post the new logs here.

If is it still the same as the logs from your post above then the control board is already damaged.

I don't know if this one will work but would you mind to try to test the hashboard one by one? Disconnect the two hashboard from the control board. Do this to all hashboards and find which one is not detected properly and maybe one hashboard is shorted. Then compare all logs between these hashboards.
