Hi guys! I just got my first S9. Everything went just fine till morning when one of the 3 hashboards stopped hashing. I tried everything, unplugged, reset, psu cable variations, update the firmware, but nothing. In the status everything seems normal, only the GH/S(RT) shows 0, everything else is the same like at the other two. Any idea what should I do? I would not like sending it back to bitmain. Thanks!
