Power off and wait 30 seconds.
Open the miner and reseat the ribbon cable connecting the affected hashboard to the control board.
Inspect the ribbon cable for any damage, bent pins, or corrosion.
Check the power cable connection to the hashboard from the PSU.
Try swapping the hashboard to a different slot to determine if the issue is the board or the control board slot.
