Sometimes we can solve control board problems by upgrading the firmware. However, if flashing the firmware is useless, it is recommended to use a new C52 control board to replace the faulty one immediately.

A damaged control board can cause:

• Miners cannot obtain IP

• Unable to enter the miner's backend

• No hash board detected or no hash rate

• Fan not detected

• None of the indicator lights on the control board light up
