Whatsminer M31S hash board troubleshooting for 17V boost circuit

The 17V boost circuit on the Whatsminer M31S hash board mainly boosts the 13V input voltage to 17V, and then supplies it to the LDO chips of the last 9 domains of the hash board. When the voltage of the LDO chip in the last 9 domains is abnormal, it may be because the 17V boost circuit is faulty. At this time, we need to check whether the components of the circuit are damaged, and if so, replace them first.
