Common troubleshooting methods for the KCZ-1230A board can be summarized as follows:

‌Power supply problem‌:

‌Check the power supply‌: Make sure that the 12V power supply fuse and TVS are normal, and the core, CPU, and 3.3V power supply voltages are normal.

‌Power-on sequence‌: Check the power-on sequence of the power supply to see if it is powered on from low voltage to high voltage as required‌1.

‌Connection problem‌:

‌Pin connection‌: Check if the pins are firmly connected to avoid looseness that causes an incomplete circuit‌.

‌Short circuit check‌: Make sure there is no short circuit and the pins do not touch anything they should not touch‌.

‌Component problem‌:

‌Component polarity‌: Check if the polarity of the component is correctly connected, such as batteries, electrolytic capacitors, etc.‌
