  1. Check if there is a short circuit in the input of the DC-DC converter.
  2. Short circuits are commonly caused by faulty MOSFETs, and individual boards may also have damaged capacitors.
  3. During the repair process, first remove the suspected faulty components. Once they are removed and there is no short circuit, install the good components and conduct testing.
