I think best solution is buy a new one from Okuma.

Hi, friend. First check the appearance, observe whether the oil mist parts are burned, whether the line is broken; then test the short circuit, USB, memory power supply, CPU power supply, bus power supply, etc. However, as a novice, it may be difficult to carry out maintenance, you can try to seek help from after-sales technicians.
