Component Involved:
| 1 | 12V Power Transistor |
| 2 | 5V Regulator |
| 3 | IC Chip |
How to check transistor:
Attach multi-meter testing pen to both end of regulator, measure 12v while main power supply to MCU board.
Replace it if the values lower than 12v.
If Regulator works well, replace the Power IC (2) at priority, follow by IC Chip (3).
