Trace shorted power lines directly from the DC jack through the input MOSFETs to the shorted ceramic capacitor. 3. How to Find the Right Boardview for Your Board
Click on any pin of the component. The boardview software will highlight every other pad, via, and trace on the motherboard that shares that exact electrical line. If a trace is broken internally, you can easily use this feature to run a physical jumper wire from point A to point B. Hardware Diagnostic Reference Table
