step 1: to test, can use leaf spring to clip 2 side of diot (orange frame), if work -> check socket and power button line, if didn’t ->tracking and lifting the wires (yellow frame) and replace resistance (green frame) if lost or broke.
step 2: if the button sometimes shorting -> remove capacitor (purple frame).
step 3: watch this resistance (green frame), if rotten -> replace, if lost voltage at 1 side -> lifting to red line or replace IC source.
blue text: finally, take off IC source to measure at this base, if resistance was lost -> broke at cpu.
Note: In reality, just found that broke line by switch was unsensitive or rotten by water.
