step 1: to test, can use lesf spring to clip 2 side of diot (orange frame), if work -> check socket and power button line, if didn’t ->tracking and joining the wires (yellow frame) and replace resistance (green frame) if lost or broke.
step 2: if power button sometimes shorting -> remove capacitor (purple frame).
step 3: watch resistance (green frame), replace if rotten. If voltage was lost 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: Notice at power button, it wasn’t work when lightly press, you have to hold it a while to work -> check home button line on sensor, error switch part on home line.
