I purchased a nintendo switch to repair; I came here to ask for advice about what may be wrong with it.
Board: PWB/ AU/ CHN HAC-CPU-01
Fuse has continuity
The battery does not charge, I plugged it into the usb c charger w/ battery and left it for 30 minutes result being battery went from 4.06v to 4.02v.
There is a shorted capacitor on pin 18 of the MT CHIP
