- Today we have a Nintendo Switch HAC-001 console which is dead and won't charge or even negotiate 15 volts from the usb-c power supply - removing the battery and testing with a usb-c signal finder board to show missing signal/power lines from the usb-c port and also a look under the microscope shows the usb-c port is OK - testing around the M92T36 USB-C power management IC and I find that the middle capacitor of the 3 caps in a row measures short to ground - the 2.2uf capacitor is connected to pin 39 of the MT92T36 which is one of the internal LDO pins and removing the IC from the board removes the short. Soldered in a replacement M92T36 and now the switch correctly negotiates 15 volts from the usb-c port and charges and boots...
