Nintendo Switch HAC-001 - Dead, won't charge, won't negotiate 15 volts from usb-c - Repair

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.
