Switch Lite 15v 0 amps

Having an issue with a Switch Lite. Initially the unit was only getting 5v with something 0.09amps when plugged in and the battery not charging. Poked around looked like one of the caps by the m92 chip was shorting. So I replaced the chip and the short was gone, and now the unit is displaying 15v 0amps and the battery is not charging. OK…so no shorts around the bq24 chip but I changed it anyway, still the same output 15v 0amps. Ok…so for the fun of it I changed the USB-C connector…sigh…same deal 15v 0amps no power to battery. Anyone have any ideas???
