Sitch is not charging

Hi,
I have a issue with a Nintendo Switch the Seitch was not turning on so i mesured some caps and ics the big cap under the bq had a short and the fuse was broken so i replaced the fuse the cap and the bq and also the battery.
The switch was now turning on and also the battery charge symbol lighted up. But the switch wasnt charging the battery. When a plug in the usb tester the switch drains 0.1 amp at 5 volt but at 15volt it drains 0amps. I mesured all caps around the bq abd the m92 but there are no visible shorts or damages.
Can anyone help me?
