I tried to fix Switch v2 which had a problem outputting image to the TV. When I insert the switch to the dock, the green dock light turns on and the TV changes to the correct HDMI channel (HDMI-CEC function). The charging also works via dock.
I used original dock and charger. The dock works with another switch.
The USB-C port and the pins looked fine but the console itself was a little bit bent. I did not try to replace the USB-port.
I checked that all the capacitors around the three ICs’ (P13USB, M92… and BQ…) were fine. Also the chokes/filters connecting to the P13USB were fine also (continuity test).
Any idea what other troubleshooting I could’ve done, except for the USB replace?
