For some reason, when my switch connect to the dock, it charges and everything but it doesn’t show onnthe switch, i tried with my brother’s dock, same thing, then i tried with my brother’s switch on my and his dock, both worked, it seems that my switch is the problem, and i noticed a weird thing, whenever my switch is in the dock and xonnected to everything it needs, a yellow lights appears, but with ny brother switch it has a green. How can i fix it?

possibly and issue with the charge port or pi3usb chip on the motherboard
