I replaced my controller joysticks because of stick drift. After I put together my left controller, it had stopped working(i saw a capacitor was missing from the motherboard). Is there any way that I can buy a non-overpriced motherboard replacement?

I have a gtx 1050 laptop and it was working with the quest link, but with a new update it says it isn't supported. The GPU worked perfectly fine before, it was just a little slow. But now, I won't even be able to try.
