I have a Pokemon Scarlet joycon that stopped working after I opened it up for a repair. I double/triple checked everything and it’s all connected, I let it charge and nothing. I don’t really want to send it to Nintendo since they don’t guarantee a replacement of the same style. Should I take it in somewhere to be looked at, or should I just buy a replacement and do a shell swap?
Check the pins on the joy-con side and switch side to make sure they aren’t damaged or full of junk, try with a friends joy-con if you can to test it’s not the Switch tablet. If those look clean, try unplugging and re-plugging the internal battery of the joy-con and try recharging. If that doesn’t work and the joy-con motherboard doesn’t look damaged from liquid etc, you can try a new battery from Amazon for the joy-con for pretty cheap before calling it quits on that controller.

Bought a Hori split pad for a temporary replacement and it worked fine… Until the opposite side stopped working lol. I know the tablet is fine though because one of the split pads works and one of the joy cons works at the same time.
