Left Joy-Con dead, doesn't work attached to the switch or not
My Joy-Con has been dead for a while. It doesn’t even turn on, no lights flash on the side rail while on the Switch or off. I have opened up both controllers, and swapped the battery as the right Joy-Con still worked. Good battery doesn’t work. “Bad” battery found in dead JC works on good Joy-Con. Not a battery problem. Any help is greatly appreciated. Thank you!
