Game controllers are easier to repair than you think. I recently had a button stick on my PS4 controller and just youtubed "PS4 button stuck" then followed some tutorials. Problem solved. Also had a WII controller that would not stay on. Would turn on, then off after a few seconds with full battery. Took it apart and cleaned everything with rubbing alcohol, but no joy. Tried this 2-3 times. Finally read comments on some youtube videos and one user suggested vinegar to remove any battery acid, followed up by rubbing alcohol. Hot damn! It worked!
