A few days ago I had shocked my controller by accident going to reach for it and after doing so I noticed the controller wasn't acting right. I plugged it into my laptop to check the buttons and it seems Button 4 (Triangle) is stuck. Usually, as I have discovered, that would mean there was something stuck in there. But there isn't in my case. I was wondering if there was any other solution or if I would have to resort to getting a new controller. I have no idea if the warranty is on there still, I had bought the PlayStation refurbished from GameStop last June so I would guess not.
Any help would be appriciated!
