I got a PSOne LCD Screen a month ago from amazon and I've been having fun on it. Until something from the screen broke and now it looses balance when it's stood up. I tried unscrewing the bottom part to see the problem. When I screwed everything back up it felt like the volume button was stuck meaning I could not press it anymore. The screen itself still works it's just that the volume is now loud and the screen won't sit still. Is there any thing that is causing this problem?
