After some unfortunate events, the PSP was hit on the floor twice. It is now broken and I am now trying to find out what is wrong with it. Physically, the only thing that happened is that the front case is shifted forwards. When I turn on the power, the green light goes on. Nothing else goes on. No whirring sound. It's a PSP-2000, and I have no idea what to do with it. Do you guys have any idea on what is wrong with it?
