I found a PSP on the side of the road (no lie). It was working fine, it powered up, could connect to wifi, etc, but it wouldn't read UMD discs. So I bought a new UMD to make sure the old disc wasn't scratched. It wouldn't load either, so I took off the cover, I was attempting to get a look at the UMD drive. Well, I found a small piece of plastic loose in there and removed it, thought that would fix it. All that I ended up taking apart was the front cover. But when I put it back together it won't turn on. I've tried hooking it up to a charger, but i get nothing, no lights or anything. I think I might not have put the green power switch board in correctly. Everything seems to line up fine and it fits into place, but the part I am concerned about it is the brown piece on the bottom of the power switch board, opposite the power switch. It is just to the left of the DC plug. Does anyone have any suggestions?
