Okay, here's the skinny. Recently had to replace the shell that this PSP 2000 came in. finally got the parts the other day, and for the most part everything appeared to visibly work. However, now I am left with a couple of problems. Though everything appeared to be fine when at the XMB, when trying out Gran Turismo I find that the car is constantly pushing left, even when I am not physically touching the d-pad at all. But even after a couple of times of opening it up, reseating it and putting it back together, it's still doing it. the third-party extended battery that worked perfectly fine before the change in shell seems to not be recognized as plugged in anymore, which makes no sense. Stranger still that it does operate with the spare Sony battery I was able to find later. However, that makes no sense to me when all I did was change the shell, you see. So... what should I do here?
