anybody who has opened up their psp to replace the screen or just to see if they can, when put back together has your analog stick "stuck" to one direction? i just recently replaced my broken lcd screen and when i put it back together, i tried to play tony hawk and my character wont stop running around. i took it apart again thinking maybe i bent something accidently but it all seems fine. does anyone have any experience with this? am i screwed again?
