Pocket PC Accessories

so my analoh stick has been reacting lately. so i watched a whole bunch of videos on how to fix it, i have got some help. i opened my psp took the faceplate and messed with the analog stick thing, so ive tested the internet browser without the analog stick in place, then my cursor continues to react wierd and starts going to the upper left, so i randomly started putting random pressure on the plastic thing that covers the four gold chip things and still nothing..is there a way to fix this? i tried cleaning everything and nothing worked oh...and my analog stick barely responds when applied to the psp. (im using the psp fat)
