I have a PSP slim and was changing the analog joy stick. I found that the replacement sticks did not have a small clear rectangular piece like the one I found on my old broken stick. So I places the clear plastic piece on a new stick and when I turned on my PSP my player would move to the side (left). itís a snug fit on the slim to get the stick in place and after trying to resolve the problem a few times the cheap plastic part was damaged. But it did not work before it was damaged. I will call up Sony and try to her a FEW replacements. What was I doing wrong???? Help from some one that knows would be VERY helpful!!!!!!!!
