I haven't been able to use it in many months (because I've been using its' battery for my PSP 3000 instead (it was the only thing that solved that issue). BUT when I did try using the 1000 the buttons seemed to be sticking or needed to be pressed very hard for any kind of response. I'm wondering if this is an easy fix or not. I am willing to open her up cuz she's of no use to me now as it is (and I have other PSP's that work) so if I mess up and it becomes a loss I won't mind as much but for the time being I don't even have a battery for the unit. So any tips will be gladly taken but I won't be able to update my status for a few weeks while I await a new battery. I basically made this thread to see what people would say as I don't know too much about the hardware of these individual devices, I only know the software part, I'm a PSP theme creator...not hard modder.
