My psp will not play games i put one in and it takes about 5 minutes to load and then says disk cannot be read and these disks work in my friends psp so it is the psp. I have cleaned it with a q tip and still won't work i have taken the battery out and let it sit then put it back in. I wanna know how to fix it or if i cant fix it how much i could get out of it. This psp is refurbished and the warranty is over. Please HELP!!!
