I used my PSP last night and picked it up this morning and it wont play any UMDs ( all of my UMDs are American, store purchased disc). the second you open the disc tray the PSP acts normal. If you start it up with the disc tray closed- it goes to the load screen with the little "loading" circle in the bottom left corner. if I have to send it back to the state to fix it I will but I would like to fix it on my own if i can. any help would be appreciated!- Thanks
