i just recently got a PSP 3000. put memory card and battery in and plugged it in. set it to english from japanese. it worked fine, but then i put an UMD disc in and when i tried to launch it it turned off and won't turn back on. this orange light is on and sometimes when i flick the power switch it briefly turns green, but the screen never turns on. i've tried taking the UMD out, taking the sd card out and taking the battery out. please help me, i just got it :<
