Hey guys, I'm trying to get a non-working PSP working again. I bought a Pandora battery thinking that it might help, but nothing is displayed on the screen when powered on. With the Pandora battery and memory stick in, the two lights on the left of the PSP light up and the Power light lights up, but there's still nothing displayed on the screen. I've tried adjusting the volume and pressing the brightness button to get idea of anything is going on, but I didn't hear or see anything.

Does anybody have any tips or suggestions to get this thing working?
