OK so basically a friend at school just bought a psp (used) and brought it to me saying it wouldnt turn on. I brought it home today and I could not get it to turn on, I tried new batteries and running it through the charger etc. When I plug it into the wall the charge light does come on. Also I used a Pandoras battery and it finally turned on, however all i got was a black screen because thats what pandoras battery does. I dont have the magic memory stick yet, because I am goiong to make it once my card gets here through the mail. Basically I am stuck and dont know what else to do or where to take it to to get it fixed. Any hel;p/input would be appreciated. My guess is that the power switch is broken.
