• My daughter was upgrading her PSP via a new game which when the error message appeared the wrong disc had been inserted. Now the PSP power light appears for about 20 seconds and then turns itself off. Please help!!!
  • Assuming the PSP has not been modified in any way and is not running any unofficial software...

    Take the game out of the PSP then try restarting it again by holding the PSP power switch up for about 15-30 seconds.

    If this doesn't work, switch off the PSP and charge it for an hour before trying again without the game inserted.

    If this still doesnt work you can try this at your own risk: Disconnect the power cord / remove battery and hold the PSP power switch up for about 15-30 seconds.
  • If it was in the middle of the install when that happened I fear the PSP may have become "bricked" and will no longer be useable. If none of the tips Jim gave you up above work I would contact Sony about getting a replacement unit (that one year warranty comes in handy).
