PSP Fault. Please help !

[leesub2002]

I have recently bought a psp for my son. He has purchased a new game which requested we down load a newer version, which we did try and do. It seemed to have failed. Now when we turn on the psp the green power light comes on but the screen is black and then it just turns itself off even though it is fully charged.

Can anyone please advise on how to rectify this problem.

Thanks

Assuming you got a usb cable with the psp, hook that up to your computer, and if you've installed the disc you got with it, you should be able to upgrade. If not, go to this site, thet should be able to help.

Also, with the start button, make sure you haven't pushed it up into the lock position, i know this has caused a lot of confusion to a lot of people, simply pull it back down to midway.
Failing all this, if you bought it from a shop recently, just take it back, if they can't rectify the fault, they are duty bound to give you a replacement.
I hope any of this helps, good luck.
