Why doesnt my psp work?

i have tried charging it for a few days,

using the AC adapter without the battery or memory stick in,

using a USB cord to a computer

nothing works

no matter what i do, it doesnt turn on.



when i push the switch to turn it on, the green light is on for 25 seconds then it turns off, but the PSP never loads anything up, its jsut always off.



does anyone know whats wrong with it or how i can fix it?Why doesnt my psp work?
something similar happened to my psp a while ago, if you cleaned it with a substance, it may have gotten some liquid inside. i just let it dry started working again.i doubt its this though, it might be your battery.also if its near a great amount of heat or cold, it can cause it to act differently. call Sony and they may be able to help you, or they can fix it for you.
