psp power problems...

[custm_made]

so heres the deal, my psp will not start up. when i put a fully charged battery into my psp and try to turn it on, the green power turns on for a split second. when i put my pandora battery in, it flashes rapidly and continuously until i remove the battery. ive tried to look on the net for people with similar problems but no one knows how to fix it. does someone here know whats wrong with the psp and know how to fix it.

I have this same problem for one of my motherboards. Many people people cannot fix this problem but some say its just a short inside your PSP.
