did you do anything to your power board when you took it out like mod it or somthing? and try it with another power PCB

i found something interesting today, i put on pandora to see if it would turn on(for some reason i had a dream that if i put pandora on the broken psp it will some how help me find the problem.) after i put it nothing seem to work. But i was just curious and got my screwdriver and touched the memorystick led with one of the resisters next to it and it turned on. i also touched the lcd cage and the positive side of the led and it also turned on. Any one know whats making the mobo not turn on?

If you put back the motherboard wrong and it touches the metal lining, it'll create a short and will cause the PSP to not turn on. Disassemble the PSP and reassemble it correctly.

thanks that was the problem. its working now
