psp has no power lights and will not turn on
I have a PSP 1001 and when I plug in the A/C adapter I get no power lights and it dose not turn on. I do hear a slight humming noise but that's all. I think it might be the A/C port but I am not sure.
Can you confirm that the power supply is in working condition? Maybe by trying to charge one of your friend's console with it, to see if that works? Is there a battery inside the unit?
