Wolfin2010, check your AC adapter with a multimeter/voltmeter just to make sure it works. Also check your cable and make sure it is not frayed and in good working order. Check the plug on your PSP and make sure it does not have any corrosion or other damage. If all that checks out, I would try a new battery. [guide|1181] after that it is time to reevaluate. If you are really handy, check [http://psx-scene.com/forums/f158/psp-go-fuse-locations-96011/|on here] for the fuse location of your go and check your fuses to make sure they are all okay. Hope this will at least get you started. Good Luck
