Ok I have an iphone 3gs that has been dropped. I have replaced the whole top assembly lcd, digitizer, glass, etc. I also replaced the mic, speaker, dock, battery, audio headphone jack flex cable with power button, mute, volume, etc. The only thing not replaced is the logic board. I have plugged into different computers, used different cables, into walk sockets, etc. I have held every button 100 times to reset, reboot, start up, shut down. With itunes without itunes. I dont know what else to do. I had a good battery and the next day it was dead but I never saw anything come on.
So I am sure it is somewhere in the logic board of my iphone 3gs but I can not find any help on line about troubleshooting logic board or what to do or look for. Can someone please help?
