whats wrong with my iPhone
well my iPhone 3gs wont charge. We replaced the battery and then it charged again but when it didn't charge the charger was making clicking sounds if you put your ear near it. After a couple of months the same thing happened again it wont charge. We know that it is not the battery because we bought it from apple so its not done. So we opened it up and took everything apart a cleaned everything the dock connector etc. where there was dust and stuff ( with a air duster can ). Well we closed it up and it wouldn't charge so we gave up. We just don't know i said may be a fuse or something like that, but my dad says that it doesn't have a fuse. Or the dock connector, well he said buy dock connector then, but i wont until I am sure what the problem is because. I don't want to waste my money on things that don't need to be replaced. so yeah i really want to know whats wrong with it thanks guys
thomas, couple of things that stand out to me. first, just because the battery "bought it from apple so its not done" does not mean that it won't fail. Always remember that these batteries do a lot more than just store energy. You said you replaced the battery and that it then charged. I definitely would be looking at getting a new one, again. The other thing I am unsure about is your statement about the "charger was making clicking sounds" you should definitely try to either replace the charger or try to charge your phone with a different charger. Next thing, yes it could be the dock connector. Since you already cleaned it, I also make the assumption that you checked for bend or broken pins as well. If after you installed a new battery and tried a new charger, it should still not charge, you can replace the dock connector, using this guide. You do have fuses on the logic board, there are actually two that could be giving you trouble, check the attached image to find your fuses and check those with a multimeter. Last but not least, you may have issues with your PMIC, which would require either a reflow or a reball of the IC. Hope this helps, good luck.
