Won't turn on after attaching to car charger
One day I wanted to try out a new car charger I got and plugged in my phone didn't hear the charging sound so went to look and the phone was off haven't been able to power it on since and have tried everything. I checked the output on the car charger with a meter and it's the correct voltage so i'm thinking maybe it was a defective cable. I opened the iphone to see if maybe the battery went bad all of a sudden, I get the correct voltage on 2 pins of the four I think the other two are for charging, so I don't think the problem is the battery. Does anyone have an idea what i should try to troubleshoot next or what parts i should buy from ifixit to try and revive my phone.
Thanks in advance.
