Completely dead iPhone 4
Hi,
I have been replacing iPhone screens and doing general repairs for a while now. I have been given a dead iphone 4 to look at. I initially thought that it was going to either be the battery or the dock connector. I have tested the battery in another phone and that works fine. I also bought and fitted a new dock connector (which i have done before) and still have nothing. Can't get any sign of life out of it whether it is plugged in to a mains adapter or plugged in to the pc.
Any one have any other ideas to what the problem could be? I'm hoping it's not the main board but don't really know what else to try/swap without spending money that I don't need to.
Any help would be appreciated.
