I am having trouble with one of my iPhones I bought to repair. This one is having overheating troubles and I have no clue how to fix this. It does not charge when plugged into the computer but when I put a fresh battery with a charge in the phone it powers on just fine but heats up extremely fast and shows the temperature warning on the screen. The heat is coming from the part of the mother board just above the connector for the docking port. It also does not appear in iTunes when plugged in. I have fixed many iPhones before but I can't seem to find a way to fix these problems.
Thanks in advance for any and all help.
