iPhone 4 Died, no water damage!

I have an iphone 4 and it does not powers on. No water damage on this phone indicators are clean. The phone is completely dead, itunes does not recognize it. Tricks like push power button and home button together does not work. No sigh of life in this phone even if i charge it all day. The motherboard is so clean, looks perfect but it does not work. I think its the power ic chip. Can someone tell me how to check this chip?

hi John,

I had the same problem.

i checked the power connector with a multimeter. ( remove the battery, connect the iphone to an adapter (charge it) and see with the multimeter.) if you have power the problem will be at the main board ( or battery).

if not try with another cable/adapter.

i replaced the motherboard, you can find these from other broken iphone's ...

i hope it will work out for you.

good luck

greetz,

Kevin
