blank screen, after the Apple icon shows for 5 sec
After replacing the power button, my Iphone showed the apple icon for 3 min. I've pressed both(power button and home) buttons for 10 sec. and the screen showed "connect to itunes image". Then I tried to restore it, but the screen shut off after 3 min.
I've tried everything to get the screen of the iphone working but nothing works. Even reassembled the iphone again. It helped: showed the apple icon for only 5 sec.
What am I doing wrong? The battery is 4.1 volt. Is it the motherboard?
Is this a good question?
