Computer not starting, fan just blows for a few secondsHi everyone! Since there aren't much reading about problems other than heat issues I have something new and flashy for you...
"replaced broken glass and now it won't power on, why?"に関する回答Did you remove the LCD when replacing the glass?
"I replace my screen and now my iPhone 4 won't charge!"に関する回答If Brad's answer doesn't work try restoring your phone. You don't have to do that in iTunes if you have iOS 5.0.
"LCD Replacement no display"に関する回答Did you remove the front totally again? Because if you managed to scratch the display-cables when installing the LCD then it won't work. Most likely it's a LCD that's not working.
