(adsbygoogle = window.adsbygoogle || []).push({}); Hi I have a sprint iPhone 4 that screen cracked
I bought a new screen from online I put it and replaced it into my iPhone
Everything is connected on right but everytime I press the power button
Only a bright glow shows in a black screen.
Everything else works like the sound, vibrate and other features but the image won't project into the
Screen allowing me to see what's actually happening.
What do you think it might be ?

Sound like you messed something up, Put the cracked screen back on and take it into an Apple store they should fix it or maybe give you a 4S to replace it.
