My Problem

Iphone 4 I had the screen went out and went black was working but could not see the screen heard jingling in the iphone.

My Fix

Did not go well stripped the phone down as per instructions keeping track of each screw and part put it back together and still no dice will not light up and still have a jingle in it

My Advice

Can't think of any other than pay attention of the screws and where each part is
