I replaced my digitizer or part of my screen or whatever you want to call the top part because it had cracked due to heat and was unusable. It worked and lit up but had faint lines through it and the back button didn't light up an a couple random things like that were a bit funny. I took it apart again to fix the lines and now it won't even light up. The buttons light up, (well one does, not a biggy), and the screen lights up but stays black. I even tried a third digitizer. Any help, suggestions would be very much appreciated. No idea if this is even worth it. THANK YOU!!!
