1. have you tried another screen, could be a bad screen?
2. turn your device off, then get a flashlight and look if you can see the apple logo when turning it on, if you can barley see it the back light is gone, meaning you'll need to solider.
3.
The new screen do you have a black tape over by the red ring marked, if not and you see three "gold" stripes you might have shorted the phone.
