Hi I replaced my cracked phone screen and it went well until I tried to turn it on. The new screen is just dead black with three small streaks that show the back light. When I plug the old screen in (via the digitizer ribbon– not with home button or camera) it still worked. The new screen seems to have everything installed correctly, and I reviewed the proceedure multiple times. Is the new screen broken? It has a small red band painted on the digitizer ribbon. Thanks, J
Sounds like the new part you’ve tried is faulty. I would order a new part and see how that one works. iPhone 5s/SE LCD Screen and Digitizer - Choice - Fix Kit / Black
