Hi Rany, Regarding the answer you wrote, I think that I broke the display circuit on my i phone 7. When I changed my screen, I tought my phone was switch off but it wasn’t. Now when I plug the old or the new screen, it doesn’t display anything but I can feel that the phone is still swich on. Do you think the piece of the phone I broke up is the display circuit? Can I change it? Do you know some tutoriel maybe ? thanks for your help!
did you disconnect the battery first
If the home button feels like the phone is on and you didn’t disconnect the screen to work on the home button I bet you damaged a screen ribbon. Turn the phone off. Disconnect the battery then disconnect everything else. Make sure the home button is seated and connected properly and the plate is fitted. Reconnect the ear speaker flex and the screen and home button connectors then finally the battery then try it. If the home button works and the phone vibrates when you flick the mute switch then I’d say it was a screen issue. If you didn’t disconnect the screen and battery whilst working on the home button I doubt it would cause a back light problem.
