I replaced my screen on my iPhone 6 Plus (which was powered on working before I replaced it) someone told me my digitizer was going out. Anyway it will not turn on and no vibration. I took it to the Apple store they told me it just needed charging. And my phone should be working. Charged about 10-15 min still nothing. They tired to replaced my phone for 356$ I told them I’d have to thank about it. How come this is when before I replaced my screen it was on and now it’s not doing anything
Try cleaning the Contact pins of the digitizer, it might work. And also check if ribbon cables are tucked in properly.
Do you have the original screen (in a somewhat working condition, of course)? If so put the original screen back in and see if it works with the original screen.
