So I had someone come to me with a replacement part to out on their iphone 6s plus. Done the usual, ground myself out, remove battery connection. Removed the screen, plugged in new one, tested and worked fine. Assembled everything from old screen to new, closed it up, powered on, and touchscreen isn’t working. So tested the old one, and that also didn’t work. Reset via Home/power and still the same. Cleaned with isopropyl and checked for knocked off chips in the area. I have no ideas left, so wondered if you guys have anything else for me? Cheers.
Its almost certainly a bad screen. Yea…I know you put the old one on but its fairly common with iPhone 6 and up that a bad screen can make things wonky. Buy a good screen from a reputable place like iFixit. After you put the new screen on, plug it into power and do a hard reset. The phone should work like new. I’m curious as to how this made it back to the customer if you knew it wasn’t working?
