I replaced the lcd of my screen , it’s on i can hear phone calls etc, when I plug it into the computer the computer doesn’t bring up iTunes or any notification. also during repairing the lcd I forgot to disable the battery and at the moment the power button doesn’t work so I can’t do a hard reset
See if you can see anything on the screen with a flashlight on it after you wa kn e up the phone. It would also help if it was a dark room. There its possible that you blew a couple of back light filters because you disconnect the battery.
