Phone crashed while testing new screen (no screws installed) iTunes ok
I was replacing a screen assembly on iphone 6. before putting the screws back in I turned the device on and tested it. it was working fine. The digitizer shifted a tiny bit (maybe it pulled a connector off?) but the phone went off entirely. I have not been able to get it back on since. I did try a second brand new replacement screen assembly (known good) and it does the same thing.
I can power on the phone and iTunes DOES see and communicate with it.
I installed the screen again (no home button or any connectors except the screen and digitizer) - powered on, used a flashlight and could NOT see anything on the screen in the dark.
All pins on connectors look good. I dont thinks the backlight filter since I cant see anything with a flashlight.
Any ideas or suggestions. Thanks
