My phone turns on and appears to be fully functional however the display does not now work. Connected to power, the phone vibrates and makes the chime sound. I even heard a notification come through. The home button also works. The repair went smoothly apart from reassembling the cover that protects the display, battery and wifi cables. I got the screws mixed up (who knew orange and red were so similar?). Is it possible this is the reason for my display not working?
Open it back up and inspect the display cables for any tears or creases but if you got the screws mixed up, there’s a chance you caused long screw damage to the board and that’s something only a skilled microsoldering specialist can handle.
