My wife dropped her phone on Sunday... I don't want to replace the screen if it's the logic board and nothing can be done to recover her data. A beautiful picture:

Plaid Phone

If this were the 1970's her phone would be so vogue... Who didn't love plaid back then?

Anyway... I have taken the screen off and checked the connections, put everything back together. No change.

  • The phone still rings when called
  • The phone vibrates when switched into silent mode
  • The digitizer is not working - the phone cannot be "unlocked" and calls cannot be answered
  • There was a screw that had detached from the retaining plate where the screen connects to the logic board
    • Loose Screw
  • I tried hard reboots (power + home)
    • The home and power buttons are still recognized but this has no impact on the artifacting display
    • During the hard reboot the display goes blank and then lights up again after being restarted.
  • I tried disconnecting / reconnecting the battery from the logic board
    • This had no impact on the display. We've gone plaid.

Curious if anyone can tell whether this symptom is indicative of a bad logic board or if the display / digitizer cables have been damaged!

If your phone rings when called, that tells you a couple things that the phone is able to do:

  • The phone is able to turn on.
  • The phone is able to process the received call (and I'm guessing all of iOS's pretty effects with loading it as well).
  • The phone is able to process events from all of the phone's physical buttons (the Lock button, Volume Up/Down, and the Home button).

However, as it seems, the phone isn't able to send touch events to the UI, meaning the digitizer is broken.

Screw in the loose screw, replace the screen/digitizer unit, and reboot. All will be well. :)

  • Excellent! Thank you for your take on it! I have ordered the part and will respond with my findings :)
