Title: Troubleshooting and Repairing an iPhone 7 Display Issue
Introduction: Hi, I’m Simon. In this video, we’ll troubleshoot an iPhone 7 that has stopped displaying anything on the screen. The phone still functions (receives calls, texts, and charges) but the display remains blank. We’ll explore potential solutions, including reconnecting the battery and LCD screen and potentially replacing the screen.
Troubleshooting Steps:
- Initial Assessment:
- The phone functions normally but has no display.
- The aim is to try disconnecting and reconnecting the battery and LCD screen to see if this resolves the issue.
- Opening the iPhone:
- Use a 0.8 Torx screwdriver to remove the two screws at the bottom of the iPhone.
- Gently pry open the screen using a metal prying tool to cut through the adhesive.
- Open the screen to a 90-degree angle and use a Tri screwdriver to remove internal screws.
- Disconnecting the Battery and Screen:
- Disconnect the battery and the two cables connected to the LCD screen.
- Reconnect them to see if the display issue resolves.
- Testing with a New Screen:
- If the display still doesn’t work, test with a new LCD screen to diagnose whether the issue is with the original screen.
- Replacing the Screen:
- If the new screen works, proceed to replace the old screen.
- Carefully transfer the front speaker, camera, and home button to the new screen.
- Ensure all connections are secure and reassemble the iPhone.
- Reassembling the iPhone:
- Align and press the screen back into place, starting from the top.
- Replace the screws at the bottom of the iPhone.
