If your iPhone falls or suffers liquid damage, you may notice that the device is showing colored vertical lines on the screen. This will often occur on older iPhone models although it has been seen on newer devices as well. In this article, we are going to look at exactly why those vertical lines appear on the iPhone screen and what you can do to fix this issue.
This problem usually occurs soon after a device falls since the iPhone's LCD cable gets disconnected from the logic board. Sometimes even if you didn't drop the device, a software problem can also cause the iPhone to show vertical lines on the screen.
Before we get to the possible solutions for this problem, it is important to back up all the data on the iPhone to avoid data loss during the repair. Even if the device is seriously damaged, you may still be able to backup all data on it. We recommend using iTunes or iCloud to back up the iPhone. You will need the device's lightning cable if you choose to backup via iTunes. But if you choose to use iCloud, ensure that you have adequate iCloud storage for all the data on the device. Besides, you can use third-party tool like FoneGeek Backup & Restore (iOS) to do the backup without iTunes or iCloud.
The best solution to eliminate the vertical lines appearing on your iPhone screen, especially if there is no physical damage to the device, is using FoneGeek iOS System Recovery tool. It is an ideal tool to help fix all kinds of software related issues on your iOS device. Some of the program's features include the following:
Here's how to use FoneGeek iOS Repair tool to fix iPhone vertical lines issue:
Step 1: Install FoneGeek on your computer and then launch the program. Connect the iPhone to the computer using USB cables and unlock it to allow the program detect the device.
Step 2: On the main window, select "Repair Operating System" to begin the process. FoneGeek will detect the device and provide the necessary firmware. Click "Download" to download the corresponding firmware.
Step 3: FoneGeek will begin repairing the device. Keep it connected until the process is complete.
Most users have reported that the program works very well to fix the iPhone with vertical lines. But if the above procedure doesn't work for you, try using the deep repair mode.
Try the following basic solutions to help you repair the lines across iPhone screen issue:
A force restart is another great solution to help you repair an iPhone that is showing vertical lines. Here's how to force restart the iPhone;
For iPhone X and newer versions - Press the side (power) button and one of the volume buttons until the turn off slider appears. Drag it to turn off the device and then press the side button again to restart the device.
For iPhone 8 or earlier - press and hold the top (side) button until the slider appears. Drag the slider to turn off the device and then press the power button again to turn on the device.
A Device Firmware Update (DFU) restore is one of the best ways to repair an iPhone that is no working correctly. DFU will erase the device and restore it to its factory settings, so remember to back up the data on the device. To restore the iPhone in DFU mode, follow these simple steps;
Connect the iPhone to the computer and then open iTunes.
Now press the power and the home button (for iPhone 6 and below) or power button and volume down button (for iPhone 7 or later) for about 8 seconds.
Let go of the power button but continue holding the home/volume down button until iTunes displays the message "iTunes has detected and iPhone in recovery mode".
Release the button and the screen should turn black. You can now restore the device in iTunes which should fix the device.
Resetting the iPhone is another great way to repair iPhone showing vertical lines on the screen. Here's how to do it;
Open settings on your iPhone and tap General.
Tap "Reset" and then select "Erase all Contents and Settings".
You may need to enter your passcode to confirm the action.
After the device is erased set it up again and hopefully the lines should be gone.
Restoring the iPhone in iTunes can also fix a device displaying vertical lines. Here's how to do it;
Open iTunes on your computer and connect the iPhone to the computer.
When the device appears in iTunes, select it and in the summary panel, select "Restore".
Click "Restore" again to confirm the action. Your device will be erased and the iTunes will install the latest version of iOS.
If this issue occurred soon after the device fell, it is possible the LCD cable has disconnected from the logic board. In this case, you can try pushing firmly down on the screen to re-establish the connection. To do this place one finger on the screen and the other on the other side of the device and press down firmly, but be careful not to break the device.
Once the pins connecting the LCD cables to the logic board screen are in place, the lines on the screen will disappear and the display should look normal.
The only thing you can do when all the solutions above don't work is to get the device repaired. Because the device is broken, your warranty may already be voided. But if you have Apple Care Plus, you might be able to get the device repaired relatively cheaply although it may take a while to get it fixed.
The above solutions can all be very useful to help you repair an iPhone that shows vertical lines on the screen. We recommend selecting a solution that you can trust to work on your device depending on the causes and follow the instructions to repair the device. As always, we love to hear from you.
