iPhone 8 Screen Black? Here's Why & The Real Fix!

David Lynch

AUGUST 25, 2017

You're seeing nothing but a black screen on your iPhone 8 and you don't know what to do. This could be caused by your iPhone's software, but there's also a decent chance there's a hardware problem with your device. In this article, I'll explain why your iPhone 8 screen is black, show you how to troubleshoot potential software issues, and recommend repair options if your iPhone 8 is broken.

Software vs. Hardware: Why Is My iPhone 8 Screen Black?

Before we begin, it's important to know that there could be a software or hardware issue making your iPhone 8 screen black.

If the software on your iPhone 8 completely crashed, it can make the screen turn completely black and make it appear as if your iPhone 8 is off. The first in our troubleshooting guide, the hard reset, will help you determine whether or not you're dealing with a software crash.

If the Apple logo doesn't appear after you perform a hard reset, there's probably an issue with your iPhone 8's hardware.

Hardware Issues That Can Cause An iPhone 8 Black Screen

If your iPhone 8 screen is black, there could be a hardware issue with either your iPhone's display or logic board. You probably don't want to try and fix your iPhone on your own because the process can be complicated and it requires a specialized toolkit.

If your iPhone 8 is covered by warranty, your first trip should be to the Apple Store to see if they'll cover the cost of the repair. If your iPhone 8 isn't covered by a warranty, we highly recommend Puls, a service that will come to you and fix your iPhone!

Back Up Your iPhone

It's important to back up your iPhone before doing any major restores (such as a DFU restore). If something goes wrong while you're trying to fix your iPhone, having a back up means you won't lose any of your data (such as contacts, photos, apps, and more). Restoring from a back up is a lot more convenient than having to go and reenter all the information that was saved on your iPhone.

How Do I Back Up My iPhone?

There are a few different ways to back up your iPhone:

Backup Your iPhone Using iCloud

  1. If you have a WiFi connection, you can back up your iPhone using iCloud.
  2. Open the Settings app.
  3. Tap iCloud (I blacked out my iCloud email address in my screenshot, but you'll see your iCloud email address there!)
  4.  Tap Backup.
  5. Make sure the switch next to iCloud Backup is on. You'll know the switch is on when the switch is green.
  6. Tap Back Up Now.
  7. A status bar will appear to tell you how much time is remaining.

Backup Your iPhone Using iTunes

  1. Plug the Lightning connector on your Lightning cable (charging cable) into the Lightning port on your iPhone.
  2. Plug the other end of your Lightning cable into a USB port on your computer.
  3. Open iTunes on your computer.
  4. Click on the iPhone icon in the upper left hand corner of iTunes.
  5. Click the circle next to "iCloud" or "This computer" to select whether you want to backup your iPhone to iCloud or your computer.
  6. Click Back Up Now to backup your iPhone.
  7. When the backup is complete, you'll see the time and date updated under Latest Backup.

Backup Your iPhone Using Finder (Macs Running Catalina 10.15 or newer)

  1. Connect your iPhone to your Mac using a charging cable.
  2. Open Finder.
  3. Click on your iPhone under Locations.
  4. Click the circle next to Back up all of the data on your iPhone to this Mac.
  5. Click Back Up Now.
  6. When the backup is complete, you'll see the time and date updated under Latest Backup.

DFU Restore Your iPhone

A DFU restore has the potential to fix software problems by completely erasing the code which may be causing your problem. The code is rewritten as if  your iPhone is brand new, so the software problem may get solved.

Think of it like a house that has cracks in the foundation. Rather than try and fix the cracks, we are building an entirely new foundation.

If you can, back up your iPhone before completing a DFU restore. Any time you do a restore, it erases everything from your iPhone. However, after the restore is completed, you restore all your backed up data back onto your iPhone.

How Do I DFU Restore My iPhone?

Watch our DFU restore video walkthrough on YouTube, or follow the steps below:

  1. Using a Lightning cable, plug your iPhone into a USB port on your computer.
  2. Open iTunes if you have a PC or Mac running Mojave 10.14 or earlier). Open Finder if you have a Mac running Catalina 10.15 or newer. It doesn’t matter if your iPhone is on or off.
  3. On an iPhone 6s or older, press and hold the Home button and the power button. On an iPhone 7, press and hold the power and volume down button.  
  4. After 8 seconds, release the Power Button, but continue to hold the power button (iPhone 6s or older) the volume down button (iPhone 7).
  5. Let go of the power button or volume down button when your iPhone appears in iTunes or Finder.
  6. Your iPhone’s display will be completely black if you’ve successfully entered DFU mode. If it’s not, try again from the beginning.
  7. Restore your iPhone using iTunes or Finder.

Repair Your iPhone With Apple

Apple repairs iPhones at the Genius Bar in Apple Stores and through their online mail-in repair service. Apple repairs are high-quality, but out-of-warranty repairs can be much more expensive than third-party solutions. If you're looking to save some money you're not covered by Apple's warranty, you may want to check out our other recommendations.

How Do I Repair My iPhone With Apple?

How To Repair Your iPhone With Apple's Mail-In Service

  1. Visit Apple's support website to begin the online mail-in repair process.
  2. Alternatively, call 1-800-MY-APPLE (1-800-692-7753) to set up a repair.

How To Repair Your iPhone At The Genius Bar Inside Your Local Apple Store

  1. Visit Apple's website to make a Genius Bar appointment before you go into the store. Apple Stores are extremely busy, and if you don't have an appointment, you may have to wait for hours or end up being turned away. (Editor's note: I'm a former Apple tech and we're not exaggerating — please, do yourself a favor and make an appointment first!)
  2. When you arrive, go to the Genius Bar to check in for your appointment.
  3. Genius Bar appointments always include free diagnosis. If you're under warranty, many repairs can be done on the spot, but it all depends upon which parts are in stock. If you're not under warranty, the Genius will give you a quote for the cost of a repair.
