Troubleshooting a MacBook Black Screen: Causes and Solutions

If you’ve ever booted up your MacBook and found it unresponsive, with a black or white screen, or nothing on the screen at all, don’t panic. It’s possible to solve the issue without the need for a costly repair. In this tutorial, we’ll guide you through the troubleshooting process to identify and fix the problem.

First Steps

Before diving into the more time-consuming solutions, let’s cover some troubleshooting basics. Make sure to:

• Reset the PRAM or NVRAM
• Reset the System Management Controller
• Triage: try to identify the problem by asking yourself questions like “Did I recently update my software?” or “Did I spill something on my laptop?”

These simple steps can help you identify the root cause of the issue.

Buggy Software

Software issues can cause a black screen on your MacBook. Data corruption or software flaws can result in unexpected behavior, including a blank display. Try:

• Launching into Safe Mode
• Repairing the file system using Disk Utility
• Using Internet Recovery to reinstall macOS
• Creating a bootable USB installer

If you’re still experiencing issues, it’s possible that the problem lies with your firmware.

Firmware Corruption

If your Mac is from 2018 or newer, it’s possible that it encountered an error or lost power during a firmware update. Try:

• Using Direct Firmware Upgrade (DFU) mode to diagnose or solve the issue
• Reinstalling the operating system using Internet Recovery

Damaged or Faulty Display

Visible damage to your display can cause a black screen. Even without damage, internal faults can prevent the display from working properly. Check for:

• Visible damage to the display
• Internal faults, such as a faulty backlight or LCD panel

Faulty Flex Cables

The flex cables connecting the logic board to the display can cause issues. Check for:

• Damage to the flex cables
• Apple’s Repair Program for 13″ 2016 MacBook Pro models

Faulty Internal Display Cable

The cable connecting the logic board to the display can be a rare fault. Check for:

• Damage to the eDP or LVDS cable

Faulty Hall Sensors

The hall sensors that detect the laptop’s lid position can fail. Check for:

• Failure of the hall sensors
