How to fix Black Screen issue on OnePlus 6

Is your OnePlus 6 not working and only showing a black screen? This short troubleshooting article will show you the things that you can do to figure out what’s causing it.

Troubleshooting Black Screen issue on OnePlus 6

Discoloration, unnatural lines, and unresponsiveness are usually signs of screen malfunction. In many cases, repair is the least that can be done. In some few cases though, black screen may be temporary and a result of a minor bug. To find out whether or not the black screen issue on your OnePlus 6 device is fixable, check out our suggestions below.

Simulate a battery disconnect (forced reboot)

Some OnePlus 6 users may interpret a frozen or unresponsive device as a bad screen problem right away. To check if your OnePlus 6 has simply become unresponsive to touches, try to force reboot it with these steps:

  1. Press and hold down the Power button on the right side of the phone
  2. Hold the Power button down for 10-12 seconds, or until the phone vibrates and restarts
  3. If the phone turns off let go then press power again for 1-2 seconds to restart the phone

If your screen works briefly after doing the steps above and shows that the device is restarting, this should be the easy fix. If there’s no response at all, or if the screen stays black, proceed to the next troubleshooting step.

Check for signs of life

In some cases, having a black screen can be an indication that the device is completely unresponsive or dead. This can spring from a number of causes. However, if your OnePlus 6 screen stays black but the phone still makes a sound, vibrates, or has visible LED light, that means that the problem may only be isolated to the screen assembly. This usually occurs after an accidental drop and the screen is broken or permanently damaged. If the phone is not totally unresponsive as mentioned, you should forget doing the rest of the troubleshooting steps below and instead send the phone in. There’s no software solution that can fix a physically broken screen.

Charge using another set of accessories

Sometimes, black screen may result from certain charging issues. Try to charge the phone using another set of cable and adapter to see if that will power up the battery faster. If there’s no physical damage to the screen, this may help fix your trouble.

Clear cache partition

This troubleshooting step is only applicable if the screen was not physically damaged. By clearing the cache partition, we assume that the cause may be related to the system cache. You should only try this option if your OnePlus 6 was working normally but suddenly showed the black screen.

  1. Turn your phone off by pressing down the power key for five seconds. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the volume key and the power button simultaneously until the device vibrates and opens the Recovery menu.
  3. Choose your preferred language.
  4. Using the volume keys to navigate, go to Wipe > Wipe cache > Yes to start the process
  5. Reboot the device after this is done.

Hard reset

Like with the previous option above, hard reset should only help if there’s a software-related bug behind the trouble. If your device was working properly before and you did nothing differently, it’s possible that an unknown software or firmware bug has developed that resulting to the screen glitching. Again, don’t waste your time attempting a hard reset if you know for a fact that you dropped the phone or got it wet before the screen turned black.

To hard reset your OnePlus 6:

  1. Turn your phone off by pressing down the power key for five seconds. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the volume key and power button simultaneously until the device vibrates and opens the Recovery menu.
  3. Choose your preferred language.
  4. Using the volume keys to navigate, go to Wipe > data cache > Erase everything > Confirm.
  5. Reboot the device after this is done.

Get professional help

This one is the last thing that you can do if no software troubleshooting has helped fix the problem. Remember, there’s only so much that an end user like you can do. If your OnePlus 6 screen became black out of the blue, or if your phone got banged up, you should have it checked by a trained technician so you’ll get accurate information on what to do next. If you’re lucky and the physical damage is only isolated to the screen, replacing the screen assembly might be enough to revive it.
