How to Fix an Onn TV Black Screen (Easy Fix)

Onn TVs are a popular choice for people looking for affordable, high-quality televisions. However, like any electronic device, Onn TVs can sometimes encounter problems. One common issue that users experience is a black screen.

If you’re dealing with this problem, don’t worry – there are several things you can try to fix it. In this article, we’ll go over some steps you can take to get your Onn TV back up and running.

Performing a Restart on the Device

There are several techniques you can take to address the black screen on your Onn television. In most circumstances, simply restarting the television is the simplest option.

There are several methods for mending a black screen on an Onn TV. These can be as basic as turning off and then turning back on the television. Fixing the backlighting may be an option, albeit it’ll be more difficult to execute.

Turn Off the TV and Then Back On

The quickest and easiest solution would be to turn off the television and then turn it back on. Despite the fact that identifying the root cause of this problem is more difficult, the solution offered here is successful.

In most circumstances, it’ll bypass the earlier “bug,” allowing you to continue enjoying your evening without interruption.

Wait Until You Turn Off the Television

If the first option you try does not work, don’t give up. After unplugging your television, turn it off and wait at least one minute. When you plug the TV back in, it should quickly restore to the most recent factory default configuration and resume regular operation.

Personally, I found this method to be effective. If it doesn’t work for any reason, do it again, but this time wait fifteen to thirty minutes before turning on the television.

TV Settings

Changing the Settings on Your TV Putting your TV into sleep mode or using a TV sleep timer could also be the source of your problem. By simply switching the settings to the off position, you should be able to return your TV screen to its normal state and have it ready for viewing in no time.

Another common problem is with the remote, which may also need to be reset in some situations. You must do the following to accomplish this:

  • Please remove the batteries (discard and replace them if you’re unsure that these work)
  • Keep your finger on the “power” button for one minute.
  • It’s time to replace the batteries.
  • Try again to gain access to the television.

If none of these suggested solutions have worked so far, you may need to look into more underlying issues. Don’t worry, we’ve got you covered with extra technical solutions you can address from the comfort of your own home.

Some issues and their explanation

There are occasions when restarting just does not work. When something like this happens, you should look at a variety of possibilities.

Upgrade or Update of Software

The next step in the TV repair procedure is to address the software’s capacity to receive updates.

The Roku operating system serves as the backbone for the platform used by Onn TVs. Roku‘s online community support site has acknowledged that black screens are a very common issue and has supplied a website, a phone number, and a link for consumers to acquire software upgrades in response:

  • Software Update Procedures
  • Onn’s Support Website 
  • Contact Onn’s Customer Service at 1-844-334-235. 

You’ll have no trouble finding someone to answer your Onn TV questions.

Restoring Default Settings

If all of your previous efforts have been futile, you can try a factory reset. To complete this procedure, locate the “Reset” button on the back of the television. 

Maintain your finger on the button for at least 20 seconds. When you delete your cloud storage, you’ll lose all of your personal data, including the login details for your streaming accounts. Can’t seem to find the reset button? This video will give you extra guidance.


Backlights such as this are used behind TVs for lighting

The hardware is the source of the remaining worries. If the standby light illuminates when you turn on the television, you may have an issue with the backlighting.

Another technique to validate this notion is to shine a flashlight on the television. If you can see the images that are hidden inside, you’ll know there’s a problem with the backlighting.

The Power Source

It’s conceivable that you’re having power supply issues right now. This happens when the television is hooked into an outlet but does not get electricity. Again, self-diagnosis and self-treatment are valid possibilities. 

If you connect to the computer’s motherboard, you’ll be able to detect the flow of electricity that is being sent to the TV.

Black Screen Fix


What Should You Do if Your TV Goes on But the Screen Is Black?

Replace the HDMI cable if it has a short or any flaw that is causing the black screen. For five minutes, unplug the TV to attempt a reset.

To do a soft reset, unplug the TV from the wall and, if possible, take the power cord out of the TV’s back. To test the TV once more, wait 30 seconds and plug it back into a functional outlet.

Why Isn’t Onn TV Working?

Unplug your ONN TV from the outlet and turn it off for a few minutes. Then, reconnect your TV and check to see if it connects to your Wi-Fi.

If your Onn TV still isn’t working, it could be due to a loose cable, a power issue, incorrect input settings, outdated software, or even a problem with the TV’s hardware. By taking some troubleshooting steps, such as checking cables, resetting the TV, or updating the software, you may be able to fix the issue. If you’re still having problems, it’s best to contact Onn customer support for further assistance.

Is it Possible to Repair a Television if the Screen Goes Black?

Whether or not it’s possible to repair a television when the screen goes black depends on the root cause of the problem. In some cases, the issue may be related to loose or faulty cables, outdated software, or incorrect settings, which can be fixed by performing simple troubleshooting steps.

However, if the issue is related to the TV’s hardware, such as a damaged backlight or broken panel, it may not be repairable and you may need to replace the TV or the damaged part.


  • The first step to troubleshooting a black screen on your Onn TV is to check the power. Ensure that the TV is plugged in and that the power outlet is working.
  • Sometimes a black screen on your Onn TV can be caused by loose or faulty cables. Check all the cables connected to your TV to make sure they are plugged in tightly and securely.
  • If checking the power and cables doesn’t work, try resetting the TV. Unplug the TV from the power outlet for at least one minute, then plug it back in and turn it on.
  • Make sure that the TV is set to the correct input source. Use the remote to switch between input sources until you find the one that’s connected to your device.
  • If the issue persists, check if there’s an available software update for your Onn TV.
  • If none of the above steps work, the issue may be with the TV’s hardware, and you may need to contact Onn customer support for further assistance.
