ONN TV Not Turning On: Basic Troubleshooting Steps

Experiencing an ONN TV black screen can be a common yet solvable issue. If you find yourself asking, “Why is my ONN TV screen black?” or if your ONN TV is not turning on properly, these initial steps can help you identify and possibly resolve the problem.

1. Power Cycle the TV

If your ONN TV screen is black or the TV isn’t turning on, the first and simplest step is to perform a power cycle. This process can reset the TV’s internal systems, often resolving minor glitches. To power cycle your ONN TV:

  • Turn the TV off completely.
  • Unplug it from the wall socket.
  • Wait for at least 30 seconds before reconnecting the power.
  • Turn the TV back on and check if the black screen issue persists.

2. Check and Secure All Cables

Loose or damaged cables are a frequent culprit when your ONN TV has no picture or displays a black screen. Follow these steps to ensure all connections are secure:

  • Inspect the power cable to ensure it’s firmly connected to both the TV and the power outlet.
  • Check all HDMI and other input cables for secure connections.
  • Examine the cables for any visible signs of damage. If you find any, replace them with new ones.
  • Once all cables are checked and properly connected, turn on your TV to see if the issue is resolved.

These basic steps are often effective in solving the ONN TV black screen issue. If your ONN TV screen remains black or if there’s no picture after trying these methods, further troubleshooting may be necessary.

How To Fix ONN TV Black Screen?

When basic methods don’t resolve the ONN TV black screen issue, it’s time to delve into more advanced troubleshooting techniques. These steps can be particularly helpful if you’re still wondering, “Why is my ONN TV screen black?” or if your ONN TV has no picture but seems to be powered on.

1. Checking Input Settings

A common reason for an ONN TV screen being black is incorrect input settings. This can happen easily, so verifying your TV’s input is a crucial step:

  • Use the remote to navigate to the input settings on your ONN TV.
  • Cycle through the different inputs to ensure the TV is set to the correct source (HDMI, AV, etc.).
  • If you’ve recently connected a new device, double-check that it’s linked to the right input.

2. Remote Control Inspection

Sometimes the issue of an ONN TV not turning on or displaying a black screen can stem from a faulty remote control:

  • Check the remote for any physical damage.
  • Replace the batteries if they haven’t been changed in a while. Weak batteries can cause signal issues.
  • Test the remote’s functionality, ensuring it properly communicates with the TV.

3. Disabling Sleep Timer (For Roku TVs)

If your ONN TV is a Roku model and the screen goes black unexpectedly, the sleep timer might be activated:

  • Access the settings menu using your Roku remote.
  • Navigate to the ‘System’ settings, then to ‘Time.’
  • Check if the sleep timer is on, and if so, disable it.
  • Monitor the TV to see if the black screen issue reoccurs.

4. Using Set Keybind for Roku TVs

For those with a Roku model of ONN TV, a set keybind can be a swift solution for a black screen. This method allows you to restart the TV without needing to access the visual menu, which is particularly useful when dealing with an ONN TV black screen.

  • Press the ‘Home’ key on your remote five times.
  • Press the ‘Up’ arrow key once.
  • Then, press ‘Rewind’ twice and ‘Fast Forward’ twice.

5. Plug into a Different Power Outlet

Sometimes, power issues can cause your ONN TV screen to remain black. Try plugging your TV into a different outlet. Ensure the outlet delivers sufficient power and isn’t overloaded with multiple devices.

6. Backlight Inspection

If your ONN TV screen is black but you can hear sound, the issue might be with the backlight. To test this, shine a flashlight at an angle close to the screen. If you can see images with the help of the flashlight, the backlight likely needs replacement.

7. Factory Reset

A factory reset will restore your ONN TV to its original settings. To perform a factory reset, follow these steps:

  • Locate the Reset Button: Find the reset button on your ONN TV. This is usually a small pinhole labeled ‘reset’, often located on the back or side of the TV.
  • Initiate the Reset: Using a non-metallic, pointed object (like a paperclip), gently press and hold the reset button. Continue to hold for 10-15 seconds.
  • Wait for the Restart: Release the reset button. The TV will automatically restart. This process may take a few minutes.
  • Setup Post-Reset: After the TV restarts, you will need to go through the initial setup process, just as you did when you first purchased the TV. This includes tuning channels, connecting to Wi-Fi, and adjusting settings to your preference.

8. Hard Reset

A hard reset is another method to potentially fix the ONN TV black screen issue, especially if the TV is not responding to the remote control or has other power-related problems.

  • Turn Off and Unplug the TV: Ensure that your ONN TV is turned off. Then, disconnect it from the power source completely.
  • Drain Residual Power: Press and hold the power button on the TV itself (not the remote) for about 30 seconds. This step helps to drain any remaining power in the TV’s capacitors.
  • Reconnect and Power On: After 30 seconds, release the power button, reconnect the TV to the power source, and turn it on.


Navigating the challenge of an ONN TV black screen can be frustrating, but with the comprehensive troubleshooting steps outlined in this guide, most issues can be resolved effectively at home. From simple fixes like power cycling and checking cables to more advanced techniques like factory resets, these methods are designed to bring your ONN TV back to life. However, it’s important to recognize when a problem is beyond a DIY fix. If you’ve diligently followed these steps without success, it’s prudent to reach out to ONN customer support for specialized assistance.
