Onn Monitor Not Working (How To Fix)

If your ONN monitor isn’t turning on or suddenly stopped working, the primary reason for this is a temporary system glitch or a faulty power supply unit inside the monitor.

Most of the time, you can do nothing except some basic troubleshooting steps.

If performing the following troubleshooting steps revives the monitor, great. But if not, you have to either contact a repairer or buy a new one.

Step 1: Check Power and Cables

Ensure that your monitor is plugged into a working outlet, and make sure the power cable is undamaged and securely connected.

Also, check the cable linking your monitor to your computer or device to ensure it’s properly attached on both ends.

Step 2: Confirm the Right Input

If your monitor has multiple input ports (like VGA, HDMI, or DisplayPort), use the monitor’s buttons or menu to select the correct one.

Look for a button labeled “Input” or “Source” and press it until you see the desired input on the screen.

Step 3: Reboot Your Computer

Restarting your computer can sometimes resolve display issues.

Turn off your computer, wait for 60 seconds, and during this time, press and hold the monitor’s power button for about 10 seconds.

Then, turn on your computer and check if the monitor works.

Step 4: Update Display Drivers

Your display drivers are software that helps your computer communicate with the monitor.

Outdated or corrupted drivers can cause display problems.

Connect your computer to another display, and then use the Windows Update feature or download the latest drivers from the manufacturer’s website to update them.

If these steps don’t work, you may need to contact a repair professional or consider getting a new monitor.
