Preliminary Checks

Before diving into complex troubleshooting steps, it’s essential to start with some basic checks. Oftentimes, seemingly major issues can be resolved with simple solutions. Here’s what you should do:

Check the Power Source and Cables:

    • Ensure that your ONN monitor is properly plugged into a functional power outlet.
    • Examine the power cable for any visible damage or fraying.
    • Confirm that the power cable is securely connected to both the monitor and the power source.

Verify Connections to the Computer or Other Devices:

    • If you’re using the monitor with a computer, make sure the cable connecting the monitor to the computer (VGA, HDMI, DisplayPort) is properly connected at both ends.
    • If you have multiple input options on the monitor, double-check that you’ve selected the correct input source.

Test with Another Device:

    • If possible, connect the ONN monitor to a different device, such as a laptop or gaming console.

Inspect for Visible Physical Damage:

    • Carefully examine the monitor’s screen, bezel, and body for any signs of physical damage.
    • Look for cracks, dents, or other issues that might be affecting the monitor’s functionality.

By conducting these preliminary checks, you can rule out simple causes of the problem and potentially identify the root cause of the issue. If the problem persists after these checks, don’t worry; there are more advanced troubleshooting steps you can take to get your ONN monitor back on track.
