An Onn monitor can stop working if the power supply is insufficient, the power cable is malfunctioning, or the CPU sends an enormous amount of resolution that the monitor can’t handle.
Anything could be the culprit.
In most cases, you can simply fix this by power cycling. However, if power cycling doesn’t work, you may need to perform some robust troubleshooting.
Well, let’s dive in and find out how to fix your Onn monitor that is not turning on or showing no signal!
Why does my Onn monitor isn’t working?
I already mentioned this!
If your Onn monitor isn’t turning on, it could be due to a faulty power supply, insufficient power reaching the monitor, a malfunctioning display panel, or a burned-out internal circuit.
One more thing!
If the monitor turns on, but you only get a ‘No signal’ message, then the video cable may be loose, the input port or the graphics card might be malfunctioning, or it’s even possible that the resolution is higher than the monitor’s capacity!
Anyway, here’s a list of some general rules:
- Power source issue.
- Compatibility issues.
- Connection issues.
- Issues with the monitor itself.
How to Fix ONN Monitor Not Working?
- Disconnect the monitor from the power source completely.
- Disconnect all the cables connected to the monitor as well.
- Wait for at least 60 seconds.
- Dusing this time, press and hold the power button for about 15 seconds.
- Once done, power the monitor back on and test the result.
Here are the detailed step-by-step guidelines:
Step 1: Power Check
Our first stop is the basics.
Make sure that everything is plugged in correctly. Check the power cable, and even try plugging it into a different outlet.
Sometimes the simplest solutions can save the day.
I once spent an hour troubleshooting my monitor only to realize that the outlet I was using had a blown fuse!😁
Step 2: Visual Inspection
Examine the monitor for any obvious signs of damage or lose connections.
Make sure it’s properly connected to your computer, too.
You can try using a different video cable, like HDMI or DisplayPort, to make sure the problem isn’t cable-related.
Step 3: Test a Different Display
In order to determine if the issue lies with your monitor or your computer, connect a different display to the computer.
If the issue persists on the new screen, the culprit might be your computer’s graphics card.
If you’re unsure how to troubleshoot that, a quick Google search will lead to an abundance of advice from tech-savvy gurus.
Step 4: Monitor Menu Magic
If the monitor displays the startup logo but stays blank thereafter, try accessing the monitor’s “On-Screen Display” (OSD) menu by pressing the Menu button.
If you can see the menu, great news! It’s likely that your computer or video cable is the guilty party here.
I once tinkered with the OSD settings on an old monitor without paying attention, and when I connected it back to my computer, it remained stubbornly blank. Little did I realize my fiddling had resulted in a nonexistent resolution and refresh rate! Needless to say, I’m now very careful when experimenting with OSD menus.
But, alas, if your efforts have not borne fruit, it may be time to accept defeat and consider a replacement.
In that case, think of this as an opportunity to search for a shiny new monitor that suits your needs even better.
Onn monitor no signal
Check the cable connections between the monitor and your computer. Ensure that the input source on the monitor matches the connection you are using (e.g., HDMI, VGA, etc.). If the problem persists, try a different cable or port on your computer.
Here are some more things you may want to try:
1. Check that your monitor is properly connected to your computer. Make sure that the cable is securely plugged into both the monitor and the computer.
2. Check that your computer is turned on and that it is not in sleep mode or hibernation. If it is, try waking it up by pressing a key on your keyboard or moving your mouse.
3. If you have multiple inputs on your monitor, make sure that you have selected the correct input. You can usually do this by pressing a button on your monitor or using the on-screen menu.
If the problem still persist, you need to disassemble the CPU and then clean the RAM slot.
