Acer Monitor Not Turning On (Fix)

Common Reasons an Acer Monitor Won’t Turn On

There are a few common reasons why your Acer monitor won’t turn on:

1. Insufficient Power Supply

Cause: If your Acer monitor is not getting sufficient power, it will not turn on. This might be due to a faulty power cable, a damaged power outlet, or problems with the monitor’s internal power supply.

Solution: Ensure your power cable is securely connected and in good condition. Try using a different power cable or outlet.

If your monitor still doesn’t turn on, you may need professional help to fix or replace the internal power supply.

2. Incorrect Display Settings

Cause: Sometimes, incorrect display settings may cause your monitor not to turn on or display anything.

Solution: If you’re using a Windows computer, try booting in safe mode.

This can help reset the display settings to defaults and may resolve the problem.

For Mac users, boot into Safe Boot to reset the display settings.

3. Hardware Issues

Cause: In some cases, the problem could be a hardware malfunction. This could include issues with the monitor or your PC’s graphics card.

Solution: Check with a different monitor or computer to identify if the issue is with the monitor or the computer.

You may need to update or replace your graphics card if it’s a computer issue.

If the problem persists with your Acer monitor, a professional service may be required.

4. Power Cable

Ensure the power cable is securely plugged into the back of the monitor and a working electrical outlet.

Unplug it and plug it back in to reseat the connection.

5. Power Button

Check that the power button on your monitor is working properly by pressing it.

If it’s loose or stuck, that could prevent your monitor from powering on.

6. Input Source

Your monitor may not turn on if it’s not set to the correct input source for your computer.

Ensure it’s set to your input source, like HDMI, DisplayPort, etc.

7. Outdated Drivers

Outdated, corrupt or missing drivers can prevent your Acer monitor from turning on properly.

Update your graphics drivers to the latest available version.

8. Faulty Capacitors

If the capacitors on the power supply board of your monitor have failed, this can stop your monitor from turning on.

This requires repair by a professional.

Follow these troubleshooting steps to get your Acer monitor working again:

  1. Check the power cable: Make sure the power cable is firmly connected to the monitor and wall outlet. Unplug and plug it back in. Try a different power cable if possible.
