Monitor Not Turning On [Proven & You Should Try This First]

1- Check Power Cable

To determine why a monitor is not turning on, first check the power cable. If the monitor has a surge protector connected to it, ensure that it is properly plugged in. 

If the monitor is directly connected to an outlet, check if the cord has come loose from either the monitor or wall socket. 

In addition, inspect both ends of the cord for wear and tear even if there is no power supply issue. 

Try replacing it with a new power cable if there are still any issues or else just buy a new one instead.

Checking that the monitor is properly connected to a power source should be the primary step in troubleshooting monitor issues. 

Worn or broken power cords can cause problems ranging from monitor flickering to complete shutdown. 

If there are signs of damage on the cord, such as fraying or exposed wire, then it should be replaced immediately. 

Once a new power cable has been connected, the monitor should turn back on without any problems.

2- Check HDMI Cable

A faulty or damaged HDMI cable can cause the monitor not to turn on. 

If your monitor is not turning on, check if it is an old and damaged HDMI cable that could be causing the problem by seeing whether it works correctly. 

To diagnose this issue, checking if the HDMI cable functions as intended is one of the best ways forward. 

Replacing a broken or faulty HDMI cable with a new one should help solve this issue provided there are no other problems such as loose cables or power issues present before doing so. 

It is important to check if all settings on your monitor are correct and if there aren’t any other issues prior to replacing the HDMI cable. 

It might just be another problem with loose cables or power that needs fixing first instead of replacing the cable which may fix nothing.

In case there isn’t anything wrong with other things such as settings and cables before replacing it since doing so would only waste money in case everything else checks out fine.

3- Check Power Socket

If your monitor is not turning on, it may be because of the power socket. 

If your power socket is damaged or worn out due to too much usage, it could cause a spark when you plug in the monitor which would then disrupt the flow of current.

You can fix your monitor problem that is not turning on by replacing old power socket with the new one. 

If the problem is persist even after replacing the power socket, it is best to check power supply. 

Additionally, if the wiring connected to the monitor is loose or if the power cord has been damaged, this could also prevent the monitor from turning on. 

In either case, if you find yourself with an unresponsive monitor, it is important to diagnose the cause and take the proper steps to get your monitor back up and running.

4- Faulty Power Supply

If your computer monitor is not turning on, it could be because of a faulty power supply. 

Signs of an issue with the power supply include flickering or dimming of the screen, no output from the monitor, or unexpected shutdowns. 

If you are experiencing any of these technical difficulties, replacement of the power supply is advisable. 

It is important to diagnose the exact problem first before attempting to replace it. 

If your monitor does not turn on at all in spite of plugged-in status, there might be other problems such as a broken cable or internal malfunction within the monitor itself. 

To find out if a faulty power supply is preventing your computer screen from powering up properly, look for signs around the plug and outlet area that may indicate overheating. 

If unusual noises come from your computer when it’s plugged in and this continues even after resetting it several times then this could mean there’s an issue with its PSU (power supply unit).

Once you have determined that it is indeed a faulty power supply causing your monitor not to turn on, you can then replace it with one that is compatible.

5- Update Monitor Driver

In case your monitor isn’t turning on, one of the steps you can follow to troubleshoot it is by updating the monitor driver.


Updating a monitor driver may be necessary if you are facing issues like flickering or incorrect resolution on your screen. 

You can check for updated drivers manually by downloading them from the manufacturer’s website. 

If you aren’t sure whether there is an updated version of the driver or not, you can check in Device Manager in Windows and look for your monitor device in the list of hardware devices. 

If there is an exclamation mark next to your device’s name, this indicates that there is a problem with its driver and it needs to be updated. 

Keeping up-to-date with monitor drivers helps improve operation and performance as well as prevent instances where it doesn’t turn on correctly in future.

Updating your monitor driver is essential for making sure everything runs smoothly on your system.

6- Check Monitor Adaptor

Checking the monitor’s adaptor is a crucial step when troubleshooting monitor power issues. 

First, make sure the monitor is securely plugged into an electrical outlet with its adaptor and that the power switch on the monitor has been turned on. 

If the monitor does not turn on after ensuring it is properly connected to a power source, check whether the monitor’s indicator light is illuminated. 

If there is no light, it could indicate a faulty monitor adaptor or a damaged power cord. 

Additionally, make sure that any surge protectors or extension cords are functioning properly and are not defective. 

Lastly, inspect the monitor’s adaptor to ensure its pins are intact and free of corrosion.

7- Monitor’s Backlight is Faulty

Whenever you are facing a problem with your monitor not turning on, it is likely that the monitor’s backlight is faulty. 

In cases when the backlight fails to lighten up its screen and make it easy or possible to see what’s on the monitor.

It can occur due to many problems including a loose power cable, dead inverter board, faulty circuit board, aging backlights or any other issue. 

One of the simplest ways to identify if the problem is with your monitors’ backlight is by connecting them to another computer and attempting to turn them on. 

If nothing appears after doing this then you will know that your monitors’ backlights have failed. 

To fix this issue you might need to replace either the power cord of your monitor or its inverter board or even its backlights depending on what may be causing the problem. 

It’s important to remember that in some cases replacing any of these components might be quite costly and maybe not worth fixing at all.

8- Old Graphics Card

If your monitor is not turning on, it may be a problem with your graphics card. 

If you have an older graphics card that isn’t compatible with the monitor, this could lead to the monitor not starting up. 

Older graphics cards may no longer be supported by monitor manufacturers, so they will likely not be able to recognize the device when it is connected. 

To troubleshoot if this is causing your monitor not to turn on, try connecting it to another display and see if it works. 

If it does work then this issue most likely has something to do with your graphics-card compatibility. 

If you have current hardware, check that all of the cables connecting everything are securely plugged in and that all settings match correctly.

9- Faulty Motherboard

When there is a problem in the monitor not turning on, it may be caused by a malfunctioning motherboard. 

In some cases, the monitor may still receive power but the internal circuitry of the monitor is failing to initiate a proper boot due to broken or outdated components such as capacitors, resistors, and transistors. 

As these parts age, they become less efficient and can cause the monitor to be unresponsive or fail to turn on.

To troubleshoot this issue, make sure that your monitor is plugged into a functional source of power and that all cables are properly connected. 

If these steps do not solve the issue, then it’s likely that some of your internal monitor components need to be replaced. 

If you are not comfortable or familiar with electronics repair work, it is best advised that you seek professional assistance for help.
