1- Power Connection is Loose

If your ASUS monitor is not turning on, the problem might be due to a loose power connection. This could be because of a loose cable or an issue with the power outlet.

Make sure it is firmly connected to both your ASUS Monitor and the wall outlet. 

If this persists as an issue, you should try a different wall outlet or check if any other electrical devices are functioning properly in that specific wall outlet. 

Additionally, make sure that both your ASUS Monitor and the power outlet are powered on before checking further troubleshooting steps.

2- Check Power Cable

As a part of troubleshooting, if your ASUS monitor is not turning on, you must check the condition of the power cable first. 

You need to make sure that the power cord is firmly connected to both the wall outlet and your ASUS monitor. 

Also, it is essential that you examine if the wall outlet works by plugging in another device like a lamp or hair dryer before attempting any further steps.

To restart your ASUS monitor, press and hold down the power button for at least ten seconds until you see the ASUS logo appear onscreen. 

If even after resetting there are no signs of life from your ASUS monitor then perhaps you need to check its compatibility with your computer.

3- Check Power Socket

If your ASUS monitor is not turning on, the most critical step is to check the power socket. 

Ensure that the monitor is securely plugged into a functioning power outlet; additionally, all cables should be properly connected and secure.

If you are using a monitor with its own separate power adapter plugged in, you must also ensure that it is properly connected and working correctly.

4- Faulty Power Supply

An ASUS monitor is often faced with power supply issues when it does not turn on.

If you suspect the fault to be in the power supply, you may have to replace the entire unit or just replace the cord that connects it to your monitor. 

It’s essential also to check if there are no obstructions between your power source and your monitor that might be causing issues. 

If there have been no issues in connecting your ASUS monitor for some time before it stops working suddenly because of wear and tear or old age of components inside its casing.

If your ASUS monitor is not turning on it could be because of a faulty monitor cable. 

If the device is plugged in and the power light is off, then it could indicate that the power cable has become loose or disconnected. 

If the power light is on but no image appears when you turn on your ASUS monitor, this could be a sign that the video cable has become loose or disconnected. 

If both cables are securely connected but still nothing happens when you press the power button, then this may suggest that either the video card or monitor itself is faulty.

To determine whether the backlight is at fault, you can use a flashlight to shine on the screen and see if it’s still visible. 

If the picture is visible with a flashlight but not without one, then it is likely that there is an issue with your backlight.

7- Old Graphics Card

If your ASUS monitor isn’t turning on, it may be because of an old graphics card that doesn’t work well with newer monitors. 

As technology advances, older components aren’t always compatible with more recent gear. 

That can lead to connection problems and graphical errors, or in the worst-case scenario a non-functional monitor. 

To ensure optimal performance with your ASUS monitor, you should use a more current graphics card that is up to spec with your device. 

If this didn’t work for you, then you need to replace the old card entirely instead. 

Replacing the graphics card may help make sure your ASUS monitor turns on and runs smoothly if that’s not happening already.
