Are you in the middle of an important task and suddenly your computer’s monitor refuses to turn on? It’s an all-too-familiar and frustrating experience.
Whether you’re trying to work, watch movies, or play games, not having a functioning monitor can be extremely inconvenient.
If your computer screen isn’t switchin’ on, it’s likely due to a power issue. Ensure that the cable is firmly inserted into the back of the display and that the outlet is functioning. Assuming the cord and socket are fine, check the power button to make sure it’s positioned correctly. Power might not be reaching the monitor due to a faulty circuit breaker or fuse box. A new monitor may be needed if all of these options fail.
Here we’ll take a look at the most likely causes of this monitor issue in depth, and some potential solutions.
Read on to learn more about why your monitor might not be turning on.
11 Reasons Why Monitor Is Not Turning On & Their Solutions!
One of the most common issues encountered with computer monitors is when they don’t turn on. In this section, we will discuss the reasons why a monitor may not turn on and the possible solutions.
1. Faulty Power Supply
One of the most common reasons why a monitor won’t turn on is because of a faulty power supply. The power supply provides power to the monitor and if it is not providing enough power or if it is not working properly, then the monitor won’t turn on.
To fix this issue, you can try replacing the power supply or using a different power source to see if that fixes the problem. Also if the monitor is plugged into a surge protector, ensure that the surge protector is switched on.
2. Check Connections
If the power supply is working properly, then you should check the connections between the monitor and the computer.
Make sure that the cable is connected properly and that it is not loose or damaged. If the connections are loose or damaged, then you may need to replace the cable.
3. Inspect the Video Cable
In case your monitor won’t turn on, it could stem from a problem with the video cable.
Inspect it closely and make sure it’s connected firmly from the PC to the monitor. If the cord is loose or damaged, this could be the source of your monitor’s woes. So, check that video cable: VGA, DVI, HDMI, or DisplayPort.
4. Test With a Different Computer
If the issue persists, it may be an issue with the computer itself. Try disconnecting the video cable from the computer and connecting it to a different computer to see if the monitor turns on. If it does, then the issue is likely with the original computer.
5. Check the Monitor Settings
When past attempts have failed to produce the desired results, the monitor’s settings could be at fault. Verify that a power saving mode isn’t enabled, as this could be the reason for the monitor’s lack of activity. Additionally, ensure that the brightness and contrast are adjusted accordingly.
6. Reset the Monitor
If all of the above solutions have been attempted and the monitor still does not turn on, the last resort may be to reset the monitor.
This can be done by disconnecting the power cable and pressing the power button for several seconds. After a few minutes, reconnect the power cable and attempt to turn on the monitor.
7. Driver Issues
An issue with the drivers could be causing the monitor to not light up. If the drivers for the monitor aren’t running optimally, or need a refresh, the monitor won’t power on.
To rectify this, try updating the drivers or reinstalling them entirely.
It could be the overheating of your monitor that’s causing it not to fire up. The fan might not be functioning as intended, or the vents may be obstructed.
To remedy the situation, give the vents a good clean, and make sure the fan is running smoothly. If it’s worn out, you’ll need to get it replaced.
9. Faulty Motherboard
Another reason could be due to a defective computer’s motherboard. Be sure to take a closer look at the motherboard for any signs of corrosion or damage. If the motherboard is irreparable, you may need to replace it.
10. Failure of the Graphics Card
In case the motherboard appears to be running correctly, the culprit may be the graphics card. If so, you may need to switch it out for a new one.
11. Monitor’s Backlight problems
When your monitor displays nothing but a dark, black void, try casting light directly onto it with a flashlight. If you can make out an image with the flashlight, then the likely culprit is a faulty backlight, which will require professional replacement.
Note that due to the potential for damaging the monitor, it’s best to leave this repair to a qualified and experienced computer technician.
If none of the solutions suggested above have worked to resolve your monitor not turning on the issue, it may be time to contact your manufacturer for further help. Many monitors come with a warranty that covers repairs if something were to happen to the monitor.
It is always a good idea to check your warranty to see if you’re covered. It may also be time to invest in a new monitor if the issue cannot be resolved.
