If you turn on your computer but it shows an empty screen with no power or display, there’s definitely something wrong going on. You don’t have to fret though. This problem can be solved easily depending on what has caused it. There are several reasons why a PC monitor suddenly refuses to turn on.
The first thing to do in this situation is to check the cables. Most problems with computer screens are related to loose cables. Check if the VGA cables are connected securely to your PC monitor. If there are loose screws, the cables may not be held in place correctly which leads to monitor problems. Tightening up the screws may help in solving the problem. Additionally, check if the UPS has short circuited. Plug the monitor to a wall socket and determine if you need to replace the surge protector.
Sometimes, the problem might be the monitor itself. If you have a spare monitor or other computers at home, you can try using a functioning monitor to replace your monitor and see if it works. On the other hand, if it doesn’t work, you may have to replace the monitor since the problem could be the computer screen. If it does work, the problem may be related to the video card. Monitor failure can be caused by a loose video card. You can check if the video card is seated properly by opening up the case. Make sure that your computer is turned off and unplugged from the power source. Try pulling out the video card and inserting it back securely. Check if this solves your problem. If the loose card has caused the problem, your monitor should be able to power on and function normally again. If the video card doesn’t work properly anymore, you may have to replace it. Ask help from an expert friend.
Whatever happens, never open the monitor and tinker with it to avoid risks. It can be quite dangerous since it is made up of intricate parts that even some expert technicians do not want to disassemble. If worse comes to worst, you should just opt to change your monitor instead of trying to fix it inside. If your PC is still under warranty, you can also send it back to the manufacturer so that computer technicians can check and fix it. However, it can be a very long and tedious process. Another alternative is to hire a professional computer specialist to check your computer and repair the problem.
