The monitor is the eyepiece of each computer. It is where we see what we do and basically our “eyes”. Yet, even monitors cannot escape malfunctions and problems. In these cases, you most likely cannot turn on the monitor (or even if you do, nothing appears). That calls the time for troubleshooting.
Monitor-related dilemmas are oftentimes easy. The usual cases would involve loose and/or improperly plugged cables or the monitor is simply unplugged. However, not all problems are like that. Sometimes, the problem would be directly caused by the age of your monitor (maybe it’s about time you let it retire), or the video card is causing the entire ruckus. Either way, you should get started and troubleshoot it. Here’s how:
- Check all cables - Make sure that all cables are properly placed and plugged in firmly. This may be a bit of a cliché but simple events such as your actions or even your pets’ actions can unplug cables. So, despite this being a cliché, there’s no harm in checking the cables anyway.
- Turn on your monitor – If the monitor shows the message of “This monitor is working properly, please check your cable” accompanied by colored bars on the screen, then it may be caused by your monitor not receiving signals from your CPU. Try using another monitor or another CPU instead.
- If the problem persists even when you try a different monitor or a different CPU, then you may say that your video card is creating problems. Try to check if it is properly placed, and fix it if not. Otherwise you better swap with another graphics card.
Usually monitors work or not work at all. It does not get diagnosable problems as much as the other components of the CPU. If your monitor does not work, try the three steps above. If the problem persists, replace it and NEVER open your monitor. It can kill not your computer, but the computer’s owner.
