  4. At a final resort, try to use your monitor in a different power plug. If it doesn’t work, bring it to the service center.

2] Broken pixels and Stuck pixels

A dead pixel is the second most common LCD screen issue. You will see a black spot on your screen which has no light. It means that the pixel at that point is damaged or not working. Sometimes, it can be a dead pixel or stuck pixel. You can do some troubleshooting steps before taking it to the service center. Dead pixels are often unrecoverable, but give it a try.

4] Buzzing sound and low brightness

Sometimes you may hear a minimal buzzing sound from your monitor. Also, you will experience an uncommon low brightness in your monitor. All these symptoms indicate the issues related to the backlight of your monitor. The backlight issues are mostly found in LCD monitors only because the newer models use LED backlights. You can avoid the buzzing sound by adjusting the brightness accordingly. However, repairing the backlight is the ultimate solution for a very low bright screen.

5] Random Power-offs

It can happen if you are using your PC in a dusty atmosphere. Dust particles cause electricity blockage to various components of your PC and create this kind of issues to your monitor. Dust in the power cable can also cause this issue. Clean the wires and plugs properly to fix this. However, it isn’t always the dust; it can happen due to the faulty or incorrectly plugged power cables. Try replacing cables and changing the plugs. It is not a significant issue.

So these are the most common issues that affect the LCD monitors. Try all the troubleshooting tips mentioned above before taking it to the service center. If nothing works, your ultimate solution is visiting your nearest service station. Good luck.
