Common laptop screen problems can be annoying and difficult to solve. From dim screens during startup to flickering backlighting, distorted video, black or white screens, blurry text, and sudden shutdowns, there are a variety of issues that can arise. Fortunately, many of these problems can be solved with a few simple steps. The most common cause of a laptop screen being black but still working is a broken motherboard or memory.
To test this, remove all memory modules and replace them one at a time. If one module allows the laptop to work while the other does not, then it is confirmed that one of the memory modules is broken and needs to be replaced. If even replacing the memory module doesn't work, the problem could be due to the motherboard and should be examined by an experienced laptop technician. Vertical lines on the laptop screen can also be solved by unplugging the laptop from any connecting cables, power supply, and removing the battery.
Hold down the power button for about 20 seconds and then restart it. If the problem hasn't been resolved, it may be due to your laptop's signal cable or because the screen itself is faulty and needs to be replaced. The inverter board converts the low voltage used by the laptop into the higher voltage required by the long bulb that illuminates the LCD screen. If your laptop screen breaks, it could be because it fell off, you held it at an awkward angle, or you placed a heavy weight on it.
It could also be due to high electromagnetic interference near wireless signals. If your laptop screen is damaged, you should take it to a reliable service center where they can replace it with original parts. Whether you're using your laptop for work or for gaming, it's important to choose a laptop that meets your specific needs. Press the power button to turn on the laptop and you'll see that the laptop starts up normally or a start menu opens.By following these steps, you can easily solve many of the most common problems with laptop screens.
However, if you're still having trouble with your laptop screen, it's best to take it to an experienced technician who can diagnose and repair any underlying issues.
