Fixing the hardware problems

If you are seeing distorted lines or colors on your laptop screen, you can take it to a good laptop repair and maintenance shop nearby. If you have a warranty, it’s best to take it to the manufacturer’s authorized repair centers. It will save you money.

So, the most common thing to do is to take your laptop to an expert. But if you decide that you will fix the problem yourself, do as we tell you. Following are the steps you can follow to fix your laptop screen yourself. Please read them carefully.

Restart your laptop computer

If you see distorted lines on your screen or weird colors on your screen, the first thing you should do is restart your laptop. Simply shut your computer down properly and wait for 5 minutes. 

Sometimes unfinished processes, RAM overload, malware, viruses, and similar things might cause your laptop screen to show weird colors and lines. If your problem is this, a good old restart will fix it! If it doesn’t, there are other ways that you can try.

Use an external monitor and fix the problem

If a restart hasn’t fixed your screen problem, you need to figure out whether or not your laptop screen is having problems. So, you can use a monitor to test your laptop screen. However, you may not have an external monitor at home. So what do you do?

You certainly shouldn’t buy a new laptop monitor just to check your laptop screen. Take the help of a repairman on testing your laptop. You can take your laptop to a repair store. They will check it out for you. You shouldn’t be charged for that. 

If you have a friend or someone else who has an external monitor, you can ask them to let you check your computer. It just takes a few seconds. Then, you can work on fixing the issue.n

If you have access to an external monitor, you can test your laptop easily. Here’s how you can do it.

You need to have a VGA cable/DVI cable/ S-Video cable or HDMI cable to test. Simply put, you need to have any of these cables to be able to test your computer on that monitor. Keep in mind; all monitors don’t support HDMI cables. Be sure about that before buying one. Almost all laptops allow VGA connections. It’s safe to use a VGA cable for that purpose. Don’t forget to check out the external monitor as well. Make sure it’s good.

Connections are automatically detected on modern-day laptops. So, you will start seeing results on both the monitor and laptop screen. If your monitor can’t do that, you need to establish a connection manually.

You need to use the function buttons of your keyboard to switch the display between internal and external modes. The buttons are different for different brands.

• For HP laptops, press the Fn+F4 key

• For Toshiba, press the Fn+F5 key

• For Dell, press the Fn+F8 key

• For Lenovo, press the Fn+F7 key

You will access the connection menu this way. Now, manually connect your laptop screen with the monitor. 

You will see results on both screens now. If the display is weird on both screens, it’s probably because of outdated graphics drivers, a poor LCD connection, or a bad cable.

If you see good results on the extra monitor, but the laptop screen displays weird lines, you need to fix your laptop’s screen. You can take it to a repair shop. If the problem is minor, you can do it yourself.

This is a pretty simple thing to do. If you know the model of your graphics card (Nvidia, AMD, Intel), look for the latest driver for it. Update the video card drivers of your laptop to the latest available version.

If you don’t know your graphics card model or want a simpler experience, you can use an app. We recommend an app called DriverFix. It’s really cheap. You can get a license for a single PC for around $20 per year. The app will automatically detect faulty or outdated drivers. You can update them easily.

If this doesn’t work for you, consider replacing the graphics card.

Check the LCD cable connection with the motherboard

If your laptop screen doesn’t have any issues, but you still see vertical lines on your screen, it’s maybe because of a poor connection between the laptop’s LCD and the motherboard. Let us explain how it works.

The motherboard of your laptop sends signals through a cable. The connection needs to be good to get the expected results. A poor connection or a bad quality cable prevents that from happening. 

If the cable has breakage or is worn out, it’s risky for you to keep using it. You will see distorted vertical lines because of this. You should change it.

Check if the cable is plugged in properly. If it’s loose, plug it in properly. The connection between the laptop’s LCD panel and the motherboard is placed under the keyboard. You need to dislodge the keyboard first. Check videos and guides on how to do it.

Replace the LCD cable

A poor LCD cable will disrupt your viewing experience. If the cable is worn out, you should definitely get a new one. It doesn’t cost much. You can try wiggling the cable if it looks in good condition. You need to change the cable as well if you see the computer screen flickering or showing distortion while wiggling.

Check the display screen

If you didn’t have any issues with any previous methods, you should check the screen itself. Before changing the PC screen, you need to be sure that it needs replacement.

Press gently on the upper portion of your laptop’s display. If you see distortions or colorful spots, it’s time for you to get a new display. You can take our word for it. If you don’t get it replaced soon, it’s only going to get worse.
