One of the most important components of a portable computer, the screen is not free of flaws that can greatly disrupt the user’s experience with the device. But, after all, do you know the main problems on the notebook screen? More than that: do you know how to solve them? The purpose of this text is to help you with these questions, in a practical way.


Let’s start listing the main notebook screen problems, and how you’ll be able to solve each issue. There are some situations that are simpler and others that are more complex. Therefore, the user should try to follow the recommendations in the most detailed way possible. In case of difficulty, it is best to consult specialists to help you.


This is usually one of the most common problems, and is usually caused by falls or more sudden contacts. A scratched or broken screen certainly harms the user’s navigation on a notebook, as the visual aspect can be quite compromised. As it is a sensitive component, the big tip for the user is to transport the device with due care, as we will see later on. However, if the screen is scratched or broken, the most appropriate resolution in this case is to replace the component.


Is your laptop screen flickering non-stop or even occasionally? This is another serious problem that can have several causes. It could be a defect or just a bad contact in the flat cable, which is the cable that connects the screen to the board. If this is the identified problem, you will need to replace the ribbon cable. However, if this measure does not solve the problem, be aware that this failure may involve other components of the device, such as the processor and the memory part, driver and even be caused by loose or poorly fitted items and, in extreme cases, by dirt. on equipment parts.


There are several reasons that can make your laptop screen dark suddenly. Therefore, it is important that the user is able to correctly identify what is causing the problem. Below, we will list the main ones that can make your notebook screen dark.

They range from the simplest to the most complex cases. In the simplest block, we can consider the very low screen brightness and the notebook on the rest screen. A small inattention can confuse the user so that he thinks that his screen is damaged. Other more common problems involve viruses in the machine, misconfigured notebook, problems with the flat-cable and short on the motherboard, among others.


In many moments, the green screen is just a runtime error in our operating system in its routine processes. When this happens, just restart the machine to see if this problem is indeed the cause of the green spot on the screen. The tip is always to adopt this procedure as an initial measure for any abnormal situation that may appear on your device. Sometimes a reset will automatically fix these less complex issues.

Another possible cause for the stain on the notebook screen is the outdated driver of your device. He is responsible for making the communication between the hardware and its operating system, thus being fundamental for the screen to work correctly.

The vast majority of operating systems already come with drivers in their latest update and also have automatic routines to identify possible configuration delays. Even so, to make sure your driver is up to date, you can check directly with your device’s manufacturer, who usually provide these software to the user free of charge.


As well as a series of other situations that can occur in other notebook components, the main causes of the all white notebook screen can derive from both the hardware and the software. However, for this case, the vast majority of cases will be involved with problems in the former. Among them, we can mention:

Problem related to the flat cable of the screen : this is one of the main causes of the white screen of the notebook. It can happen when the cable that transmits the signal from the motherboard to the monitor is simply disconnected.

VGA chip error : in some devices that have a removable video card, there may be a failure in the VGA chip, the component responsible for managing the device’s power supply and shutdown;

Defective motherboard : when there is a problem with your notebook’s motherboard, there is a loss of voltage between the board that powers the screen, causing visual defects. Among these failures, the appearance of the white screen may occur.


A notebook screen showing horizontal lines in its structure can have several explanations and causes. Outdated drivers, incorrect connections of the device’s video cables, and even problems with the flat cable.

The most effective way to try to diagnose the real reason for the appearance of the lines is by entering the settings of the BIOS (Basic Input and Output System), which has the power to define whether the problem is related to the hardware (physical part, such as USB cables , for example) or the software (programs and operating system) of the device. If it is hardware related, you may need to replace the ribbon cable. The good news is that this item is easy to replace and is relatively inexpensive compared to other notebook components. And of course, definitely much more affordable than replacing the screen with another one.


Another important issue to pay attention to and that directly dialogues with our first topic is the incorrect handling of the notebook which, in turn, can damage the screen, from shocks and stronger contacts. The tip here is to transport the device in a protective compartment, such as a bag or cover made especially for this. These elements help to minimize possible damage in the event of a notebook crash. Another basic recommendation is not to transport the device with the screen raised. Any possible damage will be greater if the device is in this way.
