Sudden system errors can be called the most frightening phenomenon for PC users. There are still jokes and horror stories about the “blue screen of death”, “the mystery of the black screen”, etc. And, although these phenomena have practically become a thing of the past with the release of Windows 10, one of the phenomena continues to occur for one reason or another. This article will talk about what to do if your screen suddenly turns white.
Why is it better to turn to professionals?
Few people understand that if a white screen appears, then any amateur activity can only lead to further deterioration of the condition of your computer. Therefore, if you are really worried about the functionality of your PC, you should contact a professional service center that is closest to you. There you will be helped by qualified specialists who have the necessary experience in performing such work and who are constantly working, adding to their experience with more and more new practice. Among other things, quite often people who have such a problem come to modern service centers lately, so they can solve it quite simply.
How do professionals work?
Modern specialists can repair your computer in an extremely short time, regardless of how severe the malfunction is. It is worth noting that they carry out a complete diagnosis of your computer, and this procedure is often absolutely free. Since after diagnostics it often turns out that one or another component of your machine needs to be replaced, in this case it can be replaced.
Make sure that you have really high-quality original parts installed. Quite often, modern workshops cooperate directly with the factories of manufacturing companies, so their range is quite large, but it is best to play it safe once again and inquire about exactly what parts will be installed for you. In addition, be sure to pay attention to the fact that the company ultimately provides a guarantee for the work performed.
Viruses or firmware glitches
In such situations, the user can see something like the following picture: the operating system boots normally, after which the computer can even work stably for a certain time without any errors, but then suddenly the display turns white. In the vast majority of cases, this problem appears after the computer tries to connect to the Internet or open any applications.
In this case, you need to enter safe mode, and then completely scan the hard drive using an antivirus program. If viruses are found, you need to get rid of them. However, in any case, the simplest option is to simply roll back the system to a specific checkpoint that you created before or that was created by the operating system you are using.
How to get rid of malware
It is possible to infect a laptop with a virus even with an antivirus program installed, because it is technically impossible to provide absolute protection. If you suspect that problems with your monitor are caused by malware, you should immediately scan your PC for viruses. To do this, you need to launch an already installed scanner or download a new one. The second option is more preferable - if the existing antivirus program allowed a virus into the system, then it is not a fact that it will detect it during a second scan.
To remove malware from your system, you need to do the following:
- Download the antivirus and, if necessary, install it on your PC. A good option is the Dr.Web Curelt program. It does not require installation and is highly effective.
- Log into Windows in Safe Mode. To do this, hold down the F8 button while starting the operating system, and then activate the required item in the window that appears.
- Open your antivirus and select advanced scan.
- Check the boxes for all objects that need to be examined, then activate scanning by clicking “Run scan”.
- After the diagnostics are completed, a list of detected threats will be displayed. All you have to do is click “Disarm” and the antivirus will clean your laptop of malware.
To check the functionality of the monitor, restart the PC and perform the actions that cause the display to turn white. If it functions normally, then you have successfully resolved the problem. If the problem persists, try updating the drivers.
White screen when turning on the laptop. Let's look at the reasons for this problem:
- 1 System conflicts, malware. With this option, the system boots normally and can perform tasks for several minutes. Then the user launches some program or establishes an Internet connection and suddenly a white screen appears on the laptop . Exit: you need to boot from safe mode and scan the entire computer with an anti-virus scanner. If no viruses are detected, but the problem persists, returning the system state to an automatically generated point (via the Recovery Console) may help.
- 2 Damage to the matrix. If the LCD panel fails, the working surface is filled with white immediately or almost immediately when the computer is turned on. However, you can test the condition of the matrix before contacting a specialist. All you need for this is an external monitor from a PC or a TV with HDMI support. If a laptop connected to one of these devices produces a stable image, the matter is clearly a damaged matrix. Possible options: burnout of conductive paths, corrosion, mechanical damage. It is impossible to repair a hopelessly damaged matrix. It can only be changed.
- 3 Failure of the video adapter or north bridge circuit. Both of these components are soldered onto the motherboard and usually fail due to overheating or oxidation of the contacts. A white laptop screen can appear either immediately or a little later - after loading the OS. Repairing both parts is a pointless waste of time. The faulty chip needs to be replaced.
- 4 Problems with the cable. The connecting cable powers the matrix from the motherboard, thus serving as a connecting link between both components. If it is faulty (oxidized, broken), a white screen appears when the laptop is turned on .
The actions of the master are determined after inspection. If the damage to the matrix cable is fatal, it is replaced. If he simply moved away or bent over, losing contact, it is enough to simply correct him. The timing of repair work is an individual issue. If you only need a replacement and nothing else, it will take 60-90 minutes to restore your laptop. If it is necessary to carry out additional procedures (removal of oxides or dust), the duration of the repair will increase.
How to remove white screen during software failures
A sign of a software failure is not the instantaneous appearance of a white screen immediately after startup, but after some time.
For example, after connecting to the Internet or launching a program. Software failures generally occupy a small part, but fixing them yourself is easier than hardware failures.
What to do if there is a software error? Since when a white screen appears, system repair is not available to you, boot into safe mode.
Then scan your hard drive with your antivirus, or even better, with the free Doctor Web utility.
A system restore (rollback) using one of the saved points also gives a good result.
Recovery is a good tool, but if the system was damaged by a particularly sophisticated virus, then the rollback may be blocked, and this also happens.
Then, in addition to Doctor Web, scan your computer/laptop with the AVZ utility - it is also completely free and in Russian.
Checking the screen matrix
You can also test the screen matrix yourself. For this purpose, the partial deformation technique is used. First, try to press a little on the matrix in the places where the stripes are most concentrated, and then try to bend it a little in the horizontal plane.
If the colors change during deformation, the matrix will have to be replaced. The same should be done if there are noticeable ripples or a wide white stripe across the entire screen, or the image looks like a negative, or there is color substitution throughout the system boot stage (even when entering the BIOS settings).
Matrix malfunction - what to do
If immediately after Windows 7 or any other starts loading, a white screen appears and the computer freezes, there is a possibility of a matrix malfunction.
How can you be sure? Connect the laptop to an external monitor (or to a TV). If there is no interference and no white screen (you will see a clear image), then the matrix is covered (there is no 100% guarantee).
It may simply burn out or be damaged mechanically due to contacts, moisture, or the laptop simply fell.
This malfunction can be recognized immediately. The computer turns on, and instead of loading normally, you immediately see a white screen.
What to do if the matrix burns out? It cannot be restored; it will have to be replaced.
Problems in the matrix
Unlike any viruses or software malfunctions, a matrix problem almost immediately appears as a white screen. In other words, the problem occurs immediately after the user turns on their computer.
However, it’s worth noting right away that you can’t say that the display is broken based solely on the fact that when you turn it on, there’s a white screen. You can try to confirm your fears (or, conversely, refute them) after your computer is connected using a specialized HDMI port to the TV. If another desktop monitor is available to you, then you can use that as well.
If the new device has the correct image and everything works relatively normally, then in this case you will have to change the monitor or display depending on where exactly the white screen appears. Only professional diagnostics will tell you in more detail what to do, but in such a situation, of course, you will have to give the device for repair to professionals from the company in which the verification procedure will be carried out.
Malfunctioning motherboard chips
Malfunctioning motherboard chips
If a white screen appears after launching games or videos, then the reason may be the video card or the north bridge.
What are the signs? A white screen appears when Windows starts or after a few minutes.
What to do in this case? If you are sure that the video card is the culprit in the appearance of a white screen, you will have to change them.
There may be many more reasons than are described here, purely individual ones, so to speak.
What to do then? Ask for help. Where? Describe the signs of a monitor color change in the comments. Good luck.
Damage to the train
The matrix cable is a kind of intermediary between the display of your computer and the various power elements of the motherboard. It is worth noting that this part is quite thin, as a result of which, if a strong mechanical impact is exerted on it or some unqualified specialist interferes with the insides of the computer, you should not be very surprised that the cable will ultimately be torn.
It often happens that the problem is only in the bend of this cable, that is, in principle, it is in working condition, but has lost contact. The consequence of this problem is precisely this situation when a white screen appears when the computer starts.
Fixing the problem: white screen when turning on the laptop
Software glitches or technical breakdowns cause a white screen to appear immediately after turning on the laptop or fully loading the operating system. If the OS boots normally, then the problem lies in the presence of viruses or incorrect operation of the video card driver. If a white screen instantly appears without boot lines appearing and you cannot enter safe mode, you need to pay attention to checking the components. This problem can be solved in several ways.
Please note that the first two methods are only suitable if it is possible to start the operating system. You must boot from safe mode if the appearance of a white screen prevents you from completely cleaning your computer from viruses or reinstalling drivers. In all versions of OS Windows, the process of entering safe mode is almost identical, and detailed instructions can be found in the articles linked below.
When standard methods fail to start the operating system in safe mode, you can try to do it using a boot disk. Read more about performing this process in our article at the link below.
Method 1: Cleaning your computer from viruses
The entry of virus files onto a computer provokes certain malfunctions in the operation of the entire system. First of all, if the operating system loaded successfully, and after that a white screen appeared, you need to perform a full scan of the computer with an antivirus program. You can choose the most suitable software for yourself using the link below. In addition, our website contains detailed instructions on how to combat computer viruses.
Method 2: Restoring drivers
Sometimes drivers, if installed or updated incorrectly, stop functioning correctly, resulting in various errors appearing. The occurrence of a white screen is associated with incorrect operation of the video card or display driver, so you will need to restore them. This can be done using special programs that will automatically find, download and install the necessary files. You will find all instructions for using such software in our articles at the links below.
The Windows operating system contains standard tools that allow you to automatically search for drivers on the network and install them. Attention should be paid to the video card and display. Go to Device Manager and check the required components one by one for updates or other relevant files. Read more about this in our other article at the link below.
Method 3: Connecting your laptop to an external display
The easiest way to determine a hardware failure of a laptop’s matrix or video card is by connecting it to any external display – a TV or monitor. Most modern devices have an HDMI connector, and the connection to the screen is made through it. Sometimes other interfaces may be present - DVI, VGA or Display Port. Select the most suitable one and check.
Sometimes, after rebooting the device, the external display is not detected automatically, so you need to manually activate it. This is done by holding down a certain key combination, most often Fn + F4 or Fn + F7. In the case when the image on the external display is displayed correctly, artifacts and a white screen do not appear, this means that you need to use the services of a service center to diagnose and correct breakdowns.
Laptop
Most often, they are not software failures or errors in drivers or their conflicts with the operating system, but hardware failures, which include:
- regular and/or significant overheating of the graphics chip;
- malfunction or disconnection of the cable between the graphics adapter and the display (usually in such cases a corresponding notification appears on the screen, such as “No signal”) because manufacturers do not secure them in any way in the mounting locations;
- malfunction of the display matrix (failure of it or the controller that controls it).
Software causes are extremely rare. And this applies to both flaws in the video card driver code and any incompatibilities or conflicts with other system components.
Solution
Let's go in order and start with overheating of the graphics adapter core.
You can check whether the temperature of the chip has exceeded the limit for normal operation (sometimes not long-term) for which it is designed, in many ways, or rather, with applications.
Software
We are using the AIDA64 utility, which is familiar to many users under the name Everest, although first you should make sure that the fan cooling the graphics adapter core is spinning and does not make unnecessary noise.
- Launch the installed application or its portable (portable) version.
- In the main menu or in the tree in the left column of the main window, click on the “Test” button, where we select the “System stability test” option.
- Further about.
Rice. 2 – Running a system stability test
- At the very bottom of the window, click “Start” to start the computational process.
If you see that the temperature is approaching the maximum permissible for the functioning of your computing device, stop testing.
To identify dead (faulty) pixels, if an area of the screen has turned white or white dots have appeared on it, you need to run the monitor diagnostic tool from the “Service” main menu item.
Rice. 3 – Running the laptop display diagnostic utility
In the program window that opens, we don’t touch anything, just click on “Auto Run Selected Tests”.
Rice. 4 – Selecting algorithms for searching for dead pixels on the screen
Several other tiny but popular utilities can do essentially the same thing, but faster.
- Download GPU-Z and the official website.
- We launch it and go to the second tab, where the third line “Temperature” will show its current indicator.
Rice. 5 – Information from GPU-Z sensors
In the laptop manual or on the website of the graphics adapter manufacturer, we look for information about the frequency range available for the normal functioning of the graphics core of your laptop computer.
If your value is outside the acceptable limits, check the graphics adapter cooling system.
Most likely, the fan blades and radiator fins are clogged with dust, which prevents them from fully performing their intended functions.
Another application that allows you to monitor the temperature of your video card is HW Monitor.
The entire time it is running, the utility will monitor the temperature sensor installed on the graphics core.
Separate columns display the minimum and maximum recorded temperature, as well as its current value, measured several times per second.
Rice. 6 – Graphics adapter temperature
If the problem appears after starting the operating system or a specific application, such as a game or media player, you most likely need to reinstall or update the drivers for your video card.
The best way to do this is to use the official website of the laptop manufacturer or graphics chip developer :
- for Nv video cards >It is not recommended to use various kinds of packages for automatic driver installation in such situations.
It is also possible to use the operating system's Device Manager.
- We open it as follows: hold down the Win + R keys, enter “devmgmt.msc” and execute the command.
The search bar is useful for this.
Rice. 7 – Launch Device Manager
- In the window that opens, call up the context menu of your adapter and select “Update”.
Rice. 8 – Selecting a video card in Device Manager
- We select the option to automatically search for the latest driver versions to control the operation of the video card and wait for the process to complete.
If one is found, the system will automatically download and install it, which will take time.
Then you should restart your computer.
If none of the solutions helped, or the problem does not allow you to complete the steps in the instructions (a white screen appears after starting the operating system), try booting into safe mode.
Hardware
If artifacts are noticeable immediately after starting the computer, there is a high probability that its cause lies in the disconnection or damage of the connecting cable, usually located between the cover and the keyboard unit.
In this case, you can try slowly closing and opening the lid while watching the picture.
If artifacts appear in a certain position, then it is necessary to replace the cable or check the reliability of its connection.
In cases where it is partially disconnected (this happens extremely rarely), you can fix everything yourself, but to do this you will have to disassemble the laptop.
In other situations, the computer must be taken to a service center for diagnostics and, possibly, to replace the matrix, which costs a lot.
Smartphone
The white screen on your phone or tablet appears much more often.
Let's consider a list of factors that lead to such breakdowns and possible options for eliminating them.
Here are the most common reasons why you may see a white screen on your mobile phone or tablet:
- The device has been submerged in water or has become wet in the rain . This reason is difficult to identify, because after getting wet, the contacts and joints begin to rapidly oxidize, and a failure may appear after a few weeks.
- Confirmation of strong vibration or fall - physical damage to the matrix elements.
- Working or staying for a long time in conditions close to extreme , for example, high dust or carrying in a very unclean pocket. Dust microparticles often penetrate deep into the housing and often lead to short circuits, especially if the particles are metal.
- In some cases, the software may cause the operating system to malfunction or, after launch, display a static image, including a white or grayish color. Most often this applies to applications downloaded from third-party resources.
White screen problem
A white screen appears on your phone display for two main reasons: hardware or software failure. In the first case, the hardware itself (display, cable, battery) fails. In the second, the breakdown occurs directly due to problems in the Android operating system. To determine repair tactics, you will need to establish the true reason for the appearance of a white screen on your mobile phone.
You can understand the reason yourself. If the smartphone was dropped from a long distance, damaged during an extreme trip, or overheated in the sun, then the white screen was formed due to hardware problems. If failures occur after installing an application, then the cause is a software failure. The main factors influencing the breakdown of the gadget include:
- regular mechanical damage, in this case, in addition to the bright screen, spots, stripes, and black dots may form on the display;
- mobile phone contacts with water. Stripes, colored spots, and ripples may also appear on the display;
- contamination of the gadget (ingress of dust, dirt particles);
- prolonged exposure of the smartphone to the sun;
- installation of programs from unknown sources.
Often a white screen on Android appears after a system flashing.
Restoring driver functionality
The laptop screen may also turn white if the drivers for the display or video card are damaged. In this case you will need:
- Start the laptop computer and insert the driver disk that came with the laptop into the drive. If there is no such disk, you can search for the required drivers on the website of your laptop manufacturer.
- Enter “Device Manager” and select the “Video adapters” section.
- Open the video card available there and in the “Driver” tab click “Update”.
- In the window that appears, select “Automatic search...”.
Follow exactly the same steps in the “Monitors” section.
What to do in case of breakdown?
According to statistics, the most common reason for the absence of an image on the phone display and the appearance of a light screensaver is mechanical damage. Frequent impacts and falls from great heights damage the smartphone matrix, which leads to its breakdown. A person who does not have the proper qualifications is unlikely to be able to fix problems on his own. In this case, there is a risk of permanent breakdown of the gadget. Experts recommend contacting a service center for professional repairs.
The appearance of a white screen does not always mean that the user will have to buy a new mobile phone. Sometimes the damage can be easily repaired at home and without the help of specialized equipment. In addition, there are many topics on technical forums where experienced users share nuances related to mobile phone repair.
Hardware and mechanical damage
If damage is detected, the user needs to clarify information about whether the gadget is under warranty or not. If the phone's warranty has not expired, you can simply take the smartphone to a service center. Otherwise, you need to contact a regular workshop or try to restore the system yourself. The following problems can be solved at home:
- loop restoration. If, when disassembling the smartphone, it was discovered that the cable has moved to the side or has completely come off, you will need to release the wire, treat its edge with an alcohol solution, dry it and insert it into place;
- matrix restoration. The repair scheme in this case looks similar. The user only needs to first purchase a new matrix for a specific Android model.
If a white splash screen appears on the display after trying to reflash the phone, this indicates that the installation of the program was unsuccessful. The user will need to download the official firmware version from reliable sources and repeat the procedure again.
The cable is disconnected or damaged
To restore the loop, you must:
- Remove the back panel of the gadget, remove the battery from it (if possible);
- Remove the fastening screws;
- Remove the board that is located under the screen;
- Remove the insulation with a needle; at this stage you can use a magnifying glass;
- Arm yourself with a soldering iron, wrap a copper wire tip around it;
- Solder the cleaned surface of the conductor;
- Pull up the edge of the torn cable and solder it to the motherboard;
- Wrap thermal film around those places of the cable where the soldering occurred;
- Heat the film until it begins to stick to the tape (this can be done with an iron).
Now you need to wait until the structure cools down and assemble the mobile phone. If the screen remains white when turned on, it is better to take the gadget for repair for a more thorough diagnosis of the problem and subsequent repair.
Moisture has entered the phone case
If your smartphone falls into water, do not hesitate and wait for a visit to the specialist. The user will need to immediately remove the battery and SIM card. If possible, it is better to completely disassemble the device. All parts must be laid out on a dry towel, left for several hours until completely dry, then treated with an alcohol solution and dried again. After this, you should assemble the smartphone and check it for serviceability. If the screen remains white, only a specialist can help.
The chips and board are faulty
With regular mechanical damage, microcracks form on the board, which leads to solder joints bursting or module legs torn off. It is unlikely that you will be able to diagnose this breakdown yourself, since a person will not be able to visually assess the condition of all the small parts. The user will have to seek the help of a repair service. An experienced technician will quickly determine the cause of the breakdown and help clarify the situation. If the chip turns out to be repairable, he will fix it. Otherwise, the user will have to purchase a new motherboard or smartphone (depending on the cost of the part for a specific phone model).
Desktop background disappears in Windows.
The problem is not uncommon and happens on different computers and at different times. It's actually very easy to fix.
If you yourself set a background image for your desktop, then most likely the place from where you set it was remembered by the system; the system, of course, makes a copy of this image, but first turns to the original source. I recommend putting your image in the “Images” folder and setting it as your desktop background image.
The file should be left there, not deleted.
This fixes the problem almost always.
If the problem persists, then there is such a function in Windows 10 “ Optimizing the screen image
” at the very bottom there is an item and there should not be a checkmark “
Remove background images (if possible)
”.
If it is there, then you should repeat Step 1
.
If it is not there, then move on to the next option.
Create a new account and transfer everything you need there. Instead of digging now and going through all the possible situations that led to this misunderstanding, we do it simply and create another Windows account.
You can do it in different ways. Clauses 3.1 and 3.2. (the result is the same).
To do this, write in the search engine “ Family
” in the search engine it comes up “
Adding, changing and deleting other users
“, this is what we need.
There in the paragraph “ Other users”
“Click “
Add a user for this computer
.”
A dialog box will open in which we select “ I don’t have this person’s login information
.”
Next ” Add a user without a Microsoft account
” and enter the username. After switching to a second account and after transferring all the necessary data, the old user can be deleted for convenience.
You can do the same using “ Run
” (WIN+R) drive in “
netplwiz
“.
There we click on “ Add
” and select “
Sign in without a Microsoft account
“.
In the next paragraph, select either “ Microsoft account
”(you will have to register on the site).
Or a “ local account”
. And just like last time, we enter the username, similarly to the last time, we transfer everything necessary and delete it for convenience.

The appearance of light spots and stripes on the screen
During operation, users may experience spots or streaks appearing on the phone screen. There are several options for the origin of such breakdowns:
- sensor detachment. During use, the mobile phone sensor may peel off at the edges, which leads to the appearance of light stripes in places of peeling;
- failures in the operation of a single modular part;
- Matrix malfunctions.
The cause of dead pixels may be a manufacturing defect. This is expressed in the formation of miniature multi-colored dots on the surface of the matrix. You can see them if you put a plain dark-colored screensaver on the background. Depending on the model of the gadget, the presence of such defects is considered acceptable for regular use.
The following reasons can contribute to the formation of light spots and streaks on a smartphone:
- moisture entering the phone device;
- sticking of light-scattering films;
- mechanical damage;
- local overheating of the device.
Dark yellow spots on the display may be due to an incorrectly installed heat sink by the smartphone manufacturer. If subtle stripes and spots appear on the screen that are only visible from a certain angle, this may indicate a software glitch. In this case, the user can try to take a screenshot of the main screen. To create it, use navigation buttons (simultaneously holding down the lock and volume down keys) or accessibility functions (swipe your fingers across the screen). If there are no stripes in the resulting image, the problem may lie in a dysfunction of the display controller.
If streaks appear on the image, the problem is systemic. The user can try to reset the settings to factory settings (all existing files can be saved in a virtual cloud). If you cannot eliminate the stripes and dots, it is better to seek help from a specialist.
Vertical stripes on the display appear due to damage to the matrix. In this case, only replacing the touchscreen will help get rid of the breakdown. Streaks and light spots sometimes form due to continuous operation of the device and long-term operation of the backlight. This leads to video chip dysfunction and system failure. A technician at a service center can save your mobile phone.

Let's summarize: how to solve the problem
What to do if a breakdown is detected:
- Find out about the warranty period for your phone. If the coupon is still valid, it is better not to try to repair the gadget yourself, but to take it for free diagnostics;
- If the warranty card has expired, try to disassemble the mobile phone yourself: examine the matrix, examine the condition of the cable. If stripes appear on the screen, you should try to reset the settings to factory settings.
- If you were unable to solve the problem yourself, you should urgently contact a service center.
A breakdown does not always lead to the purchase of a new gadget. If the user contacts the workshop in a timely manner, he can count on the complete restoration of his mobile phone.
