Why is the monitor pink? Four reasons why our computer screen color turned green
Unfortunately, sooner or later all equipment and electronics fail. This happens to everyone, so don’t worry about the fact that one day you open your laptop and find problems with the laptop - (for example, red screen). Namely, about this unpleasant situation when the screen is filled with red, we will talk today. This situation is quite common, it happens with different models laptops, well known to repair specialists and all service center employees. They call it the “red screen of death” and it is known as the computer boot signal. emergency mode.
When turning on the laptop there is a red screen - what are the causes of the malfunction?
There may be several reasons for the appearance of a red (or pink) screen - some are buried in software and talk about incorrect operation“brains” of the laptop, while others indicate mechanical problems and require hardware repair. To figure out which reason led to the appearance of the red screen in your case, you need to monitor the progress of the laptop booting and operation.
When A red screen appears when I turn on the laptop, but it loads and continues to work without distortion on the screen, this indicates critical errors that have occurred in the system. This happens with Windows Vista (Windows Longhorn) - the error signal in the beta version of this OS was displayed on a red background. In common Windows versions 98 also loaded with a red screen and indicated that there were critical errors.
Red screen and hardware problems
If, in case of problems with the operating system, a red screen indicates an emergency mode, but the computer boots and works, then if there are problems with the matrix or video card, after the system boots, red stripes remain on the screen, and the image or video itself is often blurry. This happens when the monitor cable frays or comes off, the video card burns, or malfunctions appear in the matrix itself. Often the video adapter and VGA cable also suffer. In any of the above cases, you must contact the service center for repairs.
You can do the simplest fault diagnosis yourself - open and close the laptop lid a couple of times, while observing the changes on the screen. Do you see the screen color changing when buried and opened? Most likely injured VGA cable. But if you found red screen when turning on laptop, which itself begins to change color, then we can assume that it is the video chip that is faulty.
The laptop boots as usual, but the colors are greatly distorted - everything loads in red, and a strange flickering of the screen appears. Is there any smudges, streaks or ripples on the screen? Try connecting external monitor. If the image on it is correct, it means that the screen backlight has probably failed. The problem can also be solved by contacting a service center.
Features of laptop repair service center
When looking for a repair specialist, remember that if you have a warranty card and terms warranty repair you can get your laptop repaired for free. But this can only be done if the laptop does not have mechanical damage, all factory seals are intact, there are no traces of external interference.
As a rule, problems associated with the screen turning red are resolved at the service center quite quickly. If the matrix cable comes loose, the repair shop will simply put it in place and secure it. This repair will not require much time.
The same can be said about problems with the OS. If necessary, specialists will reinstall you operating system or fix the errors that have arisen - the red screen will no longer appear when booting the laptop, as the system will resume correct operation. All your data and files will be saved on your computer safe and sound.
If you need to make a larger repair - repair the backlight, change the matrix or video card, it will take more time. Be prepared to wait for spare parts to arrive from your laptop manufacturer.
Good afternoon, dear blog readers! We remember the good old days when the TV screen was on cathode ray tube suddenly changed color? The hand itself reached for the slipper, just like when hunting a cockroach. But the same fate can befall even modern monitor. I was once asked to figure out why the computer screen turned green. A very simple and quick diagnosis followed.
For quick diagnostics I needed:
- extra VGA wire
- laptop
First it was necessary to disassemble the existing circuit - monitor + VGA cable + old desktop computer. Upon disassembly, it was discovered that the VGA cable was not a simple one, bought for three pennies in the transition, but with gold-plated contacts! Then the laptop was connected to the monitor, first through a VGA cable with gold-plated contacts, then through the cable that I brought. Which was without frills. The result was not long in coming, but... first things first. What potential causes Could there be an unexpected change in the color of the monitor screen? Why is the screen color now green?
- problem with computer video card
- problem with the monitor
- there is a problem with the cable, for example, there is a break or rupture in its wires
- Problem in software settings colors
Let us briefly examine these hypotheses in order.
Video card problem
A malfunction in the graphics chip, for example, its partial failure, is the main reason that the video card “paints” the monitor screen a certain color at the output. Blade GPU we can cure it at home by warming it up with a special hairdryer. But, to be honest, I haven’t practiced this yet.
If you have a discrete video card in your computer, then it must be inspected for swollen capacitors or other burnt parts. Swollen condensers can be replaced yourself if desired.
Overheating of the video card can lead to the result described. First, it is worth checking the temperature of the video card with the well-known GPU-Z program, so as not to waste something that is securely fastened with tape and works that way. We should not see numbers greater than 90 degrees in the GPU Temperature field. Once I saw the processor temperature about 100 degrees, and it continued to rise rapidly. I had to severely disconnect the computer from the network, otherwise it was in danger of self-digestion.
If it turns out that the temperature of the video card is really going through the roof, then it’s time to clean the inside of the computer using a vacuum cleaner or compressor, then, if necessary, check the functionality of the cooler on the video card and replace the thermal paste underneath it.
You can also damage the connector on the video card, especially if you pull the cable too hard. This can be checked by slightly shaking the connector itself. If it does not stay in place like a glove, then this may well be the reason for the monitor screen to turn a certain color.
The video card connector on the motherboard could become unsoldered during its life. If, when the video card is slightly shaken in the motherboard connector, something happens on the monitor - the screen tint changes, artifacts appear or disappear - then all this clearly indicates a problem with the connector on the motherboard. It is treated by re-soldering it. Or sending the motherboard to a service center.
Finally, the video card drivers could fail. This should be checked last if we suspect a hardware problem, but we must keep this option in mind. Download from the video card manufacturer's website fresh drivers and install them. I hope it doesn't fall out for you!
Problems with the monitor itself
The screen color may have turned green or some other color due to a malfunction of the monitor itself. If the screen of your LCD monitor is painted in warm colors, then most likely the backlights are low. The only solution is to replace the burnt out lamp with a new one.
But still, the matrix, and not the backlight, is responsible for the color, so its malfunction leads to incorrect color rendition of the monitor. In particular, the screen may turn a certain color. Only replacing it will help.
Among the relatively light options is damage to the matrix cable. It is quite possible to replace it with another one. It’s easy to find out what gives the screen a reddish tint—the cable or the backlight—just remove the cable going to it from the matrix and turn on the monitor. If the backlight is to blame, then the backlit screen will remain reddish.
The control board may also be faulty. Just as in the case of a video card, a processor failure may occur on the monitor’s control board. In principle, this is also a curable disease with the same heating.
Cable problem
If successive changes of VGA cables had not led to a noticeable improvement in image quality, then it would not have been possible to identify the culprit so quickly. The problem was that there was not enough space on the table for the monitor, so they did this with the cable:
The rich inner world of the cable could not stand it and burst.
There is one adequate solution here - replacing the cable, and don’t do that again!
Problem with software color settings
If there is no reason to suspect the video card or anything else of a hardware malfunction, then it makes sense to reset the monitor’s color settings to default. Someone’s playful hands could well have rummaged through the screen settings. Of course, everything will be different on your monitor, but I will show you the very idea of how you can distort all the colors on the screen. Here is a slightly “collective farm” image:
It is clear that here you can creatively approach the issue of monitor color rendering. If you choose the wrong color scheme, you can then try for a long time to look for swollen capacitors on the video camera.
Or, for example, calibrate colors using the Panel Windows management. You can ruin everything there too! To verify this, you can go to Control Panel -> Hardware and Sound -> Display, then click on the “Color Calibration” link.
The following calibration wizard window will appear: 
If you compare the last two screenshots, the difference is visible to the naked eye, at least in the white areas of the window.
Also, do not forget that video card manufacturers supply their drivers with various control panels for them, for example, “Intel HD Graphics Control Panel”. Various profiles can be used here as color scheme settings. The profile can be configured in the “Display” section of this program.
So many enticing sliders!
Conclusion
This diagnostic option using an additional replacement cable and a laptop allows you to quickly discard unnecessary hypotheses.
First, we replace everything - both the cable and the computer with a laptop. If the monitor now displays normally, then everything is fine with it. Now we connect the laptop to the monitor using the old cable. If everything is fine now, then the problem was with the computer’s video card or driver settings. If the image again has the wrong colors, the problem is in the cable. However, if no replacements help, you should pay attention to the monitor itself, its color settings and its video connector.
Of course, after the initial sorting of causes, a more in-depth diagnosis should follow, identifying real problems and describing their solutions. Those. not “something with the monitor”, but for example, the wrong one was selected in the monitor settings color scheme, which was replaced with a more suitable one.

Hello. After full load The laptop monitor turns red. If you turn on sleep mode and then exit it, all colors are displayed normally. I rolled back the video card drivers to the old version - colors were also displayed normally, but the laptop was slow. And with the new drivers the color is red. Interestingly, the colors return to normal during boot and shutdown.
