This article will show you how to fix a stuck LCD pixel that has stopped changing colors. The pixel usually hangs on some color other than black or white, and the problem can often be corrected in a couple of different ways. If the pixel turns out to be broken, and not stuck, then it will be impossible to fix it. Likewise, while you have a chance to fix a stuck pixel, there is no guarantee that you will successfully fix it.
Part 1 of 3: Getting Started
Step 1. Make sure the pixel is really just stuck and not broken
While broken and stuck pixels are often used interchangeably to refer to problem pixels, stuck pixels can be corrected, while dead pixels cannot. If a pixel has a specific color other than black, or changes its color incorrectly depending on the background color, it is most likely just stuck.
- Dead pixels usually remain white or black no matter what is happening on the screen. Despite the fact that sometimes white dead pixels are called "hot", in principle they do not differ from black dead pixels.
- If you find a broken pixel on your monitor, you will need to either take it in for repair or replace the screen. Also, sometimes (but not always) dead pixels come under the manufacturer's warranty for the replacement of the device or its screen.
Step 2. Understand how pixels work
Pixels reflect combinations of red, blue, and green, depending on what is shown on the screen. Pixel can get stuck for a variety of reasons, including using the monitor for too long or after displaying too saturated colors for a long time. When a pixel is stuck, it only displays one color, which may vary slightly depending on the color of the surrounding pixels.
Again, a dead pixel never changes color regardless of the state of the surrounding pixels
Step 3. Check the warranty conditions for your LCD monitor
Often, manufacturers are ready to replace a monitor when a certain number of stuck or dead pixels are observed on it. If your monitor is still under warranty, it is best to take advantage of a warranty replacement rather than trying to fix the problem yourself.
Nevertheless, in this case, you can try to use the software, as this is a non-invasive method of influencing the problem
Step 4. Turn off the monitor for 24 hours
If the pixel is stuck recently, then the problem may disappear by itself - just turn off the monitor for a day. There is no guarantee that you will fix the monitor in this way, but the presence of a stuck pixel often indicates that the monitor has been used for too long and it is best to turn it off for a while to prevent further damage.
Unplug the monitor completely
Step 5. Consider taking your monitor for repair
Even if your monitor is out of warranty, paying for a professional repair will be cheaper than buying a new monitor due to accidental failure of the device as a result of self-repair.
Step 6. Know that a pixel can work on its own
It is not uncommon for stuck pixels to disappear after a while, however, this period can vary from a few days to several years. If you have only one pixel stuck on an expensive monitor, it is better to refrain from tapping, rubbing and other physical impact on the monitor in order to fix the pixel.
Part 2 of 3: Using software to fix screen problems
Step 1. Understand how this method works
Screen repair software shows random combinations of red, green, and blue tints at up to 60 flashes of color per second to bring the pixel back to its normal cycle.
- There is no guarantee that screen repair software will solve the problem successfully, but it is usually effective in more than half the cases.
- There are both paid and free programs for recovering monitor screens. That being said, free programs are just as effective at fixing pixels that can actually be fixed.
Step 2. Stop using stuck pixel repair software if you have epilepsy
Since this software displays random flashes of rapidly changing colors on the screen, you may want to stop using it if you (or someone in your family) have epileptic seizures.
Step 3. Go to the JScreenFix website
Go to http://www.jscreenfix.com/ in your browser. JScreenFix is a free online application that can fix stuck pixels.
Step 4. Scroll down the page and click on the Launch JScreenFix button to launch the application
This button is colored blue and is at the bottom of the page. It allows you to open JScreenFix in your browser.
Step 5. Find the stuck pixel
The main part of the screen will be black, so you can easily find the stuck pixel.
If the pixel is not in the black area of the application window, press F11 to go full screen. You may have to hold down the Fn key first to press F11 unless the browser goes full screen when you just press F11
Step 6. Move the flashing app repair block to the stuck pixel
Click and drag the flickering block over the problem pixel, then release.
Step 7. Leave the application running for at least 10 minutes
In this case, do not roll up the window, move the repair unit, or turn off the monitor.
If possible, leave the application running for an hour
Step 8. Check the state of the pixel
When the required amount of time has passed, close the application window to check the pixel. If the pixel is restored, then the problem is solved.
If the pixel is still there, try turning off your monitor for a day and then using the same method again. You can also try to restore the pixel with heat and pressure, but this is not recommended
Part 3 of 3: Exposing the Problem Pixel to Pressure and Heat
Step 1. Understand the risks associated with this method
Although some people have been able to fix stuck pixels with pressure or heat using this method, you would rather damage your monitor screen than fix it.
Another problem with this method is that it voids your warranty
Step 2. Turn on your computer and LCD monitor
The monitor must be turned on for this method to work.
Step 3. Open the black image
It is imperative that the screen is actually showing a black image and not in a no signal state, as you need the LCD monitor to have its internal backlight working.
Step 4. Find a thin object with a narrow blunt end
A marker or pen with a pointed cap, a very blunt pencil, a plastic stylus, or the back end of a makeup brush should work for you.
Please read the warnings at the end of this article before moving on. Physical friction can aggravate the condition of the monitor screen
Step 5. Wrap the end of the selected item with a napkin
This will prevent the monitor from being scratched.
If the object can pierce the napkin, then it is too sharp. Find something else
Step 6. Use the rounded end of the object to gently press down on the stuck pixel
In this case, a white ripple effect should appear around the point of contact.
Try to put pressure on the stuck pixel without affecting the surrounding area
Step 7. After a few seconds, remove the item
If the pixel remains the same, you can reapply this method or switch to using heat. However, if the problem is resolved, immediately turn off the monitor and leave it off for at least one hour.
Step 8. Dampen a washcloth with hot water
If possible, heat the water on the stove until the first signs of gas bubbles at the bottom of the container (about 88 ° C), then dip a washcloth in there and soak it in hot water.
Step 9. Protect your hands
In order not to burn your fingers in the following steps, use an oven mitt or a thick napkin.
Step 10. Seal the hot washcloth in a zip-lock bag
This will protect the monitor from moisture. Make sure the bag is securely closed.
Step 11. Attach the washcloth bag to the stuck pixel
Light pressure through the washcloth should loosen the pixel content a little, potentially helping to correct it.
Never apply the packet to a pixel for more than a few seconds at a time
Step 12. Check the state of the pixel
If the pixel is restored, your job is over. If not, you have no choice but to contact a professional service center. So either have your monitor repaired or let the pixel recover on its own over time.
You can also try using special software again to restore the pixel
- If the recommendations in this article do not work for you, try replacing your monitor under the manufacturer's warranty. If your case falls within the terms of the warranty replacement, contact an authorized service center to discuss possible options for further action.
- You can purchase specialized hardware that can correct stuck pixels and calibrate your monitor. For example, PixelTuneUp OEM is one such device, but other devices can also be found on sites like Amazon. These devices can be used to customize TVs and other LCD screens.
- Do not try to disassemble the monitor. This will void your warranty and the manufacturer will refuse to replace the device.
- LCD screens are composed of multiple layers. Each layer is separated from each other by the thinnest glass layers. These layers are themselves separate, very fragile layers. Rubbing the LCD monitor with your finger or even a tissue can break the glass and exacerbate the original pixel stuck problems. Basically, in most official service centers, certified workers are prohibited from rubbing and tapping screens to fix pixels. Use such methods at your own risk.
