When you buy a new lcd monitor and after a few days you discover broken pixels, evident because there are dots with a fixed color or blacks, it is just a nice nuisance that makes you swear. Unfortunately for some broken pixels on the lcd monitor there is no guarantee and the dealer will hardly change that screen or perform free repairs.
Not to mention the high price to repair an LCD monitor with broken pixels, both fixed and laptop ones; which then, if you take it to the official store of the brand, if all goes well, it is shipped to the factory in Italy while, if it goes badly, you will never see your laptop or screen again for at least a month.
The Pixels that make up an LCD screen are very delicate, sometimes they get damaged by fixing on a color while other times they burn out.
In this article we see how to diagnose and verify the pixels of your monitor and how it would be possible, in theory, to try to fix and repair the broken pixel via software or via the internet with online tools or even with a DIY guide .
It must be said that a burnt pixel is not serious damage and can also be endured because no manufacturer has a guarantee that it covers this type of anomaly.
The problem is serious when a group breaks that, for those who use single-colored backgrounds, they become really annoying and ugly to see as if they were spots.
In these cases, warranty repair becomes a discretion of the manufacturer who can accept if the number of broken pixels is high, but nowhere is the minimum number specified.
Before taking the monitor to the shop for repair, however, it is better to read this Pom-HeyWEB article! and see what can be done to improve the situation .
First of all, as mentioned before, it is necessary to distinguish, if it is a pixel stuck on a color (white, red, green or blue) or if it is really dead, broken and burnt and in this case, it becomes black (in rare cases even a blocked one becomes black).
If it is burnt, there is nothing to do but change it but if it is only stuck on one color, the problem could be solved via software, without starting to open boxes, through the use of some program or web application .
1) JScreenFix is a website, so without downloading anything, it allows you to repair monitor pixels when they are stuck on a color.
If, therefore, you should see points with a fixed color on the screen, open the site, launch JScreenFix and drag, using the mouse, the box with the dots, to the point with the broken pixel, keeping it for at least 10 minutes.
The box is an image that theoretically should awaken the pixel in changing color and unlock it.
2) CheckPixels is another very simple website for checking for defective or dull pixels.
To use the online tool, simply press the Check key and then, when the red colored screen appears, press the F11 key to go to full screen.
Now press on the screen to change the background color and try to locate the broken pixels.
3) Dead Pixel Buddy is a convenient site for finding dead pixels on the monitor.
4) Dead Pixel Check checks for dead pixels on the PC with five-color background tests.
5) LCD Test DeadPixel is one of the best tools to check for broken pixels, which requires you to open several browser tabs each on a different color.
6) Pixel Healer is a program for Windows PC that tries to restore the stuck pixels on a color in order to make them return to work through flashing flashes.
7) Pixel Repair is a similar program that recognizes damaged pixels and tries to awaken them.
8) UDPixel (Windows PC program) is a software used to quickly identify and recover pixels .
In the left window of UDPixel we can identify dead pixels, even those that may have escaped our eye.
Once the problem is located, in the right part of the program window, Flash windows can be created, putting a number for each broken pixel.
By pressing Start and testing the frequencies, you will try to stimulate the brightness of these blind spots, perhaps making them reawaken.
9) LCD (online application) is a tool that allows you to find and possibly repair a stuck pixel .
To try, click on the small box where "pick a color" is written and test the colors white, black, red, green and blue.
You have to remove the screensaver, put the brightness to the minimum (not black) and do not turn off the monitor with the energy saving settings then there are two ways:
- Leaving a full screen color fixed for a few hours
- Activating a whole flow of colors to stimulate the awakening of the dead parts of the screen.
10) Monitor Test Online (Tool Online) is a very thorough test, not only to identify pixels in bad condition but also to test the quality of the monitor . You can choose between three different verification methods.
Important to perform the test is to put the browser in full screen (press the F11 key).
By pressing on the first test, called html windows, you can make many checks on how the colors of the monitor are viewed, using the options in the top menu.
11) InjuredPixels is a program for detecting broken pixels which carries out a flash and color test on the screen. 12) Eizo monitor test is a program for both Windows and MAC, always portable that shows many colors in series to test and verify the image quality of the monitor.
13) IsMyLcdOK is a free program that requires no installation.
Like the previous ones, it shows many images with mixed colors and in rapid rotation that we could call a stress test.
14) Pixel check is a free Mac app to fix broken pixels.
If none of these tools can solve the broken pixel problem, as a last resort, you could, at your own risk, act manually .
There is a description of all the techniques available on the wikiHow website and Instructables .
The pages are in English but with the translation of the Google language tools you get a decent and understandable Italian.
For example, one of the quick methods is to turn off the monitor and wipe the screen with a damp cloth in the area of the stuck pixel.
We must act very firmly, putting pressure on this, however, trying not to press on others and break other pixels.
While pressing, turn on the computer and screen again and stop pressing on the pixel.
Theoretically this could work because the internal liquid that had remained still should be put back into circulation.
If all these approaches fail to fix the cursed pixel, the LCD display may actually need repair or replacement.
Please, if you are successful or unsuccessful, let me know and if you have other tips or "grandmother's remedies", do not hesitate to share!
