How to Repair LCD Monitor - Stuck Pixel

How to Repair LCD Monitor - Stuck Pixels

Stuck pixel is due to a transistor malfunction or uneven distribution of liquid in the LCD. Most often, this can be fixed. There's the Software Method, Pressure Method and Tapping Method. Feel free to try these methods to remove that annoying stuck pixel.


Before attempting to fix stuck pixels, please keep these in mind

*Don't attempt to open your monitor because it will void the warranty

*These instructions will fix "stuck" pixels, not "dead" ones. Dead pixels appear black while stuck pixels can be one constant color like red, blue or green.

Software Method

Pixel fixing software are available for free, it's not guaranteed to work but it's worth a shot

Pixel fixing software doesn't always work but it's worth a try. These software usually re-energizes stuck pixels by rapidly turning them on and off. Usually, you would have to leave these programs running for hours to get the stuck pixel to work again.

Here's a list of free pixel fixing software that you can try to repair LCD monitors:


The JScreenFix Java applet helps fix stuck pixels and image persistence on LCD screens and reduces burn-in on plasma screens. The applet runs safely inside a web browser, does not require installation and works with Windows, Linux and Mac computers.

UDPixel 2.2

DPT (Dead Pixel Tester)

It's main a dead pixel tester program but it has a pixel exerciser feature that my help you fix those stuck pixels

Pressure Method

Try this if the Software Method didn't work

* Turn off your LCD monitor.

* Get a damp (not wet) washcloth to avoid scratching your screen.

* Take a pen, pencil, or some other instrument with a focused, but relatively dull point. A PDA stylus is highly recommended.

* Fold the washcloth to make sure you don't accidentally puncture it and scratch the screen.

* Apply pressure through the folded washcloth with the instrument to exactly where the stuck pixel is. Try not to put pressure anywhere else because this may make more stuck pixels.

* While applying pressure, turn on your LCD screen.

* Remove pressure and the stuck pixel should be gone.

This works as the liquid in the liquid crystal has not spread into each little pixel. This liquid is used with the backlight on your monitor, allowing different amounts of light through, which creates the different colors. The pressure helps the liquid in the liquid crystal move around.

Tapping Method

*Turn on the LCD monitor.

*Display a black image, which will show the stuck pixel very clearly against the background. (It's very important that you display a black image and not just a blank signal, as you need the backlighting of the LCD to be illuminating the back of the panel).

*Find a pen with a rounded end. A Sharpie marker with the cap on should be fine for this. A small blunt object will also work.

*Use the rounded end of the pen to gently tap where the stuck pixel is. Don't tap too hard, just enough to see a quick white glow. If you didn't see a white glow, then you didn't tap hard enough, so use just slightly more pressure this time.

*Start tapping gently. Increase the pressure on the taps gradually for 5-10 taps until the pixel rights itself. Be careful, too much tapping can damage your monitor.

*Display a white image (an empty text document is good for this) to verify that you haven't accidentally caused more damage than you fixed.

Stuck pixel still there?

Some of my friends succeeded in repairing LCD monitor with stuck pixels by using the above methods. I'm sure it won't work in every case. It may take a few attempts to make it work.

More detailed instructions on how to repair LCD monitors can be found in this book. It's pretty comprehensive, you can even solve other LCD related problems.
