How to Fix A Dead or Stuck Pixel

I recently had one of the worst nightmares of any LCD-screen owner. I have a dead/stuck pixel on the upper middle part of my LCD screen. So I quickly searched for ways to fix it.


First off, lets differentiate dead and stuck pixels.

Dead Pixels - they are black and there is no way to fix them. You just have to deal with it. That's why its called dead.

Stuck Pixel - colored white or some other color. Mine was brownish red.

Before starting, be informed that there are risks in fixing your LCD. It might cause more harm than good if done incorrectly. So manual methods are to be used at your own risk.

So here's how you fix a stuck pixel:

1. Check your warranty. If you're still covered by warranty, use it. You can have it fixed for free or have it replaced all together. No fixing needed.

2. If you're out of warranty, try software first. You can try UDPixel (Win). Its a free download but it needs Microsoft .NET framework (also a free download). Another software you can try is JScreenFix (Win, Mac, Linux). It has a free version and deluxe version. What I like about Jscreen Fix is that it is browser-based, no need to download anything. JScreenFix also claims to reduce screen burn-in.

Website instructions say UDPixel needs to be ran for a couple of hours. But if you try to use JScreenFix, their site claims to fix the stuck pixel in 5 minutes in teh first try. If the problem persists, you can try running JscreenFix for 20 minutes.


3. If software is not able to fix the stuck pixel, you can use manual methods:
(again, these are risky and should be done with care)

Pressure:
1. Turn off the screen.
2. Apply moisture to a tightly woven cloth (so not to scratch the screen).
3. Using a single finger behind the cloth, apply pressure to the area where the stuck pixel lies.
4. While still applying pressure turn the screen back on.
5. Remove the pressure and the stuck pixel should be gone.

Tapping:
1. Turn on the computer and LCD screen.
2. Display a black image, which will show the stuck pixel very clearly against the background. (It is very important that you are showing 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).
3. Find a pen with a rounded end. A Sharpie marker with the cap on should be fine for this.
4. Use the rounded end of the pen to gently tap where the stuck pixel is - not too hard to start with, just enough to see a quick white glow under the point of contact. If you didn't see a white glow, then you didn't tap hard enough, so use just slightly more pressure this time.
5. Start tapping gently. Increase the pressure on the taps gradually for 5-10 taps until the pixel rights itself.
6. Display a white image (an empty text document, or sending your browser to about:blank and going to fullscreen with F11 is good for this) to verify that you haven't accidentally caused more damage than you fixed.


Heat:
1. Turn on the computer.
2. Make sure it is plugged into wall power.
3. Go to your power settings in the control panel and set the computer not to go to sleep or standby mode.
4. Place the laptop in a partially-closed desk drawer or somewhere that is not well-ventilated.
5. Close the laptop lid almost completely, but don't let it close fully - This will keep the laptop screen turned on indefinitely. You may take a small paper pamphlet or something soft and place it on the keyboard to prevent gravity from closing the lid.
6. Let the computer sit for several hours or even days in this condition. You may check on it as frequently as you like. The heat generated will cause the liquid crystal to flow more easily into the areas that were not formerly filled.

Hopefully, these methods solved your problem. If not, you can always buy a new one.
