UPDATE: This Instructable was on Engadget! http://www.engadget.com/2007/12/24/how-to-guide-details-fix-for-stuck-pixels/
I am going to show you how to fix a stuck pixel on your LCD monitor. Stuck pixels are really annoying and just plain look bad. Over the past few years I have had to fix SO many stuck pixels. It's not that hard to do and usually only takes a couple of minutes. Enjoy!
This will only work on LCD monitors, but this includes computer LCD monitors, laptop screens, cameras (the screen might have a hard protective shield over it that you will have to take off), and hand-held systems (will most likely have a hard protective shield). Does anybody know if this will work with an OLED screen? I think that it will, but I'm not positive.
Note: This will only fix stuck pixels. Not dead pixels or hot pixels. A dead pixel is when the pixel is always off. It is easiest to spot a dead pixel against a white background. The pixel will appear to be non existent. It will look darker than the stuck pixel in the image below. A hot pixel is when the pixel is always on. It is easiest to see against a dark background. The pixel will be bright white. A stuck pixel will usually the red, green, blue or yellow, but can also be a light black color (pictured below). A stuck pixel is caused by a manufacturing defect in which it leaves one or more sub-pixels permanently turned on or off.
By the way, the picture that I took is a bad example of a stuck pixel. Because it is black, one might think that it is actually a dead pixel but it is not. It just so happened that all of the sub-pixels in that pixel were permanently turned off. The next time I see a dead pixel on a computer that isn't black, I will update the picture because the current one is a bad example.
PS: This is my first Instructable so please be nice. :)
Step 1: Materials
1st method, flashing different colors rapidly:
JSScreenfix.com has a great tool. This is their free java applet or you can download it below.
2nd method, applying pressure to pixel:
Damp paper towel
Small stylus or dull pencil. (I used an odd looking stylus from a board game)
3rd method, tapping the pixel:
Pen with cover on or another small, blunt object. (I used the back of the same stylus)
Step 2: First Method: Flashing Colors Rapidly
Open the java applet and resize it so that the window is very small. Now move the window over to where your stuck pixel is. Leave it be for five minutes than close the window and see if it's fixed. If its not than repeat again for another five minutes. The site says that it may take up to 20 minutes but I have found that it usually works within the first 10.
PS: Beetlegossip suggested that you could also go into Notepad in Windows and then create a batch file and write this,
I have not tested his batch file method yet (I have a mac) so please tell me your results. And obviously the batch file method will not work for macs.
Step 3: Second Method: Applying Pressure to Stuck Pixel
This method works because a stuck pixel is a pixel in which the liquid in the liquid crystal has not or not completely spread to this pixel. The backlight uses this liquid and lets different amounts of light through. This affects the color of the pixel. The pressure helps the liquid in the liquid crystal move around.
Step 4: Third Method: Tapping Monitor
I believe that the reason this works is the same as method 2.
Step 5: Enjoy Your Now Flawless Monitor!
And as I said before, this will obviously only work on LCD monitors.
