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)
