    I had an area of dead pixels on my Lenovo laptop, which appeared out of nowhere and grew over time. The area was completely black - couldn't see through it, and after recent travel with laptop - I noticed that area turned green, and I can see black and other darker colours through it. Could it have magically partially healed by airport scan? or any other causes?

    LCD = Liquid crystal Display. http://en.wikipedia.org/wiki/LCD

    Some issues with LCD display can be the Liquid itself. The sun beating down on it, pressure differences , just things that would effect the liquid in them.

    If you have ever heard of the "Rubbing" a bad pixel out , it was all about moving the liquid around to try and get it working again. It does not work for pixels that are "dead" electronically but it may change things for pixels that are "dry".

    All the ways that liquids could have moved in your travels, could be what changed the . . . liquid.

    Any way to fix a "dead" pixel in an LCD screen?

    I have an older LCD monitor, and it has recently developed a single green pixel that's always on. It's not really annoying if the screen is bright, but it's very noticeable when there's something dark on the screen.

    Is there any way to fix this?

    JScreenFix might be worth a try.

    Some references that discuss on pixel problems.

    Your dead pixel might actually be a stuck pixel.

    Wikipedia: Stuck pixels, unlike dead pixels, have been reported by LCD screen owners to disappear, and there are several popular methods purported to fix them,[9] such as gently rubbing the screen (in an attempt to reset the pixel), cycling the color value of the stuck pixel rapidly (in other words, flashing bright colors on the screen,) or simply tolerating the stuck pixel until it disappears (which can take anywhere from a day to years). While these methods can work on some stuck pixels others cannot be fixed by the above methods. Also some stuck pixels will reappear after being fixed if the screen is left off for several hours.

    Either way, it seems like there are several possible techniques you could try to fix this.

    • Pressure method
    • Tapping method
    • Heat method

    This howto shows these techniques step by step and has a good explanation of the process. Hope one of these techniques can help out

    There are several several software-tools you could use to remedy this as well.

    you can try to re-seat the edge connector to the LCD display if you dare take it apart. The prognosis is not good however. In many cases there is no way to fix this kind of a problem, but sometimes you get lucky. So don't be afraid to try if you are comfortable with this level of complicated dis-assembly and re-assembly.

    I've read if you "knead" the pixel when you turn on the monitor, sometimes its wake up the pixel.. But i have two dead pix on my screen and a lot of massages after... They are still dead...
