    My 24" Al iMac's screen is "suffering" from a stuck pixel on the bottom, just right of the dock. It's always green apart from when I move a black area over it, then it changes to black a well.

    I tried running the infamous RGB-flashing movie (and widget) for over 6 hours and the jscreenfix application for about half an hour, but it doesn't go away. I also tried the massaging technique, but that seems rather pointless on the glass-overlay.

    Anyone else got an idea how to get rid of it (it's rather annoying since I have an orange wallpaper, so it really sticks out)

    Same problem here :(
    Unboxed my beauty few hours ago, didn't think about checking for dead pixels until now.

    Found a stuck pixel, whenever the screen is black/dark there's a pixel that constatly show up as red.

    What would you do? Return it? I'm running right now, but probably won't fix it, didn't work for my macbook, damn, why does this always happen to me :(

    Stux pixels

    I'd stick with jscreenfix as I've seen it resolve many LCD problems, especially burn-in. It usually takes 24+ hours for it to be effective, though. I'd run it literally for like 3-5 days then move the window away and see if it is fixed.

    Hope you get it working!

    If it's bothering you and you're within the two-week window, exchange it.

    I discovered a few dead/stuck pixels that I couldn't remedy after owning my iMac for three glorious weeks. I took it to a genius and he swapped it for a new machine.

    Sounds to me like two sick/lame/lazy/dead sub-pixels in the same cell -- with the red and blue sub-pixels stuck at 'OFF' while the green sub-pixel continues to work normally. If that's the problem, the defect should also "disappear" when covered with an area of pure green.

    I had a similar defect on my 24" iMac. One green sub-pixel was stuck 'OFF' -- but with most backgrounds, you would swear there was a magenta pixel stuck 'ON'. The defect would completely disappear when covered with a patch of pure black, blue, red, or magenta (i.e., any color containing no green).

    I couldn't figure what was going on until I caught the little bugger "on film."

    ... BTW, all resuscitation attempts failed,

    She's really, most sincerely dead.

    Is it possible to revive a dead sub pixel? I have a green sub pixel that is always off too.
