LOL, it's a mystery, lol. Well, im guessing that there is a small fault with the monitor. Each pixel is regulated by voltage to gain the differnt colour outputs, so perhaps this pixels voltage reg had a blip or is on its way out verry slowly.
 
Or some dead pixel can re-life back , like on the psp there a video that you can play when ur deseperate to try to wake them up.
 
there is a sort of "burn-in" period for lcd screens. some pixels can fail in this time and some can start working properly again as agashka said.
its a common issue with this type of screen and the manufacturer will often have a tolerance for dead pixels
 
Yea it really is not that amazing. It seems you had a "stuck" pixel and not a dead pixel.
 
Yeh, it's important to note the difference between a dead pixel (black) and a stuck pixel (one colour stuck on). Dead pixels have no chance of recovery, but stuck pixels (like you have) can sometimes be revived. You can try to revive it yourself by rubbing it with a cloth for a few minutes.
 
As Chef from south park might say, all you need to do is treat your screen like a woman, tenderly rubbing it in just the right areas and waiting for it to come to life...

Ahem! - Yes, I have a pixel that sticks when my monitor's cold, they're not uncommon, just quite annoying.

Yeh, apparantly it can work, if you google it you'll find a lot of success stories. As agashka said, there's also a video you can download which will rapidly flash colours on the screen. The only one i've seen is designed for a PSP, but some people have reported success using it with an ordinary LCD screen (which makes sense, given that it's pretty much the same technology). I've also heard, though, that rubbing it can actually make it worse, although this was on a forum, so whoever said it may just have been trying to scare people!

For anyone who wants to try the video, here's a link: http://www.macosxhints.com/article.php?story=20050913120036269

At work there was a laptop someone brought in a few times(completely stupid people, ask me later if you want to know :P) Anyway, there was one point on the monitor where something apparently hit it and a few pixles had gone out. I began rubbing it with my finger and a few of them came back to life. One would flicker white to blue(the background) but it got a few to come back...

Yes you can revive a stuck pixel this way. However I would be very careful doing this as you just may damage not only the stuck pixel permanently but all and any pixels around it. You would be putting pressure on more then just that one pixel after all which is something you normally should not do.

So it is good advice and yes you can fix a stuck pixel this way it is also important to mention the dangers.

Edit:

I read further and you mention this.

Believe it. It is equally good advice to follow as the advice you had left here about rubbing the stuck pixel. When In doubt google it :).

True, personally i'd try it if it were my monitor, but then I can't speak for everyone. Obviously you don't want to press too hard but it can work.

The unfortunate thing when googling it is that there's no way of determining the reliability of those citing the dangers and benefits, particularly since i've never seen a guide on this, only posts on forums. As such, there's no way to know whether the people who are having problems are pushing too hard, or in some other way abusing the monitor, or if they're just lying (and i've seen more than one obvious lie!).

Yes, it's potentially dangerous but there's no way to know the percentage of people who have had sucesses vs the percentage who have damaged their monitor.

The video may be a safer start, but even with that people have reported damage to the monitors.
