Stuck pixel comes and goes

[iMetalG5]

Just curious, on my iMac I have ONE stuck green pixel that flickers. Sometimes it just goes away and sometimes its bright as day and sometimes it flickers. When i take a bottle of compressed air to it (shoot air directly onto the stuck pixel) the green pixel flickers and then goes away. Sometimes it just keep flickering and other times its gone for a few days only to return.

So what is up with this stuck pixel? Anyone else experience this?

It works. Ive done it successfully on the Dell LCDs at work. Not always, but Id say 85% of the time.

Put one hand behind the iMac for support, and then with a very soft rag, GENTLY rub the pixel with a knuckle in a circular motion. Now when I say gentile I mean GENTLE. Its possible to damage other pixels with too much pressure.

"massage the dead pixel alive"?

for those well versed in electronics, can you explain how this works? i believe it works, since some of you have already done it, i just want to know how....
