What is a stuck pixel?
A pixel that is "stuck" displaying a certain color (red, blue, white, green).
What is a dead pixel?
A pixel that is always black, is probably dead.
Are there risks while repairing?
Yes.
You may just create more problems, while trying to fix that stuck pixel.
All of these are possible.
> Smudging the anti-glare coating, especially if you use your finger instead of a cotton swab (q-tip).
> Removing the anti-glare coating, if any.
> Damaging the thin LCD screen (haven't seen this reported yet)

Massaging didn't work for mine either, however about 20 seconds of "rolling" with graduating pressure and a q-tip (a.k.a. cotton swab) whipped the red subpixel back into shape. That was one time about a year ago and it has never returned.

My LCD has one white dead pixel that came shipped (meaning it's there from the very beginning). And a red pixel developed after about 3, 4 months. I was able to rub the red one away, although it does come back from time to time, but not very often. The white pixel does not go away at all, fortunately it's near the corner and only noticeable when I look for it.

This actually works I cannot believe it. I had one dead pixel on my 191t , and I tries this with a q-tip and it worked. Samsung actually said to do this, but I thought it was bs at the time. Man you really have to apply a lot of pressure though. Do not be afraid to push hard.

i had one stuck blue pixel on my hot dealed mitsubishi NXM56LCD 15" $200 AFR. it was located in the upper right corner. when slight pressure was applied the pixel would function. i thought that could only be a good sign, and i went thru with it. after 15 minutes of slight swirling pressure, it started to flicker. i was worried at that point, since a flashing pixel is far more annoying then stuck pixel. over the next few days the flashing slowed down, from once every 10 seconds to minutes at a time.(staying black, then flashing to blue) after about 3 days, it stopped flashing. now it works perfectly and passes the nokia and monitors direct tests. it's been about a month later and no reoccurrences. i'm satisfied thats it's passed my test as a slick computer trick.(along the lines as paperclipping a ATX power supply to turn it on, test it.)

Hey AT'ers!
I've had this 17" GatewayFPD1530 LCD i bought at a PC show and i was dissapointed to find it had 3 dead sub pixels.
2 pixels always showing red in the center, and 1pixel showing a lightblue/gray in the center. Well anyway i was gettin real annoyed by the dead pixels today so i tried pushin on them and "massaging" them.
I had to apply alotta pressure but it actually worked!!! So far it's been about an hour and theve been gone. I heard this somewhere, and i forget where. But you have dead pixels give this a try.

W00t w00t! Thanks for the tip man, I hadn't thought of Q-Tips, and I'd tried this procedure on the ol' lappy's annoying stuck sub-pixel that was in the center of the screen with a cotton cloth and fingertips to no avail. But I just used a Q-Tip and applied more pressure than with the cloth (with some restraint though) because I wasn't afraid of killing other pixels with the small surface area of the cotton-balled Q-Tip, and after about 20 seconds of slowly rolling it like you suggested, it disappeared before my very eyes and it is still working great!
Congrats on the "triple bypass" OverVolt
