Removing LCD dead pixels

I have found a dead pixel on what is a very young Dell laptop. It popped up today out of nowhere which is very annoying. I've heard all sorts of people finding methods how to remove it. Have any of you got any ideas/guidelines/experience from your own laptops/LCD screens on how to overcome this problem? It's quite annoying when apart from this it's a fine laptop.

Appreciate all ideas which sound reasonable/non stupid.

On my Compaq 1800 an occasional dead pixel pops up, I rub gently on the screen and it goes away. The key work is GENTLY.

I tried that but it's still there.

Are you sure you're not mistaking a dead pixel with a particle of dust that looks like a dead pixel?

Do dead pixels come alive? Surely it's not the crystal that's dead but the power not running to it.

Dead pixels are not removable by any methods that you can try
I do laptop support for HP and i see this issue everyday, i usually
send the unit in for repairs and get the display replaced, but you
would have to a certain number of pixels that are out in order to
get the service.

So these things I read on the Dell forums concerning people fixing their dead pixels are all myths?

Not entirely true, Ive worked on hundreds of lappys and sometime rubbing on the area works.

Occaisionally. I have 4 LCDs and they each have a dead pixel. Rubbing doesn't do anything.

I don't think dead pixels are fixable..

It was one of the main reasons I held back on LCD panels when I could've gotten one for a pretty good price. But I'm surprised that it would occur already; most reviews and notes I read up on about LCD's indicate that pixels dont burn out until the panels reached about 3 years i believe.

It's about time something was done about this. LCD screens have had this problem for too long. LCD panels should have higher resolutions and only use say 75% of the pixels so 25% are left for spares if others die. The more pixels on the screen the harder it will be to spot a dead on thus it will save people like Dell lots of $$$ and mayhem.

Yes and I was supposed to review this model but I told Dell that I will have to mention any dead pixels I spot. I am waiting to see what they say. This laptop is a fine machine if only the screen didn't burn up so fast. Laptops have become so fast its crazy, pity about LCD technology only focusing on brightness, vivid colors and not reliability.

I have a Toshiba Tecra 8100 that had 1 pixel stuck on red, I tapped on it several times for several days, it started to flicker and eventually became a good wholesome pixel once again. I don't know if my tapping had anything to do with it or if it would've &quot;fixed&quot; itself eventually, but it stuck out like a sore thumb, wouldn't have been covered under warranty, and I'm just glad it's gone now.

Hmmmm interesiting to maybe this will go away in a few days once the screen has done some hours of work? Perhaps its like with a new car? The engine's tight until it's going a few thousand K's on the clock.

Uh...right. So you'd just have to hope that the bad pixel was in the un-used section. That's a good way to waste money.

The reason no one has taken care of this problem is that it would significantly increase the cost of LCDs. I was told by an NEC rep that having that high of a quality check would cause 99% of all LCD panels to be counted as potentially bad, and thus not sold.

Do you even understand what LCD pixels are? They're transistors. They aren't better once they are &quot;broken in&quot;

I was referring to what Lord Gwynz said about his dead pixel disapearing.

One has to find out why they burn out, what causes it.
