a "dead" pixel is much different than a "stuck" pixel.
I don't know all the terminology or technical synopsis for what the difference is, but I do know that a stuck pixel maintains at least one color, though fails to display any colors that incorporate another part of the color spectrum (rgb) properly.
I just got a new monitor for Christmas this year, and couldn't take my eye off a certain stuck pixel in the center. I also stumbled upon this application, let it run during dinner one night and the pixel hasn't had a problem yet.
for old plasmas, all it does is more uniformly burn in the phosphor on the rest of the entire screen. over time your plasma will be washed out. (years) According to wikipedia (and others) newer sets suffer from a less permanent characteristic; "polarization".
via wikipedia http://en.wikipedia.org/wiki/Plasma_display#Pros_and_cons
"Older panels were notoriously subject to burn-in, although due to improvements in phosphors, in modern PDPs the effect is largely caused by polarization of the gas particles and can often be reversed by leaving the screen on a "snow" or static channel for an hour. Some home theater afficionados claim that, while burn-in is less likely now than in the past, it is still possible in some circumstances, and many plasma televisions have functions (such as "orbiting", in which the image is periodically moved imperceptibly) to minimize the problem. In any case, LCDs are not susceptible to permanent burn-in."
Gets. The * is an emote and implies himself. As in, "avihappy maximises window", "avihappy gets epilepsy while staring at screen", "avihappy falls to ground"
Taedirk, I am pretty sure that by "Gets epilepsy?" Metsfan is referring to the fact that you don't just get epilepsy from watching flashing lights, it's a chronic condition that is triggered by flashing lights, not caused by.
Hmm, I've got an LCD TV with some stuck pixels near the bottom where my 3 year-old decided he was going to "clean" the TV and sprayed vinegar/water mix all over it. Going to have to hook my laptop up to it and try it out, see if it works.
Seems to work. I work for a school district in the technology dept and sometimes screen vendors send us programs that work very similar to this when we complain about batches of monitors with lots of stuck pixels (we just call them dead pixels, though).
No luck on mine, but I've only done it for 20 minutes or so. I can't really leave it on all night as it's in my room. By the way, is there a difference between how to fix dead and stuck pixels? I'd assume dead pixels are permanently dead, but I could be wrong.
I also bought myself a Samsung 940BW and have this friggin stuck pixel relatively center in the screen! Software and pressure doesn't work for me. This pixel shows different coulours depending on the picture on the screen, so it isn't dead is it?
Apparently Samsung has a policy that 4 dead pixels guarantee a return. So either I fix this one, or I find a "how to kill pixels" forum to try and kill 3 more
I had a few stuck pixels and tried UDPixel (mentioned above) when it was on digg about a year ago. Left it on for at least overnight and no results. I just ended up buying a new monitor since the prices have come down so much.
i think most DS come with a stuck pixel, there is a version on the website for PDA's and such, but you would need some kind of flash card for the ds, maybe with one of those adapter things you see on the DS ROM websites, even then i dont think the ds could run the program, somebody told me nintendo will fix it for free anyway.....
Here's a way to fix the pixels on your ds but you need something to put it on, I used Max Media player for ds that I found at Wal-Mart, didnt work for me but its worth a try. http://homepages.ihug.co.nz/~kplchow/homebrews/
Nintendo has a no tolerance policy on dead pixels. If there is even ONE on your DS screen, you can send it back and they will replace it. They're one of the only companies that are good about that kind of thing.
I've fixed stuck pixels on three different monitors. I just scrape it with my fingernail covered with a thin cloth. Sometimes you have to work at it from different directions. If it's "dead" it's usually gray and it won't repair with this method. It's worth a try though, I got a gray one to work once. It must have been stuck in gray. Had a helluva time with a pink one!
I bought an LCD monitor at Best Buy and tried both the software and the hardware (i.e. finger) method to fix it. The solution that actually worked? Took it back and exchanged it within their 14 day no-hassle policy (*and* asked them to check the replacement in-store so I wouldn't have to drive across town again to replace a second defective monitor). Replacing the LCD, if it's an option, is the *only* surefire way to "fix" stuck pixels.
I'm curious about how this can fix burn-in. I thought that was permanent deterioration of the phosphors at those locations, and the only fix I can think of would be to display a negative of the burned-in image for a sufficient length of time. This would burn the unburned pixels and make it all equal.
Actually, they probably mean "screen retention". Burn-in is usually irreversible if done by user stupidity (not adjusting the white level; how hard is it people really).
Either way, after a while phosphors can wear in a certain area yes. However, aging all the phosphors equally again for a time span can undo basically what was done. That's why most have a built in white screen. In other words, you're taking a solid screen and burning it in which will slowly overtake the previous one assuming no damage was done (see comment about white levels), though depending on how long the static image was on for it may take very little to an extremely long time.
However, if you're smart you shouldn't need to do this to your plasma. Wait until AFTER the break-in period to play games and for Christ's sake CHECK YOUR CONTRAST!
agree with you there dreamlayers. Burn in pixels have 'aged' more than the surrounding pixels and have lost intensity thus a static images are 'retained'
"Remember, there is a difference between a DEAD pixel and a STUCK pixel. These Apps will not help with DEAD pixels. If You push Your finger lightly on an LCD screen, and it doesn't budge - You may have a DEAD pixel."
O M G, I just did that and it moved lol, I'll put this on when I go to bed, and see if it works.
I tried this. Had a single stuck red pixel for a couple of years. Used undeadpixel for about 24 hours. Nothing happened. Months later I read on digg someone saying to press it a few times with your finger. I thought it was a joke, but tried it anyway, feeling kind of silly. Then as soon as I stopped pressing it, while I looked at the stuck pixel, it became unstuck. I don't know if using undeadpixel had anything to do with it - I suspect just pressing the pixel will often work.
I ran this for on my Panasonic Viera HD Plasma and after about 10 seconds of stressfully running, my screen flickered and now has a 2" line of black down the center!
It seems as though no one else had the same issue so it was probably more an issue with my monitor, but I wanted to warn people.
Thankfully it is only six months old and still under warranty.
Has anyone else tried to use any programs on a plasma? I have a Toshiba 42hp95, it's warranty just expired last Thursday and this morning a purple line about 6 inches long by 1 pixel wide appeared in the upper lefthand corner of the screen. Does anyone have any good advice?
Did you find a resolution to your issue? I have the same model TV (Toshiba 42hp95) and I just got a line of stuck pixels on the upper left hand corner of mine. It sounds just like what you've described -- 96 dead pixels in total in a repeating pattern of purple, space, purple, white, white, space, space, "Repeat again until 96 pixels total". I'm truly *****. I've had this tv about 1.5 years and love the picture. But this streak at the top of my tv might drive me nuts.
Today at our local PC Medic I noticed in their clearance section a brand new Viewsonic 19" VX922 obviously returned from a customer (skuffed up box).
I'm in the market for a used 2nd monitor to use on my old P4 so I asked what was wrong with the unit and what was the price?
The desk lads brought out a tech from the back room and he explained that the unit had a dead "RED" pixel screen centre.
A good customer had insisted on returning the unit but as the single pixel was within the Manufactures quality control specs, Viewsonic had refused to authorise return.
The store had given the customer a new unit but was stuck with this "custom order'unit.
With some haggling I got the price down to $170 bucks Can (around $135 US) but first checked prices after at Staples.
Their "clearance" price on the unit is/was $369.
So I bought it and I'll say that Red pixel is a pain in the butt.
So tonight I looked around and read this thread.
"Use your fingernail and a wet cloth and gently rub"
Okay I did that then got lasy and just wet my finger and rubbed and rolled around the pixe;.
After 2 minutes the red pixel started flickering off and on (normal color) and I kept on.
Right now the red pixel is gone.
It seems to be working perfectly.
I don't know how long this is gonna last but right now I'm as happy as hell and can't wait to tell PC Medic.
I am having the same trouble as jusbao. I have a Toshiba 42HP95 and it randomly, after a years use, has a greensih/white line about 6 inches long by 1 pixel high . Not sure what may have caused this. Any ideas or anyone else having the same trouble?

Amazing! I've been living with a bright green pixel in the middle of my screen for months and this thing fixed it in no time. Just amazing. I thought I was screwed...who knew? THANKS VERY MUCH TO THE AUTHOR!!
