Nothing, unless the unit is under warranty and they have a no-pixel warranty. unfortunately most manufacturers have a threshold of pixels that must go before they deem it warrantable. Check the Guarantee.

How do I fix dead ( not stuck) Pixels on my acer laptop? It appears like a smll hole in screen


You can't fix dead pixels, the transistor is faulty. This is indicated by black spots.

Stuck pixels remain a solid color other than white. This cane sometimes be fixed using software that flashes solid colors on the screen. Hot pixels remain solid white. this can be fixed in the same manner.

These are free software to fix stuck pixels.

I have death pixels.... can I do something with that?


Most digital camera's sensors have these so called 'dead pixels' or pixels that aren't functioning. It's normal for your camera to have dead pixels and you cannot do anything to repair it. But some cameras have a certain feature to resolve this issue, the process states that the user manually marks the area of the dead pixel and the camera will try to blend it so that it will appear to more natural. It works by blending the dead pixel to the nearest color of your image.

What does it mean by dead cells?


I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

Black spot in pictures. I checked around and somebody said it might be that a pixel went bad in the camera and he said to check the photos on the computer. It was still there when i uploaded them to the...


Most likely dead pixel on the camera. If the camera is still under warranty, you may be able to return it to be fixed (some manufacturers will not repair one or two dead pixels, check their terms and conditions). If camera is out of warranty, then you will probably just need to live with it or consider using software like Adobe Photoshop to help you fix the dead pixel(s) if it is noticeable on good photos.

Black spots on screen in the top corner and bottem of screen


how big are the black spots? are they pixel size? i have one black spot too but its called a "dead pixel" when ya buy laptops these days, sometimes...they will have a dead pixel gaurentee for like 25 dollars, but i didnt choose that so now im stuck with one annoying dead pixel on my 5 thousand dollar laptop but im fine with it i guess. when my screen gets bad, im rich enough to just replace the whole screen anyway. dead pixels cant be fixed i dont think just replaced by the whole screen.

Black spots appeared on 17" LCD Monitor-SyncMaster740N


you might have what you call "dead pixels" or a "stuck pixel" try a simple test like this one now it is not the most creative one, but it does help to see if that is the case. u might be able to Fix a STUCK pixel, but unfortunately you can not fix a "DEAD pixel" simply because it is DEAD.
try this website for simple fix instructions.
if is dead pixel what you have, if u can live with it, great, if not , it might be a good reason to get yourself an another monitor.

Good luck

Blue vertical line


The lines appearing on your LCD means it has a defect on the screen.

There are 3 types of pixel defect
1) dead pixel - pixel is always off
2) stuck pixel - pixel is always on
3) hot pixel - pixel is on but in red, green, blue or yellow, can also be a light black color

You can try to fix stuck or hot pixels but dead is dead.
1st method, flashing different colors rapidly:
JSScreenfix.com has a great tool. This is their free java applet or you can download it below.

2nd method, applying pressure to pixel:
Damp paper towel, Small stylus or dull pencil.

3rd method, tapping the pixel:
Pen with cover on or another small, blunt object.


If your laptop is still under warranty, get it replaced. If not you are looking at the most expensive part in a laptop to get replaced. (LCD screens on laptop is roughly equivalent to 40-60% of the total laptop cost

Please rate this if it this helps.

Black lines appeared on the screen


im sorry but it seems thats the screen had a dead pixel from when you bought it, the dead pixel has then since killed off the surounding pixels and they in turn have done the same. this sometimes forms a line but in some more unfortunate cases the screen can lose visual on both x and y axis's.
unfortuantly your manufaturers warrenty will not cover dead pixels as they are so common and there is a torrerance for them without doing harm, but some times dead pixels can spread.

hope this helps.

Thin rose line appear on lhs display


Kind of hard to understand your question but i think ive got it.

I believe your saying a thin red line appears going down or across your display.
And im sorry to say that i belive that your screen has lost some pixels due to a possible
drop, hit, or any other ware and tear, even over time, pixels seem to fade out and die on everything.
http://www.flickr.com/photos/53416219@N00/2110489041/ if its possibly something like that but smaller... I would bet to say it is dead pixels and is un Repairable, unless the Lcd is replaced.
