Very true, its called a dead pixel and the PC and TV industry allow a few to go by with a couple of them visible...nothing can be done, just NEVER buy Protron again, they are the worst on-going maker of "electronics" that I know of, as I have had 2 of the 32" units die in a tad over one year...take care CDM

One pixel is not repairable unless the plasma dislpay panel is replaced. That would be too expensive for that.

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.

A black _ in the upper left hand corner (size of underscore)


It is what we call a "Shatted Pixel" and you can fix it by flashing your screen

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.

Blue Noise, left side of TV


I have the same problem -- had a Best Buy technician out 4 times so far, replaced 2 parts, adjusted the voltage, etc., but still have the same problem -- looks like there may be no solution other than replacing the TV, which is an expensive proposition considering that mine is about 18 months old.

Blue Noise/Pixels Bottom Left Corner of my Samsung Plasma


You would need to have a technician remove the back of the TV and make the adjustment. There are 2 small adjusters that they change to adjust the voltage.

Monitor is black and blue light flashing


Boot from safe mode and try a different pixel/color arrangement. Obviously a lower pixel and color setting.

Blue snowy pixel areas on my plasma


some of these panels were mis-calibrated from the factory after not aging long enough. Let the TV run for atleast 2 hours and adjust the Vs and Vscan voltages. When it is blue in the left I have found generally the Vs is about 10 volts too high.
