Dead Pixel Issue?

Hey I recently got a Westing house DWM55F1Y1 which seemed great for a long time then i noticed what i thought was a dead pixel when a bright image came up on it. Upon closer inspection i noticed that there are about 8 and they are patterned. They also flare out. Ive been trying to find out exactly what this is but cant find another example of it happening any where. Any idea what it might be? The link is a picture of the screen (hope the link works i dont typically post things like this) [IMG]http://i59.tinypic.com/29mu3hu.jpg[/IMG]

It must be really hard to get all the pixels in a large screen to be working. I've seen many with a very small number of pixels dead or stuck at one color

Ok, I have some news on this that I know you will not like, but the whole point of this site is to try and help you fix the problem, or at least, try and point you in the right direction.

The news:
I have done some extensive searching on this problem over the last month, as I have also had a friend with a similar problem that you are describing. There is a manufacturer's fault on the main power board, this has been recognised by Gateway, but as it happens inconsistantly (it may happen after a few months or a few years), they are not prepared to recall the product.

Obviously this doesn't help us as consumers that buy their products. The blue screen that you describe happens with alot of visual hardware inc. graphics cards that affects the whole market, and has now become affectionately known as The Blue Screen Of Death (BSOD).

If you are one of the lucky one's, and it is still under the manufacturer's warranty, get it sent back asap, and ask for a replacement to a similar model. If not, the only thing you can do is get it repaired or get a new/2nd-hand one.

Like I said, I'm sorry this isn't the news you wanted, but I didn't think it was fair for you to hang on.

Regards
Tim

Tiny black spot lcd


Erika, Do you mean you have a black spot on the LCD of your camera?
We call that a dead pixel. Can be black and can be white. Most LCD's sooner or later have a one or more dead pixel(s). As long as they are not in the centre of the screen you won't notice them. Even dead pixels on the camera sensor can happen. These you won't see at all, because the software does calculate what that pixel would look like in that specific shot. And the software will place a correct colour on that spot.
Try to live with the dead pixel(s). you won't see them on the actual pictures. Not on the computer to tablet and not on a print.

White spot on screen


Sounds like you are describing stuck/dead pixel.

There is no fix, it is a Pixel gone out in display panel, good chance it is just stuck and will right itself but sadly sometimes they dont and the only fix is to replace the entire display panel
Manufactures warrant such defects different depending on amount of dead pixels on screen is considered faulty, ie 3 pixels grouped or 5 separate ones .

Dead pixel


It might, somes companies won't honour warranty unless you have 3 to 5 dead pixels. Go to www.samsung.com and contact customer support to see what can be done.

Dead pixel how to resolved


Dead pixels are shame from manufacturers. They all tolerate them (you need to have more than eight for returning). Only few manufacturers talk about free of dead-pixels. One possible solution is pressing the pixel (not so hard press) and than shutdown the screen. Sometimes it will recover frozen pixel, but if you press to much, it can make another one. If you have enough for return, it will not be so bad if you have guarantee. If you are lucky to not have dead pixel transistor, this can help. But if transistor is dead, you will not success with this technique.
Good luck!

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.

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.

DSC W1 dead pixel


If it has the remapping option, it doesn't say so in the manual. from what I understand, every camera comes already with "dead pixels" and its already remapped so that you won't easily notice it. with time, more pixels drop off and you need to remap it again. Now the thing is, the remapping just makes the dead pixel an average of its surounding pixels, and there are photo editing programs that do the same thing, have the remapping option. so basicaly what i'm saying is that if you're out of warranty dont be in a rush to get it fixed. cheers

Bad Pixel in LCD (not CCD)


My camera also has a one bad pixel in the LCD; my pixel is green. My camera was also ordered from Buy.com. They have been very helpful and my story is almost identical to yours for their return/replacement practice. It is really nice to see online companies that continue to offer 'great' prices and also provide great customer support.
