Dead Pixel on Laptop


Recommended Posts

I just bought one of those new emachines m6805 laptops. Everything is great except that I found a single dead pixel in the lower right hand corner. Is it the norm to have a dead pixel or two on a new notebook? I'd hape to exchange it only to get one with 3 dead pixels.

The definition of "broken" for LCDs is much different from what you and I (the consumer) thinks it is, when compared to what the manufacturer states it is.

As part of the manufacturing process, a small percentage of transistors that drive the pixels on and off fail due to small flaws. While this number is very low, it does happen, so the manufacturer quotes a failure rate which results in a few pixels per display (larger resolutions will have a higher number of pixels).

There are some design changes being worked on that reverse the on/off logic and design of the LCD to make failures revert to "off" (which will be less annoying than a green pixel lit up on a black screen - incidentally, green is statistically the color most complained about because it is more visually irritating). However, I believe that this is still in the 'concept' stages.

In the mean time, the best recourse we have as consumers is to have the store 'fire it up' before you buy the unit. :yes:

my last laptop had one - i returned it - new one had two - i eventually returned it - new one had one and some smearing and back light issues - i returned it - new one had a cluster of dead ones, a stuck green one, and various other dead sub pixels. returned it. no lemon policy at best buy kicked in and after two years i got a brand new laptop... twice the specs... and not a single dead pixel. couldn't be happier.

damn u...i had forgotten all about my dead pixel...i have one dead one that is like a burgundy blackish color

most place wont replace the lcs or laptop unless there is like 7 dead pixels or more...i've heard that sometimes you can lightly massage the dead pixels and it could fix em (now dont poke the screen just lightly massage it
