identifying dead pixels

[Christo]

ok dont hate me for what im about to say

i recently purchased a packard bell notebook.......

it isnt a bad notebook, centrino 1.4ghz, 512mb ram... 64mb int graphics
(only real downer)

mainly got it for work at uni it has a 802.11g wireless onboard which i have
heard is better than the PCMCIA cards because onboard has an aerial around
the monitor... anyhoe to my point


i figured that me being a compotent PC user i wouldnt crap up a PB notebook
and would be able to manage it myself, no serious unidentifiable hardware
problems or stuff after checking out the hardware it isnt bad

the notebook is an easynote E4 series

the hardware isnt bad as i mentioned, NEC board, samsung memory, samsung
hard drive and NEC dvdrw

problem is one pixel on the screen is blue... i have only had the notebook
about 2 weeks, but there is now a pixel on the screen that is constantly
blue, it only appears blue on a black background though, on a white
background the pixel isnt blue, it appears normal, same with any other
colour background

now i have just turned off the notebook and switched it back on after 15
minutes of leaving it and the blue pixel (dot) appears to be gone, twice
this has happened

so.... what is this poblem?

is it a dead pixel? or just a pixel that is a bit drunk sometimes and
decides he would rather be blue on black backgrounds?

any help much appreciated

thank you

This is an intermittent pixel, if it comes and goes, as you are describing.

Most monitor manufactures have a dead pixel policy. Most are specifying that
there must be more than 5 defective pixels before they would exchange or
service the screen.

I have seen a fair number of LCD screen with dead pixels. Sometimes they can
be lit, partially on, or black. When they are black, this is not as
annoying.

I have an Acer laptop, with 2 red defective pixels. These are partially on,
which is not too bad. Most of the time, I never notice them. I also have a 3
year old LCD screen that has about 3 dead pixels in a row. These are showing
as partially lit in white.

I have some clients where they have a few Viewsonic 20 inch screens with a
few dead pixels in each of them.

This is all in part of owning an LCD screen. There are some high end LCD
screens where they are guaranteed to have a zero dead pixel policy. But, one
would have to be prepared to pay their asking price.

Whatever you do, don't ever press your fingers on the LCD screen. These are
delicate, and will be very easily damaged. Even wiping your finger too hard
on the screen can damage the surface.

You've just outlined very nicely some of the main reasons why I stay
the hell away from LCDs!
