Is it possible to eliminate (turn off) dead pixels in LCD monitors?

[Boris]

Hi,
I guess the subject is quite explanatory. I have an LCD monitor which
has a dead pixel in bright purple right in the middle which is very
annoying. Is there any software that could turn off a pixel at a
certain coordinate? I would even prefer having it black instead of that
annoying purple.
Thanks,
Boris

 

[Michael Kennedy]

probably not since a dead pixel is one that is not working.

Actually I was hoping to turn it off (black etc). I know I may be
dreaming but at least I'd like to know if it's technically possible.

If you could control this pixel it would not be dead

Simple !!
Just cut a pixel sized piece of black tape and stick it on wherever needed.

Dead probably means it's not responding at all.

If the monitor is new, that's probably covered under warranty.

Say what you like, without duct tape I'd quack up.

I worke breifly for a "reputable" automotive and automobile alarm firm
back in the 70's. The owner of the firm owned a Cadillac that he wanted
to sell. Unfortunately the idiot light for the engine over temperature
would not go out. My project that day was to kill that light for him!

... or a charred remains of a pixel that was fried by one of Sam's
lasers!

Always-on pixels are more annoying than always-off ones. I wonder, too,
if there is some way to short-circuit such a pixel and turn it
permanently off. Intuition suggests that this would be easier than
restoring it to normal function. Unfortunately I have no other ideas
right now.

A friend of mine told me about a process used by a very popular
night-vision optics manufacturer to convert bright dead pixels, which
are very undesirable in military applications, to dark dead pixels,
which are more tolerable. This is a totally different kind of display
technology, but it shows someone else is sharing this point of view.

There is a great deal of documentation on the web describing how tft
panels are constructed and how they operate. Maybe you can get some
ideas from there.

I used to work for a Till company and the memory cmos had a non rechargeable
battery to retain the memory , which used to flash a light when it was flat
,the quick bodge by most was the black tape fix over the hole ok until the
first power cut then no more program

What happens to the thousands or millions of such monitors / TVs returned to
manufacturer's ?

Right, but it could be dead lit or dead black. He wants to convert
dead lit to dead black. Sounds like a job for a Sharpie!

Depends. From what I've seen, many screen manufacturers have started
requiring a certain number of dead pixels before a monitor can be sent
in -- like 5 dark dead pixels or 3 lit dead pixels, something like
that.

As for what happens to any returns, my guess is that the ones with
just a defect or two get resold under a different name and a different
warranty, one that does not permit returns for just a few bad pixels.
The ones with more defects either have the LCD screen replaced, get
sold cheaply as having `slight blemishes' or just get scrapped.

Sad to say, Sam, most LCD warrantees don't cover the case of a single
dead pixel. They consider that the device (the LCD screen) has not
failed unless a certain number of pixels are dead. The number varies,
but on my LCD TV, the warranty doesn't kick in unless there are (I
think) eight dead pixels.

Depends, in Australia unless the seller specifically informs you at the
time of purchase of the manufacturers stance on this, (Pixel warranty),
then it's your right, (ie. for once the consumer laws work for you), to
return it to the place of purchase for replacement/refund.

An article from a PC mag can be seen here:

If your consumer laws are as sane _and_ the monitor is under warranty
_and_ you weren't informed of the Dead Pixel Policy then you have a case
for refund/replacement/repair.

Similar story with plasma sets:

Those interested should check the "Manufacturer's General Warranties and
Dead Pixels Policies" link on the above page. Chances are you won't be
getting a "perfect" screen for that premium price, folks.

I haven't yet come across a dead pixel on a plasma set, but then I
haven't seen nearly as many of them as I have LCD displays of one sort
or another.

And if you are unlucky enough to have the dead pixels clustered together
you are really screwed.

I saw one on a Pioneer plasma set in a store a few years ago. It was
bright green and flashed randomly.
