How to kill pixels on LCD screen?

[DST]

I have a LCD panel with a defective pixel (big fat red pixel, very annoying and makes it impossible to watch movies or work under a Linux terminal). However, the manufacturer requires 5 dead pixels before they will replace the screen.

How can I kill 4 more pixels?

Can I use some special fast-chaning pattern displayed on the screen? Would simply smashing the screen hard kill more pixels? Can I use a magnet or something? Would heating it up kill more pixels? Is there anything else I can do to ruin the screen but make it look as if it was faulty from the start?

When paying $600 for something, I expect it to work. I can't think of any other items that can't be returned if you find them defective.
Just imagine if you compute keyboad had severa andom dead keys...

or if your computer would randomly crash because the CPU had a couple of dead transistors?

Even most decent harddrive manufacturers will replace the harddrive if you find a bad sector on it.

YOu might be able to return it and buy some others monitor or the same one later on...

I can guarantee that jabbing the screen with a sharp object really hard will cause dead pixels.

The "pin" method is the most sure fire way to kill pixels. It is also dead obvious with a magnifying glass. This is def. not the way to go about this, assuming you should be going about this at all . . .

Some people have said that gently rubbing the bad/dead pixel might fix it. You could try that.

Have you call them and asked if you could exchange it? Or are you assuming that you can't? It seems like returns/exchanges due to dead pixels might be examined closely since LCDs are expensive and they want to check to make sure that its really a defect.

If you did call them about ONE bad pixel, they probably have a record of the call. So, a second call complaining of more bad pixels might be suspicious...

Allthough IDK if can complely agree with what you are doing, I do agree with you that if you spend $600 on an item then it should be perfect, if not it should be returnable. Not none of this must be a certain number of faulty componets. If they cannot manufactor it without defects, or are unwilling to accept them back, they should not be manufactured till this is resolved.

Yup, my lappy's screen had a stuck subpixel (that's when the pixel only displays one color, dead pixels just don't shine any color). After twenty seconds of rolling a q-tip over the offending pixel, the red eyesore disappeared before my very eyes. It took more pressure than I expected, but it's been several months and it still works fine. Although as I said in the thread in GH those months ago, I take no responsibility if the silicon layer cracks and ruins the display
