Stuck Pixel????

[Rossl]

Just bought a new LCD monitor. Viewsonic VG930M. Right out of the box there is a small bright green dot that does not go out. I assume this is a stuck pixel. I called Viewsonic and the suggested that I run this download to "UN-stuck" the pixel.

Did anyone here ever use this?

I really feel like returning the monitor but now shipping is going to cost me another $35-40 round trip.

I've run the above mentioned "fix" for about an hour. The dot looks a liitle less bright (but maybe I'm just getting used to seeing the dot).

Other suggestions?

You can't repair it. A dead pixel means that the transistor responsible for that particular crystal is shot. Therefore, the crystal remains in its state - forever.

What's meant on the site you linked to is something different: LCDs can suffer of a so-called "Memory Effect". Means, if a pixel remains in its state for a very long time, it turns sluggish and hence the picture that was displayed at that time appears to be "burnt-in". By actively trying to change the crystal's state you get it back to normal.
But the Memory Effect doesn't occur that easily. Otherwise, many LCDs would probably have the Windows taskbar "burnt in".

In your case, you can't do anything about it, as the transistor is broken. But some vendors or manufacturers have a zero-dead-pixel policy. Check if it applies to you, as if it does you can have it replaced.
Otherwise, you have to live with it. But you'll get used to it, as 1 subpixel is not that noticeable (my old TFT had 1 red subpixel and I got used to it).

If it is a stuck pixel, and not a dead one, you can run a certain .gif file fullscreen for a couple hours to unstick it. I cant be bothered to find it right now, but I think it just flashes primary colors at a certain rate that magically unsticks stuck pixels.

It sounds like the file I was referred to by Viewsonic at:

I ran this for a couple of hours and it did not make a difference.

Is there a way to distinguish a DEAD vs STUCK pixel?

Unless I'm mistaken, a dead pixel will be completely black and a stuck pixel will remain a certain color.

Dead pixel = traffice light that doesn't get any power. Stuck pixel = traffic light that can only turn on one color. Got it?

I'd call up their customer service and see how they could help. I'm the kind of person who will not accept under any circumstances even one busted pixel. For several hundred dollars, any monitor I buy had better be flawess out of the box. Yes, busted pixels in some displays are an unavoidable aspect of the production process, but I won't have any of that. You might be able to ship the monitor back for *relatively* cheaply and then purchase something similar from a local vendor (circuit city/staples, etc).

J&R Music gave me an RMA #. I plan to return it this weekend. Has anyone ever fixed a pixel problem running one of these on-line tools? It is hard to beleive they would work.

Returned the monitor J&R replaced it. I carried it back to their store in New York. There was another guy with the same problem (mine was Viewsonic his was Sony). They replaced his also.

They did tell me that the manufacturer states a couple of "dead" pixels are "normal", but J&R didn't give me a hard time about the return.

I would recommend them for future purchases. They also were able to price match and had it in stock.
