anyway to repair dead/stuck pixels on lcd??

[flyimages]

i have a tiny pin size red pixel on my lcd and was wondering if there was anything i could to to try to correct it???

I don't think so. I hope you're within the vendor's return policy time limit.

i found a couple of software/tips that may resolve the issue, i'll give it a try this evening.

I rubbed my screen with a soft cloth and it got rid of my stuck blue pixel.

Worth a shot.

You can try and massage the stuck ones but the dead ones I don't think there is really anything you can do.

is there anyway to distinguish a dead pixel or stuck pixel by just looking at it?

Not really...

I read somewhere that a dead pixel would appear black behind a white background where as a stuck pixel would be either invisible or appear as a different color.

Dead pixels on IPS/VA screens would probably appear black, but on TNs they would be white with no voltage being sent to them. Or, if there's a flood of voltage being sent to them (another *possible* defect), then it would be the other way around. And likewise with dead subpixels it's hard to tell...on a TN a dead red would make it an 'always on' red.

any luck OP?

I had the same problem (stuck pixel) and managed to fix it by massaging the area and running software such as 'dead pixel fixer'.

The 'software' is just a movie that constantly changes colours to try and activate the dead pixel. Just run it on a loop. Not guaranteed to work but worth a try. It worked for me.

A "stuck" pixel is the same as a dead pixel. An LCD pixel is a shutter or window with a reg, green or blue filter. When a pixel is always on, it just means the shutter is stuck in the open position, instead of the closed position. In either case, it is not responding to the electronic signal to change one way or the other.

I don't have any personal knowledge of why rubbing the area could fix it, except that doing so may create a local static charge that unsticks an individual pixel driver circuit, and I have no idea whether it would prevent the same circuit from going into the same lock up state, again under the same conditions.

A shutter? :laugh:

I fail to believe you did not understand his analogy.
