I don´t have a lcd monitor yet but this might be useful to some of you who already own one. This is not supposed to be working for every flat screen out there but I think its nevertheless worth a try. Take a look at the following site and decide for yourself if you want to try this method.
You simply apply pressure to the dead pixel and remove it at a certain time. Sounds easy ? well try it out and tell me if it worked.

Sorry, this doesn’t work. You cannot fix a dead pixel.
Case in point: Dead pixels are different from Stuck pixels. I know beause I had used LCD monitors which had dead and stuck pixels.
Taken from the site you mentioned:
“These instructions will fix “stuck” pixels, not “dead” ones. Dead pixels appear black while stuck pixels can be one constant color like red, green or blue.”
i wonder if this will work on old laptop lcd screen..anyways, worth a try..
thanks..
