I will make this short
I bought an lcd screen which has 2 dead pixels, seller said need to be more than 5 to replace new one.
People said laser can make lcd screen pixel go dead. I'm not sure this true but sound better than other suggestions i read on google.
Here where i need your help:
what laser do need? how much power in what wavelength?
as too much power will burn the surface of the screen or too little will not do the job
