Lcd problems f3jc

Hi all. I notice a big problem in some asus lcd notebooks. In this case, an asus f3jc with almost 3/4 months.
The lcd comes with a black spot, a very strange spot. Not a dead pixel, or a stuck pixel whatever. Very strange.
2 weaks ago, a white spot appears....
A strange white stripe appears...
A very strange defect in the lcd.

The spot...

The white stripe.

And again...

Notice that the white stripe only is notice in a black background. But is very annoying in these cases. (like windows or linux boot)

I have notice that a my friend notebook (a6j), has a bigger problem. The lcd have allot of big spots, really big spots belive me, like u have your fingers always pressing the lcd.... In the beginning it was little spots , but with time became enormous.
In this case I think it was bad usage of the notebook, but in the f3jc case wasn't.

Conclusion, this is very strange... I've already talk with asus support, and the answer was yes, they will replace it. The question is, what the f*** is these things?

Ps: Asus is great, don't be affect with this exceptional cases. Some times the lcds have defects... s*** happens....
