Pixel blue on white screen

Hello guys, I am with this problem ..

When with my macbook realized on white backgrounds find a pixel that lights up blue.

On all the other colors do not seem to light up a different color, it only happens on a white background.

Sorry if my English / American is not as good as I would like, but I think we understand each other ..

How can I solve this problem?

- Replace the LCD panel?

- Replacement LCD Cable?

- Other?

I would not find myself to buy a lcd panel to no avail, since I want at least 1 year still hard for the mac then buy a new model.

Thanks to all.
