The problem was a defective Macbook 13'' screen. This issue happen just one month after the warranty expired. The screen in some times start to freeze and turn white.
The repair was more or less easy. The only think that was very difficult, was connect the panel to the very tiny and delicate connector on the computer. Also I don't have a heat gun so, I used a hair dryer to remove the boundary of the display.
Do this with time, and with the correct tools.
