Notebook monitor after going through airport x-ray became red

Hi. I have such a problem. The notebook went through x-ray scan in the airport and after that I've turned it on and noticed that the screen appears to have more reds than any other colors. So I can still see blue and green actualy but white color is now seen as slightly pale red. That pisses me off very much and also my eyes now are in pain watching too long into the screen. What should I do?
