Display problems with Vaio cr-21z

[Doctor_Pino]

Hi.
Today I have seen that the display of my Vaio has an orrible problem!! When I open Msn messenger or I open a mail, the display has some instant of failure (the display turn off for some instant..it is like a moment of low voltage).
I'm very tired, because the computer got only 4 months and this is not a problem that I can accept buying a Vaio.
If someone had the same problem or know what I can do I say thank to him anticipately.
Thank you all

Hi,

The whole display turns off in other SW also?
After how much time display turns off?

No, it turns off only with Msn messenger, for a very little instant, in which there is not properly a turn off but something like a vibration of the screen(the image goes away and return on the screen several time in an instant)
