Sony Vayo All in one - VCG-JS210J

Screen turns black after a few seconds, even during the boot.
I can hear the fans and HD working, but no image on the screen.

I'm trying to reinstall the OS, but no luck.

I was able to reinstall the OS (win 7) , but monitor turns blank after 1 minute.

I can use a flashlight to see the screen, and every time I change the resolution goes back to normal for another minute and turns black again!
