This is most likely to be caused by the screen backlight not working - you need to get the backlight or inverter replaced.

I don't think this problem is related to a virus, most likely this is a hardware relate issue. Here are some troubleshooting tips. Test your laptop with an external monitor attached to the VGA port. If the external video is working fine then most likely there is nothing wrong with the motherboard or video card and the problem is somewhere inside the laptop display panel. Most likely you have a bad LCD screen. I doubt that this problem is related to the video cable because when you have a bad video cable it affects video on the whole screen, not just on the part of the screen. I guess you'll have to replace the laptop screen.
I don't have a precise answer to your problem but the same thing keeps happening to mine. I think it is a bad connection from the computer to the screen (it happens when i bend the screen back) Everytime it happens to me, I either shake the laptop, hit the screen until it stops, or bend the screen back and forth.
my laptop is turned on but my screen won't work.
Either via remote desktop connection or by attaching a external monitor. If your laptop screen does not show anything - not even a manufacturers/Microsoft logo during start, it is likely your screen is broken. If your laptop-screen shows a very faint picture, it is likely the back light of your laptop screen is broken / disconnected. If however, everything is normal, up to when you would normally see your lo gin screen, but then your screen goes black, it is likely to be a setting on your computer, which you yourself can fix. Please refer to the related link black screen. If you get a new laptop and bring your old laptop to the store you can get the info transferred from the old one to the new one you can also do this with cell phones. Ken Eddy

I have had the same problem myself, could be the ribbon cables loose to the screen or could be something else, first thing I would do is reload the machine 2 or 4 times, that would steer you in the right way,if it did not cure the problem you would know the screen is the problem.
