Hi can any one help me?, I have a toshiba satellite 1800 and my screen goes black every now and then, the computer is only 4 yrs old. When it goes black i can just see a picture and i can see it better if i shine a light on the screen. Now when this happens, I turn it off, then on again,and sometimes when i turn it on its black and other times its ok and will last for days! so I am confused, is it my screen, or backlight, or what?!! If anyone can help me it would be great, the computer is out of warranty, and ive heard that sometimes its cheaper to get a new laptop than get a new screen, I hope not! cheers to all!
