Try hooking it up to an external monitor to see if you get video out that way. Otherwise, it could be that you need a new backlight or new lcd. Worst case, your graphics chip on the motherboard may be fried, in which case you need a new motherboard or new laptop.

I had this issue, and was unable to get video after hooking it up to an external monitor. I took it into a computer repair shop, and they found a large amount of apple juice inside. I could have found that myself if I wasn't so daunted by opening one of these machines up.

If your Lenovo IdeaPad shows a black screen on startup before reaching the desktop, see the Lenovo IdeaPad U530 Touch Shows Black Screen on Startup problem page for possible causes and solutions.
