Sounds like your screen went bad.
Close the lid, attach an external monitor, open lid and see if the screen appears on the monitor.
Resetting the PRAM may do the trick also:
You reset the PRAM by rebooting a Mac and then immediately hold down the Command+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won't work.
Happy New Year,
