    It'd be nice to know which Mac you're having this problem on.

    Was it on sleep for a long time?
    Was the battery charged?

    1. Reset PMU. Don't know exactly the procedure for your machine, but this is where I got help when the same thing happened to me. (http://docs.info.apple.com/article.html?artnum=14449). Actually, what I do now is just turn off the machine, disconnect the power, yank out the battery, wait 5 sec. or so, and then put back battery, reconnect to AC, and restart.
    2. Restart from the original Install/Restore disc that came with your Mac by inserting the disc and start up holding the C key down until it starts. If the display works, then you have a software problem. Do an Archive and Install.
    4. See if you can hook up to an external display. If the system shows up on that display, then you know it's your display.
    3. If it's the display, you may have to get Apple techie support.
