Hardware troubleshooting through process of elimination.
Unplug the video cable from the monitor and power it on. It should show "No signal detected" or something similar. This is basically the built in test on the monitor, if you see the a message the monitor is probably fine.

Unplug the power and remove the battery and hold the power button down for about 10 seconds. Plug the battery and power back in and test.

If you still get nothing let us know if this is a laptop or desktop to troubleshoot further.
