Blank Screen

Be sure that the power cable and the video cable are plugged into your monitor, the power cable is plugged into a good outlet, and the video cable is plugged into your computer. It's possible that you simply have a loose cable.

If everything is installed correctly, and if the screen is completely blank (no "cable disconnected" or "test mode" messages), then it sounds like your monitor is simply dead. Since there was a heavy wind storm recently, it was probably hit by a power surge. If you don't already, I recommend that you use a surge protector for all digital equipment.
