From what I can gather from that. Does BIOS boot up or not? I would bet a bad CPU, I had one go out a few months ago that did that exact same thing.

It sounds like a damaged monitor, what I would do is plug an external monitor into the VGA port and see if it works from there. if so, look for a loose connection in/around the hinge for the monitor.
They are not very easy to fix though if that is the problem, you will probably have to take it in.
