Help, I was actually working on my computer (XPS m1210 connected to the 2407wfp) and the  monitory made a noise that sort of sounded like a sigh or perhaps air escaping something and the entire monitor went dead.  That includes the lights on the front of it as well.  Pushing the power switch (not broken) does nothing and changing power cords doesn't help.

Any ideas as to what is going on?  I see posts about inverters going out and lots of broken power switches.  I sure need it operating as a 12 inch laptop screen doesn't cut it for everyday work.

Thanks!
