White screen

My monitor has suddenly gone to a completely white screen. It will not even allow the on-screen controls to display. I've already connected it to my other computer and even used the other computer's power and data cables to make sure that it was not those either.

My bet is the monitor is dead, but I'd like someone else's input to be sure before I go out and get a new monitor.

Thanks in advance, all you Fixya folks <G>
