No light on screen - screen broken?

[JC_Derby]

had my zen for a few years now and all of a sudden the screen has stopped working. The Zen connects to my pc just fine and appears to play.
But the screen isnt getting anything on it.

does that mean the screen has broken or the backlighting?
Im not sure whether i can post a link or not - but if it is the screen that is broken is this one
