Damn.

Well I only noticed it yesterday. Happened after I moved the machine 
from one room to another. I was wondering if maybe it was just some 
moisture or something and it might go away after a while. Or maybe I 
just need to jiggle the display gently and it might work again.

But I guess not. :-S

Still, the oven still cooks food, so...
