Casio CZ/VZ Files... part of CZsynth

Hi there,
 
I'm the proud owner of a VZ-10M but have a screen problem, basically it was fine and in between the time I bought it and rackmounted it, this happened [see pic]. It wasnt hit or damaged by anything, just simply sat on a chair so I'm mystifed. Any suggestions or do I need a completely new screen, or maybe just a loose connection or something, though I doubt it. It;s still usable, as long as it doesnt spread northward.
 
Many thanks, keep up the good work and nice VZ sounds. 

Chris
