Hi Tim, 

The screen just goes black.  I've seen this before with LCD displays in
direct sunlight -- I think it's because the direct sun heats up the liquid
crystal.  Whatever the reason, once it happens there's no pulling up the
contrast button because it's invisible!

BTW, if anyone can explain the relevant aspects of liquid crystal technology
to me I'd be grateful.   It's something I've wanted to find out more about
for awhile, but never quite got to asking.
