Seriously, I tested it by bending a paper clip and using that to short out
the suspect fuse - lo and behold, the screen lit up! If the fuse is ok, the
paper clip will make no difference, but of course you don't want to short
the fuse to anything else :)

Heh - I'm still looking for stuff a couple of months after moving...and
