Oh man... Look out for all of those loose hockey pucks flying every
direction on the freeways out there! And DON'T jay walk. Not because
you're very likely to get a ticket, but because CA drivers aren't used to
having jay walkers in the road and are famous for running them over. It's a
bit like being a manatee in Florida waterways.

Hmm... so was that blinking before the 70CT LCD went black an indication
that it wasn't the LCD that went south? That's interesting. When I put the
LCD from the 50CT into the 70CT, if it doesn't light up, that will confirm
the problem is a lamp or circuit ay?

Where is the exciter circuit? If it's on the MB, and IT'S bad, then
swapping the whole lid would be a lot easier, and maybe the 1st test I
should try.

Heh... still trolling for parts ay Neil? :-P

Yeah... I've got that set for a 30 minute auto off.
Still, don't know why the top half of the case is fighting me, or why taking
off that one screw seems to get the back right corner (looking at the unit's
keyboard/screen from the front) to begin to lift off. It's not listed in
the manual as a screw that needs removing.
