It then becomes inoperable as you can't press the buttons. And weather
proof boxes exposed to the weather have this bad habit of not quite
being as weather proof as you think and some how end up with water inside.

It's definitely the LCD - the liquid crystal has escaped it's matrix and
the display shows random blobs. In places you can see the original
indications and the back light comes on. It's had to say but I think the
rest of the electronics is still 100% functional.
As I don't think the unit ever suffered a mechanical hit, all I can
think is that this time it was heat related. It gets hot (and steamy)
under cover that goes over the boat between trips. We have had a
particularly hot summer this year.

The previous Expert Pro I had suffered corrosion (due to water getting
into the supposedly waterproof box). The corrosion was helped on it's
way by the DC power supply..
I and a tech at work did try to replace the corroded tracks, but it
never really worked properly again.
Actually I still have the carcass of that one some where, and it's LCD
was still functioning when the electronics died. A transplant may be in
order as I think the screens were the same between the original Expert
Pro and the later 'HV' model.
