all functions OK except for auto-dimmer

However, still having issues with both screens flickering/not working
under on "HIGH" state of any input.  I think this may be a hardware
issue.  Perhaps a lack of shielding or loose wires.
Auto-dimming is working (mostly)

Autodim feature has been re-worked to function correctly.
Unfortunately, the displays are still showing nonsense when exposed to
too much light or other switches on.

Also, after some time it seems clock loses first digits and just
displays the trailing 1-2.
