Are you sure it's a LED display? That sounds more
like behavior I would
expect of a vacuum fluorescent display. If an LED really is doing that,
the problem is with the electronics, not the diplay.
I can't be sure. I didn't think it was an LED (the unit is from around
1970 or so), but when I looked at it a little while ago, it looked kind
of like LED segments behind the plastic lens.
They glow a bluish green if that is any help. They don't look like any
LED out today, that's for sure. I've never knowingly seen a vacuum
fluorescent display, so I can't compare.
If this is one, is it a problem that is fixable?
