However, in recent months, one of the LED segments has begun to
misbehave. It is getting steadily worse. What happens is, in general the
segment is dim, and once a segment lights, it doesn't seem to turn back
off until you clear the calculation. As a result, very quickly, the one
segment just stays on 8.
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.
