A real head-scratcher

So we hop in the plane yesterday for the 50 minute flight to
Janesville, WI, and I notice that the display on our JPI EDM-700
engine analyzer looks funny.

Some of the LED numbers are missing pieces. Most are not. All the
vertical graph/bars appear to be fine.

Now for the odd part: The missing segments of the LEDs are NOT
consistent. For example, the same section of LEDs might improperly
display an "8" with a couple of missing segments on the right side of
the 8 -- but the next second it will change to a "9" and those right-
side segments will appear normally!

It's almost like the internal programming for the display of numerals
is screwed up, rather than the display itself?

Any theories here? I was hoping it would cure itself (ha!), but it
was the same on our flight today....
