Barry,
When you say "all four" digits, I presume you mean the 100kHz, 10kHz,
1kHz and 100Hz digit positions? They are driven by a multiplex
arrangement where the same segment in all digit positions is fed by the
same signal line. I would look for poor contacts as the most likely problem.
The 10MHz and 1MHz positions are also multiplexed, but separately from
the other positions. I presume not all 6 positions are showing the same
segment error? If they are, it's a very odd fault!

I've never mucked around with the LED freq display before but the
lower left vertical segment is out on ALL four digits of a Corsair LED
frequency display. In other words, "6" looks like "5" and "8" looks
like "9". Do they share something in common that would point to the
source of the trouble? Obvious things to check?
Thanks& 73,
