[TenTec] Corsair - blank LED segments

[Steve Hunt]

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!

73,
Steve G3TXQ
