Just Why ??
Why some times a segment display is missing and only in specific numbers. For example... #0 use the same segments as #8 and its missing the left upper segment from all numbers in the same display card
When I run controller test as "turn on all"... All segments light up correctly.
I changed cable, tested 3 differences display card and even connect in a 2 different master card .
It its powered by 5V PC supply.

Please how to fix this ?
