If I recall correctly reversing the cable gives all LED on. Since there isn’t power in the cable it isn’t that dangerous.
Ok so PP is always 0. That could explain why you have all LEDs off. What a out the clock signal at pin CC and the 74193 counters? Is there a clock and are the two 74193 counting correctly?
