Quoted from Crash:The pin layout on the board near the connector is not the same. I'm sorry I guess I was under the impression there would be no difference in designs.
This! After disassembling the board I finally noticed this tiny jumper that says signal enhancer bypassed when closed. Removed this and got signs of life! But what text that showed on the DMD during attract mode was frozen and the display became unresponsive, even after turning the game off. Now I can't even get it to display the game dots again but the behavior of the LEDs was different in both cases:

However, I did find the chip you mentioned and will try your suggestion next.
Hello together!
1st: at all: why is nobody talking to me from Lucky1 or Rappelbox? both have my Phone Number or E-Mail Adress?
2nd: the design problem was with the missed 3Volts for the buttons
3rd: the 2nd picture form Rappelbox post in Post #652 is my JUMPER bridge! And when that jumper (or wire bridge) is closed, means that the signal enhancer (74LS123N) is bypassed (look into the 2nd attached picture).
4th: my fault and it is also on the new orderd shields, I missed the HIGH Signal (5V DC) on Pin3 (CLR) from the 74LS123N chip.
Over all:
Sorry guys, it was my fault.
The solutions is easy, solder a wire bridge from Pin16 to Pin3 or put a small wire in both sides stranded and put the 74LS123N back in place.
1st picture the solutions
2nd picture the schematic with the missing 5V line.
Now I hope that everybody understand what the problem is and how the circuit is connected.
