I have been working on a Xenon for a while now and decided that the board was too far gone to repair. I put an Alltek board in and it solved all of the issues I was having. However now the 7 digits scoring will only show 6. The final digit does not light up. Before on the other board it was fine. I went through the settings and could not locate the issue. The game plays perfect now except this issue. Any ideas?
