Looks like a LED board failed early in the chain. W6 to #29 to # 1 to #2 etc. Find the first one out after the last working one, the first one out failed.
Page C-54 in the manual shows how data harnesses run. If the data harness reaches, you can by pass the failed LED board to get the rest going, then go into Settings - scroll down and turn the by passed board off. Be sure and turn it back on when you put a new LED board in.
If the game is under warranty, you can open a ticket on the support desk to get a new one. If not, the store on their website sells them.
