So the saga continues.
I received a large box from pinball bros and it contained:
1. Replacement I/O Board
2. New right side coil power harness
3. USB, HDMI and power harness that goes from the backbox to the I/O board
4. a Box with all coils and magnets to replace the entire right side
5. All new white PCBs for mounting underneath the machine
I decided to take a phased approach because holy shit that's a lot of work on a new machine to replace all of that.
I started by installing the new I/O board provided and then just unplugged the right side coil power harness just to remove the possibility of a short.
Of course the new I/O board will not detect in my game. The old I/O board with the bad right side was booting up fine and that's what I had removed.
I then installed the new USB, HDMI and power harness from the backbox to the I/O board. I used my meter and checked continuity and labeled all the connections to make sure they were all plugged in correctly and the damn thing still doesn't recognize in my game.
I updated my code to 2.6 thinking maybe the I/O board is like a node board and it might have to have some matching firmware to work. That didn't do anything except the machine is now updated to the latest code
I updated my ticket back to PB to see what the next steps are. They told me this I/O board was burned in for 16 hours before they sent it to me.
I really don't like this shotgun approach to fixing this thing.
