Working on a Nascar for my friend. The lower two ball accelerators aren't working. When I run a track test, the display shows L2 missing.20220304_004819 (resized).jpg20220304_004819 (resized).jpg

Also we found this inside the cabinet and we aren't sure if its an extra or something that may have fallen off the playfield. Can anyone identify it?

Lastly, I'm missing what the manual shows is the display power supply board in the upper left corner of the backbox. Im assuming the display that is in it is an LED display and doesn't need it. But we can't figure out how to get the odd letter shadowing to go away. 20220304_004549 (resized).jpg20220304_004549 (resized).jpg

*Solved*

Found the solution to this problem. Turns out I had a column transistor out on the board. So all of the switches in that column were not registering. Replaced the associated transistor (Q5) and everything is working again.
