Hey everyone!
So I am still working on a ghostbuster Pro that had a bunch of issues light related.
All the non working lights and flashers were all on the same circuit which went back to the node8D board on the bottom left of the under playfield. So after checking all the bulbs and checking the power on the board and seeing that everything was right I thought that the logic part of the board must be dead and so I ordered a new one. But after install, the same lights are still not working.
I found this post and followed the instructions but still no luck.

The guy ended up changing the board anyway and that didn't help me.
I checked the cn1 cable that runs the data from another light pcb and it does seem to connect. Only the MISO pin does not trace from cn2 to cn1 but looking at the board this seems fine.
Any ideas?
