Quoted from Xantari:OK, i'll double check the connection. It's J2 plug on the 10-opto board it appears. I'm also ordering a 10 opto board and a 5 bank opto board as a precaution. I'm guessing if I replace both those boards there should be zero issues. Sort of the sledgehammer approach but i'm not able to repair boards myself.
How do you read the switch matrix on screen? I'm confused as to how you are supposed to interpret it (this is my first pinball machine!)
Replacing boards is a good start, but connectors usually end up being problems as well, especially at J206 on the MPU if there was Battery Acid Damage.
If you really want to eliminate issues, buy the Pindorabox IR boards, any others are just garbage. Also, if you are rmoving the MPF and tearing it down, I would replace the single optos on that unit as well. Taking that unit out is not easy and it is easy to bend the frame. Just my 2 cents. Good luck with this and keep us posted.
