Repin the headers to the opto board. Use molex instead of IDC.
@David retro stocks the header crimps and I think the crimper?

Thats one of my next moves. Ordered parts and crimper from Pinball Haus here in Aus. Also gonna measure the 12v once the games been on a while. Seems to be when it starts happening.
You need to get the connector replaced first. You did say that it was a new opto board, however, if the opto board is an original 30 year old board then the electrolytic capacitor has more than likely leaked and will need replacement with possible pcb track repair work.

Unregulated 12v on the power driver is giving me 12.1v however pins 1 on J2 and J4 are reading 11.6v. Im assuming thats where i measure the voltage coming in? seems a little low

Yes i know im waiting for the parts and then ill swap it over. Then at least ill be able to rule out that connector. The opto board is not an original, its an aftermarket remake.

J205 pin 1 is also only getting 11.7v on startup. I think this is where the opto board connects to the cpu.
