I'm kind of at all loss here, I just bought this BSD from a fellow Pinsider, it had opto issues to begin with, however I checked the wiring and reseated the connectors and it started working. It was good for a few days and then the other night I turned on the game and almost instantly smelled something burning. After some poking around I saw that the 24 opto board was toasted (pics attached). I took the board off and measured the voltage coming in and it was 12V. So I can't understand what led to this board getting burned up.
I have a replacement Homepin board and I installed it but the long range optos are not registering. I tested the optos with the remote control and it did not register. Also, the left side opto which I believe is the receiver beeps on the switch test when I put a ball in the left gate, but I get nothing on the right side. I swapped the white opto with the one from my FH (since it's torn down) and still can't get the opto to register. Any help would appreciated.

Thanks pinballdoctor, I tried that and I got the optos to show on the screen. However, it's not conclusive, after testing a few times while shaking the different wires around the Homepin board stopped registering or the green light would come on very faintly.
