So I recently picked up a Gottlieb Diamond Lady from someone who couldn't get it working. I did all the ground mods and board mods, put in a new power board, cleaned connectors and nothing....no display...no solenoids kicking on....nothing. What's odd is that when the power to the display is plugged in, I'm less likely to get a blinking light on the one board. Anyone got ideas? I'm willing to try anything before I go ahead and order new boards.

Wooo...I took an existing mpu from my gold wings and swapped the roms out. Game is booting now. Still having issues with the sound but i'm getting closer. Anyone else have this game who's had sound issues? Thanks.

I think the best thing for me to try at this point is replacing the eproms. Does anyone here have the capacity to burn some? Thanks.

I had 2 system 80B mpus go down just recently in good working games same sorta thing just plain dead. Both quit while sitting in attract mode. One was a bad U4 RIOT the other was a bad U6 RIOT I already had them socketed to they were easy to test and swap out. Could also be bad connections on the daughter card. If they are suspect I typically just buy new daughter cards from Fred since the originals are easy to damage with only having single sided traces.
Sound issues depend on whats wrong. Are you missing all sound just some sounds or are they just distorted and glitchy? The most common thing I have found is bad op amps on these sound boards. Rams are not socketed so they are not easy to test. I doubt it would be a bad rom but anything is possible.

Earlier today when I first put my goldwings MPU in I still had a blinking light on the sound board and I was getting voices/sound effects and a weird garble...for music. I took out the sound board...reseated the roms, reflowed some new solder on the head pins to the connectors and now I don't have a light but the sounds and voices are very clear.

Problem is there isn't really a quick simple one size fits all method to fixing these 80B machines. All seem to have the same issues and there is really no better method than to go through the whole machine all the boards and all connections little by little. You seem to be on the right track.

Well the biggest obstacle is that I barely know what I'm doing. lol. I guess I could repin the connectors that go to the board. It would be easier if I had a way to test the board elsewhere. My goldwings has flat connectors where DiamondLady has pins.
