Take the edge connector off, but leave the side molexes on, and try again. I've seen board issues that only screw up the picture when the edge connector is on, but take it off and you get a perfect picture (even though you can't play)...
 
no, it didnt work in the cab before I jammatized it. Same pic/issue. Harness works though, I had a multi (locked to only play galaga) but now I want to get the original board back in the game
 
What he means is, are you sure the problem isn't with the adapter? Your adapter has the two molexes that go out to the side connectors on the Galaga board, right?
 
I have had similar issues with that adapter... Try wiggling the video molex connector... Does it change the pic ?
 
If all the voltages don't jive, then you might want to start with the Galaga Renewal Kit that "channelmanic" has posted for sale in this section...it includes new resistor packs and IC sockets that are troublesome for Galaga
 
Unless you have good repair skills, you need to have a known working boardset to swap parts to isolate the problem area.

The problem with Galaga is that the custom chip legs rot and are pretty likely to break or crumble to pieces as you swap them! :-(

If you want the end result (a working boardset) send them out for repair.

If you are interested in learning the troubleshooting/repair skills let us know.
