Is there any way to test if a Vs. board it working? (Besides plugging it in to the cab). I need to figure out if it is the thing that isn't working in my cab, or if it's the main board/harness/etc.
 
You need a known working setup to test it with. That could be a working cabinet or a workbench setup.

Alternatively, if all the roms/rams/cpu test good, there's a good chance the board is good. If you're looking for a way to look at a board and have it tell you if it's good or not... sorry.

EDIT: Also, if you have an oscilloscope, you could probe the video outputs to see if it's doing anything. Use a multimeter to check power supply voltages first.

do you have a different ppu to try out? i had one ppu that was bad and all i got was a screen like that.
 
I use a Nintendo to Jamma adapter and then build a second adapter that goes from Nintendo to Vs. If you've built Jamma adapters before it isn't too difficult, but does take some work. The Nintendo to Jamma board inverts the video signal and amplifies sound for you.
