I will check again at home (@ work now) but I'm 80% sure I do get something similar.

make sure the jamma connector is on the correct way round

Not sure what you mean? As far as I can see there's just one way it can possibly be on.
I checked the voltages again, it was a bit high but I got it down to 5.05, still nothing though. I keep hoping there's just something stupid I'm forgetting here.
If SF really doesn't need -5v then I am at a complete loss.

got a photo of the jamma connected to the pcb?
unless your jamma has a key way its very easy to plug in the wrong way round
very few game boards require -5,some need -5 for sound and some others used it for graphics
maybe we are looking at the wrong thing,try turning up the brightness/screen volts a little to see if you get anything on screen

Here's a somewhat blurry one I took before I knew I could slide it out in the open. I can take better ones tonight.
It looks to be exactly like this:

Something strange is the 2nd ground up isn't labeled as anything, just the first.
