Got an Asteroids Deluxe in the workshop I'm very slowly working on. When it arrived, it was stone dead.

After fixing the power supply, the board made sad ram noises and ended up needing a few RAM chips replaced, and then it was playing blind just fine, so I thought all was well in the world.

However, after I fixed the monitor (powered here by Arcade Jason's Vector TPG by the way, which is awesome) I noted that there was actually zero deflection coming out of that board at all, on X or Y.

Didn't have much luck searching forums, as all the hits for "Asteroids Deluxe Playing Blind" yield either monitor problems or purposefully disabling the VG. It's not the voltage regulators on the output either, and the board seems to be properly getting the 36VAC, so I'm not sure off the top of my head what's happening here.

Any pro-tips would be appreciated, otherwise I'll update when I figure it out.
