Step one was to plug it in and see what happens.  The monitor originally had vertical collapse.  After determining that, I did a cap kit. 

 

After doing the cap kit, the picture was still better, but still only took up 1/3 of the screen vertically.   I then pulled the XY board from another 4600 and swapped them.  This allowed me to narrow it down to that card.

 

After that, I followed the 4600 flow chart and started replacing the transistors on the XY card.  The picture then filled the screen, but had Sync issues.

 

Turns out the sync issues were because I was using my JAMMA rig to test the monitor.  I then decided to just hook it up to my Make Trax (which also has a 4600) in it, and I got a perfect picture after that.

 

Since I got a perfect picture with the Make Trax, I was able to determine that it was in fact my JAMMA rig being hooked up incorrectly.  Once I fixed that, all was good.
