Have you checked that the machine isn't in test mode ? In test mode there
would be a cross-hatch pattern on the screen, and I think start is lit. I
can't remember what the button test does, possibly you should hear tones
when you hit the buttons.

Any chance your have or can borrow a dual-channel o-scope with an XY mode ?
That's the easiest replacement for a vector monitor for testing.

I wouldn't power up that monitor until you are sure you have the board
working.
