TECH : Asteroids problem

hi all.

i have a problem with an asteroids board that i havn't seen before, picture

that is supposed to be the test mode...

the game plays fine, but nothing intelligable is displayed :) its most
definately not the monitor, as this is running on a vectrex, it looks
identical in a cab, and i know both the monitors are working fine with good
boards...

does anybody have any pointers?

i was thinking maybe it was one of the dacs?

if you could help, i'd appreciate it :)
