I fixed a couple of _Space Duel_ boards recently that had a similar problem.
Turned out to be bad op-amps at the video output -- one of them caused an
axis to rail against the wall. Another one had a bad solder joint. I
forget the exact part number, but I think they're TL082 chips. They're
generic dual op-amp chips and are quite inexpensive. Try swapping them out
(they're in the video output section of the board) and see what that does
for you.
