OK, I'm going to assume you've checked the monitor. If you haven't -- do
so. :-) (Different board on the monitor, or this board on a different
monitor. Or -- hook up a scope).

I say that ? The lines I see are curved and fuzzy. Digital problems usually
show up as fully formed vectors in the wrong places. It also looks like it's
drawing on the side of the tube, which again to me indicates analog.
At the risk of sounding repetative :-) Start at the test points with a
scoope and work back until you find a good signal.
Checking all voltages, as someone suggested, is also a good first step.
Hmm, sounds like the makeing of a FAQ -- where to start with DVG/AVG
problems.
