Well, I can imagine that with this kind of board you don't want to remove/replace those unless proven necessary to do so. What I would probably do first in such situation is that I'd check if I could make the lines "open" f. e. by removing socketed ICs or so and measure all of the lines, checking for noticeable differences in capacity/resistance among them. -- SD!
