I got 75 on the R, G, and B signal pins. Without a schematic, I
wondered if the sync pin was fed by a transformer, in which case zero
ohms could have been correct.

When I checked the monitor pins, a scope showed several problems. A
local drugstore chain has refurbished computers and monitors similar to
theirs for $250. Why fix it?


Personally I'd give it a shot just because I can, but you're right in that
it's not worth spending a great deal of time or money on it.
