A ferrite core on its own probsbly wouldn't do much (unless it was
inserted inside a coil, say). It could be associated with a permanent
magnet, though.

Another possibility is that there's something else -- say a permanent
magnet -- missing. Conpare the top and bottom of the yoke and if anything
is not theee. A permanent magnet, of course, might be stuck to any part
of the monitor chassis (and might be messing up the raster as a result!).
