In early days of color television it was recommended that the
final alignment of the electron beams be performed after the
set was installed due to the influence of the Earth's
magnetic field has on the convergence of the beam's and
the resulting poor alignment of the three colors as
seen on the screen. Better sets had Mu-Metal shields to
reduce the effects of stray magnetic fields. I have noticed
that the convergence of some of my sets seem to get better
and worse as their postion is changed. But whether this
is due to stray magnetic fields or getting bounced around
is anyone's guess.  But I don't see how just
being in the Southern Hemisphere would make any difference.

One side note. The famous compass maker, Brunton, used
to require that you tell them whether their top of the
line model was to be used in the Northern or Southern
Hemisphere. Later on it was announced that the "new and
improved" model could be used in both hemispheres with
equal accuracy. As far as I know there where no apparent
differences in the Southern model and the Northern model.

Hope this trivia sheds some light on the question.
