    I did that to my parents' TV once. When I noticed that the effect was
    permanent, I fixed it by waving the magnet in front of the TV with the
    poles reversed. It took some concentration, because reversing the
    poles makes the distortion look worse when you're fixing it.

    Are there any plans to put solar observatories at the Sun-earth
    Lagrange points, or in a tag-team orbit with the Earth around the sun?
    It would be nice to observe the whole sun, not just the portion that
    happens to be pointing towards us.

    Interesting article. My 50cm TV shows pinkish hues at the edge of the
    screen when it is rotated in some directions. There seems no degaussing
    provisions built in. (Set is 2 years old). However a fridge magnet stuck at
    a trial-and-error determined position on the exterior surface of the set
    just behind the screen where the pink spot is located neutralizes it
    nicely. No deliterious effects on colour purity after a two years.

    An experiment wich is simple to perform, is just to turn your monitor or tv
    up-side down. I have seen it done, and the result is practically the same as
    when
    you play with magnets. The image gets distorted with very nice rainbow
    colours,
    simply beacause of the earths magnetic field. I do not know if it happens to
    all
    tv sets, but if you have an old one just standing around, it might be worth
    a try...

    The effect may be real, but the cause may not be the Earth's magnetic field.
    To determine this, take your monitor out into a vacant lot away from local
    power sources or local concentrations of metal (it will require a generator or
    a long electrical cord), and then do the rotation. Again, I don't see any
    such effect with either my 27 inch CRT TV, my 19 inch computer monitor, or my
    13 inch color set. Its local fields from magnets in motors or DC currents in
    lines which may make the difference.


    Well, again, the article says something which might not be the full effect.
    Again, I don't see much of a change in the performance of my monitor when I
    move it from place to place or rotate it.

    when I
    Your monitor may be a high quality model that detects the local field and
    compensates for it, such circuitry is included in more up-market equipment.
    Anyway, I think we have flogged this one to death so...clear skies to you

    My magnetic compass is largely dominated by the earth's magnetic field
    and not the local power lines. Why should you be surprised that it is
    the same for a computer monitor?

    Very little of the thread remained. What effect was the poster looking to
    describe between magnetic fields and his monitor? Something about rotating
    it 90°...

    I am *not* surprised. The key point in all this is that for most monitors,
    the Earth's magnetic field should have a minimal impact on the image quality.
