    Usually if you turn it off, let it cool for a half hour or so then turn it
    on again the internal degaussing coil will take care of things. You may have
    to repeat it a few times to get it all the way back to normal. If that
    doesn't work you'll need to borrow a manual degaussing coil or improvise
    with a bulk tape eraser or Weller soldering gun.

    Use an AC powered tape ( like cassette or VHS ) eraser.

    averagebrian,

    You may also try using the magnets to "rub" the color off of the
    screen. Starting from the center of the affected area, hold the magnet
    near the screen and move the magnet towards the edge of the screen.
    Repeat as necessary.

  5. Hi!

    You simply need to degauss the TV set. For many sets simply leaving it off
    for a while and turning it back on will do the trick. Other sets may need to
    be unplugged for a long period of time (overnight) in order to degauss
    themselves.

    If that doesn't do the trick, multiple cycles may be needed to clear up the
    trouble. Failing that, use of an external degaussing coil (such as a tape
    eraser, or the proper tool) might be needed.

    There also exists the distant possibility that the magnets were strong
    enough to deform parts inside the picture tube. This is very unlikely
    though...especially with most common magnets.

    See the group's FAQ at (mirror) http://greyghost.dyndns.org/repairfaq/ for
    more information.

    Turn the set off for more than about 30 minutes. When it re-starts, the
    internal degaussing coil should degauss the mask in the CRT. It may not do
    the total job the first time. You can watch the set the way it is, even
    though it is a bit annoying. Eventually after the set's power is recycled
    over a period of days, the degaussing coil should eventually demagnetize the
    screen. If not, then there is a problem with the degaussing coil circuit, or
    the coil itself in the set, or the mask in the CR has been damaged.

    Normally a magnet will not permanently damage a CRT, unless it is extremely
    strong. It is not good practice to put magnets near to a CRT mask.

    Do not try to demagnetize the screen by seeing if you can neutralize it with
    magnets. This is not a good practice.

    If you are in a hurry to degauss the screen, you can call in your local TV
    service shop to degauss it manually with a hand held degaussing coil. You
    can also buy a hand held degassing coil from most of the major electronics
    parts distributors who specialize in parts for servicing TV sets. This item
    can cost about $80 to $120 US depending on the manufacture and model type.

    Had a set where an iron screen had been removed from around the
    power supply and flyback. That certainly didn't help picture, quite
    a rainbow effect.

    Do nothing. The TV will correct itself - may take a few days, but it's best
    left alone. It won't get worse if it's left alone (unless your daughter
    plays with magnets again)!
