i know not really electronic repair but i could find no other
suitable group.
I have two big color spots/circles (3" diameter) on the
TV/CRT
with a big bright stripe between the two spots put there by a
3/4" x 3/4" cylinder (? hematite ? it is strong ?) type
magnet,
the cylinder version of these
http://www.kjmagnetics.com/proddetail.asp?prod=MT%2DM
is there a best way to repair ? how ?
Google for "CRT degaussing".
If you're lucky, proper application of a degaussing coil will
remove
the residual magnetization which has been left in the CRT's
shadow
mask/lines by the small magnets, and will restore proper color
on the
screen.
If you are *un*lucky, the little magnets are so strong that
they
actually attracted and bent the shadow mask/wires when they
were held
up to the front of the CRT. If this has happened, degaussing
probably
won't eliminate the discoloration - I don't know of a remedy
other
than replacing the CRT itself.

Thanks Dave,
That seems to be what possibly happened. The degausing part
seemed to help some of the problem but the rest was remedied (?
perhaps luckily ?) by waving the original magnet diagonally
across the screen and problem area.
Thanks again.
