screen after a magnet has been held against it(my 4 year old daughter)

if not the tv is a rental anyway so i will have to return it a play
dumb about the problem.
any help would be great
thanks

You can build a degausser. Wrap an iron rod with wire. Then run an ac
current through it and wave it over the magnatized area on the screen.

There should be no need to do this. The internal degausser should clear
it up in a few days or sooner.
