Haha... my brother did this to my TV a couple years ago... the colour shift at least for me goes back after a couple of days... so I would just wait a while... for me I just had to keep the 15" speakers at least a foot away from the side.
We are talking about a tube TV right?
Yeah. We just decided to not keep it. The only way we could place it without magnetic interference was in the center of our living room, and that's obviously stupid. It was pretty frustrating, though.
