I had the same problem on a brand new 32" panasonic out of the box and I called Panasonic and asked WTF was I going to have to take it back to get it degaussed and they said no, just turn it off and on a few times and it will go away. I thought that was BS untill I did it and it went away. This was light magnatisim I do not know if it would work if It was more severe.
