well having just recently degaussed a TV given to me by a mate, i have extensively researched the subject of magnetic fields. it seems some tubes are more sensitive than others. my particular TV didn't like being moved just 15 mile further south from where it ha been sat for 7 years. cant remember where i read it, but it said most of the tvs made in Asia for the northern hemisphere are sent with the tubes upside down as they are calibrated in the south. its also the reason some of the crt monitors come with a degauss button.
is that Mr Jacksons bubbles when he was a baby?
