Going back even older, the first TV's didn't have degaussing coils built in. If you moved the TV, a technician would have to come to your house with a portable coil and do it for you.
- gist 11y agoWow what was the reason that moving the TV meant you needed to degauss? Obv. has to do with magnetic field but I always thought it simply had to do with power being turned on (and only because that is when it seemed to degauss).
- URSpider94 11y agoSimply that moving the TV exposes it to a different localized magnetic field -- just like a compass inside a building. This could also be the result of moving around big loudspeakers near the TV (especially if they aren't magnetically shielded). Built-in degaussing circuits fire when you turn on the TV presumably because (a) it disrupts the image, so best to do it at turn-on than randomly while you are watching, and (b) because you are unlikely to move the TV while it's on.
