Home - Consumer Electronics - TVs - Resolved Question
It happens only when you switch the lights off. Go and check again. Lenz's law and the conservation of energy says the current cannot stop instantaneously when switching off the light (breaking the switch). The result is a build up of charge and consequent electron discharge over the air gap which produces a very short emf spike which disrupts the tv.
Erm...doenst happen at my home. Maybe its time for a NEW TV? LOL
it has got to do with the electrical current running through the house....if there is a leakage somewhere it will affect the tv,radio etc.
Electro-magnetic fields are created when current changes. If the current is constant, no electromagnectic field. If they current varies (current "slowly" decreased as you switched of your lights- electromagnetic field, which also exist in your TV (how the electrongun creates the images), interfering with your TV.
Yep, electro-magnetic fields. We also have them. When I walk past my radio sometimes, it moves to a different station or the sound gets louder or softer. And my TV sometimes also does strange things when I move close or further away from it. Is that good or bad? Or maybe I'm an alien. That's a thought! How would I find out??
Seems there might be some small problem on the DB box in your home.
That doesnt happen to me. Maybe check out your connection.
