- I'm wondering where the snowy screen information comes from, on a TV
- set that isn't receiving any real RF video signal.
-
- Is the snow "in the air" or does it only exist in the TV's tuner?
-
- If it's noise from earth and the rest of our universe, will this
- messy information fade away if I hide the tuner's receiving parts
- behind a shield that's good enough?
-
- I don't need the answer to solve a specific problem, I'm just
- curious about how these things work.
