What could i do to cause a television to lose its image? some sort of wave interference...?

Question

like if i was to play a prank..i saw it in a tv series where the guy did something so that the tv started showing "fuzzy"..like if it losing its image.... thanks ..like if you are losing the channel...thanks

Answer 1

You could create a small oscillator. Or just make some kind of a spark box that radiates static all over the RF spectrum.

But if you get caught, I don't know you.

Answer 2

the only way to really make a TV go fuzzy would be to broadcast something at the same frequency at the TV is recieving, very awkward. If its to pull a prank i would recommend buying an all-in-1 remote and turn the tv off with the new remote subtly without anyone knowing that you've got it.  

Answer 3

invite mr. bean over

Answer 4

As they said, basically the easiest way, as you asked, is to interrupt the signal at the antenna.

Just to add to what AlfonsoX said: You don't actually need the same frequency.  As the front end, the TV "radio" receiver has a finite dynamic range, if it gets a big signal on a vaguely near-by frequency, it will suffer from one signal swamping the other. The result is however similar: you need a big signal & transmitting a big signal will annoy others & maybe get you visitors.

Much easier to play hidden remote games.

Answer 5

You want the TV-B-Gone. This was the scourage of CES 2008. Linkage below....

Answer 6

just unplug the cable

Answer 7

You can buy an attenuator from a TV store that reduces the signal on the antenna line.
