Why are strange sounds coming through my tv?

Can't tell without actually hearing the sounds.

Sometimes the best anyone can do is guess their origin.

Look inside the speakers for baby grasshopper eggs?

The Russians are brain washing you just like HILLARY CLINTION claimed.

You are now under there control.. Now vote for TRUMP.

Because it is turned on.

they're heeeere....

Might be a bad signal or the sound board has a issue. Hard to say without having more info. If it is the tv it may or might not be worth fixing, depends on the value of the tv. If you end up needing one check this place called Best deal in town great deals on TVs http://bestdealdenver.com/

It's called brainwashing.

Aliens

My TV has been doing that too ever since Netflix added a hentai section to their streaming service.

Those sounds may or may not make more sense if you watch the accompanying video.

Is it when your tv is on? If yes then i guess there's a problem inside of your tv
