turn up/down tv volume

[Untaught88]

Hi,

Is "Turn up/down the TV volume" correct?

Yes. Note that you omitted the definite article in your title although you remembered to include it in the post. You also failed to capitalise "TV" in the title but did it correctly in the post. Please take more care.

Note that you don't have to include the word 'volume'. It's not wrong to do so, but it's superfluous. It's understood and maybe even more natural without it.
