Television vet (6)
I believe the answer is:
screen
I believe this clue is a double definition.
'television' is the first definition.
(thesaurus)
'vet' is the second definition.
(thesaurus)
(Other definitions for screen that I've seen before include "A film is projected onto it" , "Censer (anag.)" , "Standing partition" , "Room divider" , "show on TV" .)
