Leave the TV unplugged (3,3)
I believe the answer is:
set off
'leave' is the definition.
(set off can mean to depart)
'tv unplugged' is the wordplay.
'tv' becomes 'set' (television set).
'unplugged' becomes 'off' (I've seen this in another clue).
'set'+'off'='SET-OFF'
'the' is the link.
(Other definitions for set off that I've seen before include "Begin journey or cause to ignite" , "Commence journey or detonate" , "show to advantage" , "Counterbalance" , "Commence journey or explode bomb" .)
