Organisation can make TV better! (5)
I believe the answer is:
setup
'organisation' is the definition.
(I've seen this before)
'tv better' is the wordplay.
'tv' becomes 'set' (a television set).
'better' becomes 'up' (I can't explain this - if you can you should give a lot more credence to this answer).
'set'+'up'='SETUP'
'can make' is the link.
Can you help me to learn more?
(Other definitions for setup that I've seen before include "Organisation (informal)" , "Fix" .)
