Record collection not working (3,4)
I believe the answer is:
set down
'record' is the definition.
(I've seen this before)
'collection not working' is the wordplay.
'collection' becomes 'set' (set is a kind of collection).
'not working' becomes 'down' (down can mean broken or not working).
'set'+'down'='SET-DOWN'
(Other definitions for set down that I've seen before include "Drop (passengers); write" , "position of losing tennis player" , "Snub" , "Put into writing" , "Placed" .)
