Cold as a TV tec? (6)
I believe the answer is:
frosty
'cold' is the definition.
(similar in meaning)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for frosty that I've seen before include "Lacking in warmth" , "Cold and unfriendly (glance or reception?)" , "Icy cold" , "Chilly in attitude, like musical snowman" , "showing little enthusiasm" .)
