I think there may be an anagram of something including SEE IF TV, which suggests it may be six feet five, but I'm stuck on where the X comes from!
Does FX have something to do with amplify? If so that just leaves IE , which means 'that is' and could be the ''being" bit.
This has been on here a few times over the last week, and other posters have put "O" as the second character of the second word. I have already filled two sheets of A4 with possible anagrams etc,
Incidentally, the clue is as given above, namely:
"Being very tall, see if television is reboxed and amplified"
Ah, V for very. Amplified in terms of expanding the Roman numerals.
Can see it now but wouldn't have got that- a bit different from the cryptics i do.
