I was having the same intermittent 'no signal, weak signal' problem with my FVP-4000T on most HD channels. I tried an attenuator which did not fix the problem, in fact, it made it worse. The signal quality kept dropping from 78 to 0.
I solved the problem by replacing an internal 5m aerial cable with a shorter 0.5 meter aerial cable between wall socket and the box which eliminated the problem completely.

Almost certainly a badly fitted or faulty connector on one end (or both) of the replaced cable. Usually a whisker of screen touching the centre core creating a low resistance (near short circuit).
