I am saying I have got the 4000T, so I know what I am on about. But in your last post you said, Or it may not be the loopthrough - see Graham's post above. Thats what got me as we are talking about it, and I am saying it seems strange that the 4000T as the same problem with signal to the TV.
Yes, it sounds like the same problem in both models, and very likely the same cause, but what exactly is the cause has not yet been determined. Two possibilities - a bit of experimenting needed to see which fits.
