On Friday the signal came back and remained, until last night, now it has completely gone again. I had booked for an engineer to check cables etc, but as it came back clearly this is not the problem. Brian, I have checked all the things you have said but nothing makes a difference.........????

Leanne: In that case, you probably do need an engineer to check your equipment.

I seem to share a similar problem to that several other people have described. Currently reside in PE8 where until the last month or so I received near perfect freeview reception - it appears to be mostly Mux 2. Nothing has changed in my set-up. Signal Strength on my Humax PVR has dropped from a minimum of 60% down to 40% and quality of signal varies wildly.... Is this how its going to remain or is this a temporary problem?
Any Ideas?
