Colin Berwick: There are no faults showing for Sudbury. Have you checked for any loose or damaged cables or connections behind your TV? Do not attempt to retune.

In CM7 - we seem to have lost all reception on C47 (682.0MHz), so we no longer have access to any of the HD channels that we could before. We have great reception on all others though, so is this a transmitter thing or an issue to look into at the receiver end?

David:
We need a full post code , not a partial, so that we can look up the expected reception conditions at your location. (A partial such as you have given covers several dozens of square miles and is insufficient to trigger the information needed.)
It is extremely unlikely to be the transmitter, no one else has reported any problems, so I suggest you carefully check all the aerial cables and connections. Unplug all coaxial plugs and sockets and then refit, that will clear any corrosion/oxidation from the contacts which is a common cause of the problems you report.
Then check what the signal strength is reported to be on all the multiplexes broadcast from your local transmitter. You ideally need it to be between 60% and 85% on all multiplexes to have sufficient to allow the TV to decode and not so much as to overload the tuner.

David . HD needs a bit stronger signal than SD . So its possible that there is a small fault in your aerial/cable/connections . Not big enough problem to knock out SD but making the signal too weak for HD.

I can no longer pick up LBC or Classic FM since the recent retune of these channels. I have done the reset procedure of pulling the aerial out of the back of my NOWTV box & doing a rescan. Everytime I do this it shows 2 iterations of LBC & Classic fm but neither of them supply any audio.
I believe I am picking up reception from the Sudbury transmitter & I live in the CM8 1XE area.

You should be getting very good reception from all muxes at Sudbury according to Coverage Checker - Detailed View
I'd try that Reset and Retune with the aerial unplugged again and perhaps at the end when it says no channels found, power it off, wait a minute, power on and check there are still no channels found, plug the aerial back in and do a new Tune for the channels.

Steve make sure you are using the right tuning mode . Some Freeview boxes have a complete retune mode and an 'add new channel mode '
