MBNA:
Neither Freeview nor the BBC are currently reporting any problems with the Hemel Hempstead relay (6 muxes) nor is it listed for Planned Engineering.
Have you got your signals back now? If you retuned when there was no signal it will have cleared all correct tuning and you'll need to repeat a retune when there is signal.
If you still have no signal, then check all you coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads can be a common problem, try swapping them. See what signal strengths (if any) and quality you are getting for the multiplexes shown in your TV's tuning section, this might indicate potential issues with your aerial or downlead. Also check that your downlead looks undamaged and that your aerial seems intact and pointing in the correct direction.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.
