Carnmoney Transmitter: I have a TV tuner and a recorder tuner, and both cannot view ITV and CH4 Standard Definition channels on the PSB2/D3+4 mux (C40). All BBC is fine and all High Definition is fine. It has been this way for several days. A re-tune has not solved the problem, but only completely lost the affected channels from my TV. We do not get all channels on HD, e.g. ITV4, Film4, etc.

Timothy Davis:
The transmitter hasn't been currently or recently listed for Planned Engineering and I can't find any reports of outages. Have you tried a manual retune on C40?
If you've tried that with no success, what signal strength and quality figures are you getting for the other muxes?
Check all your connections and coax plugs for corrosion etc. Make sure your aerial looks intact and still pointing in the correct direction. Check your downlead is secure and appears undamaged.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.
Have you changed anything in your set up prior to this problem arising?
