You many now have "too much" signal. Remove any aerial boosters. Use male-to-male coax connectors for shortest run directly from aerial to nearest digibox or receiver. If no signal, do a factory retune, manually by channel if possible. If joy, you have too much signal. Permanently remove booster amplifiers. Consider fiting new sat-grade coax. If inaccessible masttop booster : take great care or consult a professional rigger. If you have a reasonable view from an upstairs window in the direction of the Mendip mast, try pointing a temporary aerial out the window to ascertain whether you have a strong signal or not. If only ch67 remains elusive, see issues relating to its temporarily higher frequency on this page. Confer with neighbours to see if they are similarly affected.

ITV3 transmitted from Mendip is this on low power? Receiving channel ok at SP8 5PY but 1.5miles down the road at SP8 4AD no luck at all. No apparent problem with other channels.

about 10 days ago I lost Yesterday
I retuned and it came back
3 days ago I found I had lost Dave on Ch 19
I have retuned several times but it does not come back
I used to have about 110 channels, now I am down to 85. It makes no difference whether my loft amp is on or not
Ilive in Castle Cary and have a communal aerial system cabled into the house.
How can I get Dave back? I miss him

My TV loses most of the channels, ch. 10 and upwards when I switch to stand by. I have to retune every time I switch on. Any advice would be much appreciated. Aerial is on roof.

Brian: You presumably have a box that stores the first version of the channels that it finds. Due to the hot weather, the signals from distant transmitters have been coming through a lot more strongly and were - presumably - strong enough to be detected.
See Digital Region Overlap for tips on resolving this problem, although it may well go away if you retune once this spell has passed. For now, you may find the correct service somewhere else in the channel list, e.g. around 800.

Son in Law: The SDN multiplex, which carries ITV3, is at full power since last week's retune.
The prediction at SP8 4AD is much better than that at SP8 5PY, so I would expect something different in the receiving set-up.
C48 is in Group C/D, but only just. If the aerial is quite old it might not work very well down at that frequency - the groups were extended to squeeze in Channel 5 when it launched in 1997. It might be worth going wideband now, as there may be new services as far down as C33 (although this has not yet been finalized).
This frequency hasn't ever been used before at Mendip. If this is a residential block with a communal aerial - bird's eye view on Bing suggests it might be - it could be a channelised system and the system would require retuning to amplify this channel rather than the previous location. The levels might need to be recalibrated too, even if it isn't channelised.
The overall signal levels are substantially increased since last week, and that could push a system that was working into having too much signal. See Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice for more information. (SP8 4AD) (SP8 4AD)

Mr. J Talboys: This can often happen if you use the 'automatic search' facility and the box has run out of permanent storage memory. Or, some boxes apparently don't overwrite the permanent locations with this facility.
At major retunes you are recommended to reset the box to a blank state, using the Factory Reset, Default Setting, 'Reinstall All Channels', Full Retune, First Time Installation or Virgin Mode options. Different equipment calls it different things. There are retune guides for some equipment, and full manuals for some others, at TV Re-tune .

Since recent changeover I cannot get all of the channels I was getting before. I cannot get ITV3 or Dave. Also when try 813 BBC News channel I get G O L D scrambled. So what has gone wrong?

Mike:- Thanks I will retune in a day or 2. It isn't a box though it is thr TV. I may buy a freesat HD box though and be done with it as the pick up is suspect and I have a sky dish on the wall already.
