I am miles away from the transmitter but only recently have lost Ch59, well not completely, my PVR and a STB have lost it, but the TV is still receiving it perfectly despite the aerial being at the end of the daisy-chain via the other two. Might rig up an aerial amplifier tomorrow and see what happens.

Paul: The services not on full power have frequencies that are still in use for analogue services in neighbouring transmitter regions and can only be put at full power levels when those regions switch.

Hi Paul
Doubt if you have aerial problems, if anything you maybe receving to much signal which gives same symptom, but i doubt this due to the fact you were ok before the change on the 11th.
More likely proberly pulling from another transmitter.
A quick fix for you is just auto scan with aeral diconnected to clean it out, then auto scan again and reconnect aerial when its about 6o% through its scan, hence it should only load mendip.
Otherwise load manualy.
Kind regards
Dave

Sorry Paul
I miss read your post.
Oviously check your connections, but at a guess unless you got faulty receiver id say you may well have to much signal going into it.
If you dont want to call anyone out for a meter check, maybe worth hooking another recevier to your aerial.

I've retuned all our TVs/digiboxes since 11 Jan, and all except our main Panasonic TV seem to have picked up all channels again from the Mendip transmitter. Humax PVRs seem OK, but the Panasonic TV is now not receiving via its own tuner the channels transmitted at a lower power (Channel 12 - Yesterday, etc.). We live in Compton Dundon, near Street, and have had no problems receiving channels to date since digital switchover last year.

Martin Lofthouse: Yes, some people will not receive Multiplex COM6/ARQB until later in the year because of the changes.
Make sure you have tried this My Freeview box has no EPG, is blank on FIVE, ITV3, ITV4, ITV2+1, has no sound or the channel line up is wrong | ukfree.tv - independent free digital TV advice first, and also checked Single frequency interference | ukfree.tv - independent free digital TV advice .
