Gary : Could you correct the postcode you entered into the site. It looks as though you missed the digit for the last part of the postcode as the terrain plot and uk checkers think you are in BS3.
StevensOnln1 has provided the most likely explanation, however if you have an HD tuner and were receiving COM7 on UHF33 satisfactorily before the change on 27th Feb., then there may be another cause.

Since the re-tune we have lost ITV (inc 3 - 8) through our LG Smart TV BUT we can receive these via our old Panasonic DVD. Have done auto and manual retune for 49, 54, 58, 48, 52 and 56. Any ideas most welcome. Thanks.

M Moppet: ITV// haven't changed at yet (the PSB2 doesn't change until next year). Try retuning with the unplugged to clear your existing tuning date, then plug it back and try a fresh retune.

Hi, I've been reading the pots with interest as we have lost all associated with COM5. I've replaced our with a high wide-band, replaced the co-ax with new end connections. We've re-tuned without the aerial plugged in and re-tuned with the aerial lead connected. After all this expense and time we still can't receive these channels, getting frustrated now! We use the .
Any further advice greatly appreciated.

StevensOnln1:

Thank you very much for the . The in use has been in the for at least 10 years, so maybe a new purchase for a aerial is needed.

Interested in what you said about contacting advice line as I don't have or , just Freeview.

Will let you know how things progress, especially in the light others are complaining about the same problem.
