Bethan Williams: If the box has a manual tune function, then you need to go through to it and enter UHF/RF channel 57 for BBC from Llanddona.

Go to ITV1 and bring up signal strength screen and it should say that it is tuned to C60 for Llanddona. If it's not, then let us know what number it is tuned to.
