Thanks for the reply Barry.
Its possible. We had some scaffolding taken down round about the time things changed and i guess a tap with a scaff pole would do it. It does, however, appear to be pointing in the same direction as our neighbours dish. I was hoping there might be another explanation as all the adjusting bolts on the dish are well rusted. Before I start with the WD40 is there any relevance to the fact that, on the manual tune page, the first two lines read:
Tuner Tuner 1 (Fixed)
Satellite freesat 28.2E
