Ultra V1770 - my first telly and Im struggling

[Exiled Yorkshireman]

Thanks Mike. I don't have a Pi 5 at the moment. My collection comprises a 1B, a 2, a 3, a $ and a 400. Oh! and a Pi Zero W and a couple of Picos. But not a 5. Anyway, onwards and sideways...

I'll certainly be cleaning the tuner soon.
