TV freezing

[pjc8]

I have Sky Q. Internet connection is fine but pictures is briefly freezing every few minutes on all Tv channels. Have rebooted the box several times but that has had no effect. Any suggestions welcome

It doesn't use the internet connection for live TV. I would get the dish checked.

Thanks. I had not realised the feed still came from the dish. Turned out a tree was brushing against it so with some pruning everything seems ok now.
