Not getting certain channels bbc1 itv loads what’s going on

Why aren't I receiving bbc1 itv channel 4 and loads other channels just say no signal ?

A message displaying ”No signal” tends to be from your TV, so possibly not being on the correct input (check the HDMI cable between the Sky Q box and your TV)

A “no satellite signal” message relates to your Sky Q box, so firstly check that the connections from the Sky dish going into the back of your Sky Q box are still finger tight. Also check out the troubleshooting on this link

It may then give you the opportunity to arrange an engineer to check the alignment of your dish.

A misalignment is not necessarily something that will be visible to the naked eye and could only affect one or two channels.

If you’re on a communal dish you’ll need to liaise with your landlord or building management company who will deal directly with their approved engineers.
