I am having issues viewing certain channels after the heavy rain in North London

[Tenakha]

Most channels seem to work, but ITV1 HD gives this error:

This channel is currently affected by a problem with your satellite signal.

Please advise how I should proceed with this issue.

If a message displays “no satellite signal” firstly check that the connections from the Sky dish going into the back of your Sky Q box are still finger tight. Otherwise it’s likely to be a dish alignment issue so check the troubleshooting in this link

It may then give you the opportunity to arrange an engineer to check the alignment of your dish. If it doesn’t you’ll need to contact Sky to book an engineer appointment.

If you are connected to a communal dish you need to liaise with your building management company / landlord who will have their approved engineers to contact.

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