Satellite signal problem

[MOA00]

Sky channels work for 5 minutes and then I get the error msg with a blue screen 

" this channel is currently affected by a problem with your satellite signal. For help press ? "

Reboot of sky mini box does not help

@MOA00 
Whenever a “no satellite signal” message is displayed 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.

It’s 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 may initially need to liaise with your landlord or building management company.
