Blue Screen - No Signal - Recurring

[chadwick33]

We were having intermittent problems with the TV screen going Blue and saying No Signal.

Sky engineer eventually came out - said signal seemed fine but changed the main Sky Q box.

Now it's even worse and we are getting continual interruptions on certain channels.

Need to get this fixed asap.

Any help appreciated - struggling to speak to Sky.

@chadwick33  Out of interest are you on a communal dish or your own dish?

Interestingly, although it is a single detached dwelling, it is served by what the Sky engineer described as a 'communal' dish - but only serves us.

I have had it checked and the Sky man also said the Signal seemed fine.

Also, recently fitted nearby, but not obscuring it, we have a Starlink satellite broadband receiver/dish. 
could this be having any effect?

thanks
