Some channels not getting signal

[DonnaG291]

We have had our Sky Q box installed in our new home for about 3 weeks now, everything was fine.  After installing one of our Sky mini Q boxes in another room yesterday we noticed a number of channels are showing no signal.  BBC1, Channel 5 and others. Across both boxes   We have the UHD package and service checker says all good.  Done all the usual checks.   Anyone else have this issue?

”No signal” tends to be a message from your TV. A “no satellite signal” message relates to your Sky box.

If it displays no satellite signal take a look at the troubleshooting on the appropriate section of this link.

You may then need to contact Sky and arrange for an engineer to check the alignment of your dish. Be aware that if you’re on a communal dish system you’ll have to contact your landlord or building management company rather than Sky.
