Is it the TV set that is losing the signal @Martin84 ?

Does is say No signal or No Satellite signal?

No it says it has HDMI signal then 10 seconds 10 says loss signal. I have swapped HDMI ports with another an still does the same nothing wrong with the TV HDMI port as othe things work when swapped.

How long is the HDMI cable? - It should be as short as possible (<<5m) and depending on the resolution (4k?) you are trying to get the TV to display, as high a rating as possible. 

Generally:

Standard HDMI = 720p or 1080i at 30Hz

High speed HDMI = 4k or 1080p at 30Hz

Premium HDMI = 4K with HDR up to 60Hz

Active HDMI = cable fitted with booster to cover longer distances.

Try setting the Sky output resolution to a lower value (eg: 1080i) and see if it still does it.

The HDMI cable is 2m long the sky q box worked 3 days ago.

Is it possible to try another source like a laptop on that cable?
