2019 Q80R HDMI ports work then stop working

[Matcosby]

I've had this tv 5 months, I have two hdmi connections, sky q and a PS4. 

I turn the tv on and sky works fine, then flip over to the PS4 and all that happens is a screen with a PS4 icon and the sound of the PS4 but no picture. If I return to sky I get the same SkY icon sound b7t no picture......

if I go thru the connection guide and troubleshoot it suggests that it's working but once again it doesn't. 

I have attached a video, I'm at a loss

I have the same issue with my Q80R. did you get a resolution?
We turned the tv on only at the weekend and out of 6 turn-on's, 3 of those have been with the problem you describe. Not a happy camper at all - and that's after having to have the Samsung engineer out to get the screen to power-up. Wish I had gone back to Sony.
