Dishuser it would be good to know what cables you used I to use a Samsung 2.1 soundbar, I got the power station set up via a different hdmi port first no issues. Plugged into soundbar soundbar is plugged into Arc port as per normal for Atmos sound. Initially all seemed okay but after a few minutes my tv screen started to blink on and off rapidly then the power station lost the signal from the power station Nvidia shield no issues like the above at all
