LG SN7R, LG NANO91 & ROKU ULTRA ARC Issues

I've got the correct High speed HDMI cables, and I have the ROKU Ultra connected to the HDMI IN on the SN7R then the SN7R (ARC Out) to the ARC In on the television. The Screen blinks then goes blank. I've tried everything.....Help, please.

 

If I connect the Roku directly to the TV (HDMI 1) then the TV ARC (HDMI 3)  to the soundbar ARC everything is fine. Thank you!
