I may have accidentally discovered a partial solution to this. I changed the input to HDMI 1 when I connected a Roku. After I disconnected the Roku, I left the input on HDMI. Now when I turn on the TV, it says no signal detected and scrolls thru some beautiful wallpapers with no annoying hissing. Give it a try.
