Only happens on Prime. Roku Ultra with quality HDMI cable. When scrolling Amazon Prime looking for a show, each time I move right or left on a show banner the system goes black momentarily. Does it when moving up and down the menu as well. Does not affect streaming once a show has started. Occassionally, after several menu transition momentary blackouts it will cause a white snow screen on the TV forcing me to restart the TV, but not the Roku. After a quick TV restart it usually goes back directly to the Prime menu where I left off. Again, only on Amazon Prime shows menu. Switched cables, wireless network and HDMI ports and problem persists. Reloaded Prime and have latest Roku update. Any ideas?
