Have Roku express connected to Samsung TV by HDMI and powered by TV USB. When I turn TV source input on to cable (HDMI) it plays cable channel 4-5 minutes then flips over to Roku. I then change source back to cable and TV stays there. Thought it might just be Roku overriding cable source as it connects to network but the problem happens even when I switch source on start from Roku to cable.
