After Roku device activates TV goes black with audio on
This is different than that black flashing etc. I am using a stand alone Roku device. When I activate the device the TV screen shows the Roku channels and the TV screen is clear. But when I press Netflix or some other channel the screen goes black but I started hearing the audio if it happens to be on on that channel. I know its not the TV, I've been using the Roku with it for a couple of years and the TV has no problem when the main Roku home starts up.
