Today I was moving around my living room setup and had to unplug my Roku. When I plugged it back in and tried to watch Roku I get audio but no video. I get video output on the main menu and can see just fine inside any app, until I play video. Rebooting Roku and/or TV did not help.
To fix Roku audio no video unplug the HDMI cable from the TV then plug it back in.
