When properly connected, my Roku starts up but has no signal out to the TV. It is connected to a sound bar's HDMI input. If I connect the TV directly it comes up just fine. If I then reconnect it to the sound bar I get a picture and sound and all is good until I have to power cycle the roku for some reason. My first Roku used to come up green sometimes and that was fixed with a firmware update.
Is this a known issue?
