Set up Roku last night and it worked. This morning it doesn't. Have tried swapping out to different HDMI inputs and also to one that is working from my cable box. No dice. Thoughts? Can't find a phone number to speak with anyone one on one.
Can you be more specific? Do you not get any picture at all? Is there any light on the Roku that comes on when you connect the power? What's the model number written on the device somewhere?
If it's a model that uses a USB cable for power the first thing is to ensure you're using the supplied power adapter and not the TV's USB port.
