Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
My mom has a older Vizio TV with HDMI but none of these are registering with the brand new Roku Express I just purchased at Walmart. When i change my source buttons to try and find it nothing shows up. I am using wall plug for electricity. What could be my problem?
First, ensure the Roku is doing something. There should be a light on the front that comes on and/or flashes when you first plug it in. If that's happening, do you have another device that you can use to test the HDMI input like a laptop or Blu-ray player?
