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 old Vizio tv is not working with my Roku SE. I connected my power source to an outlet and my HDMI cable to my tv but it does not work, all the input channels say no signal. I don't know if I'm doing something wrong or Roku SE is incompatible with old Vizio TVs.
For troubleshooting purposes, have you tried connecting your Roku device to another TV to see if you are able to see the device? If so, it's possible that your TV may not be compatible with the newer Roku device.
