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.
I am having this same problem with a new Roku Express not working on Vizio XVT553V. If I do a device on the TV search it finds the Roku, but no matter which HDMI port I plug the Roku into, TV says "No Signal". Any ideas?
Have you tried using another HDMI cable to connect the device to your TV? Have you also tried connecting the device to another TV to see if the device is able to connect? If the device is able to connect to another TV, then it is likely an issue with the TV connection.
I have tried the device on another TV and it works. I assume it is an issue with the TV connection, but was hoping I could get some help troubleshooting it. If the TV can see the Roku, then it would seem that the connection is functional right?
I was having the same issue with a Roku+ Stick. The problem seems to be whatever switches and powers the HDMI ports on Vizio TV's specifically. It's not the Roku device(s)!
I had to unplug the Stick+ power and the TV power (from the wall). Then I held the All In One brand remote for TV power for 30 seconds to discharge the TVs capacitors I'm assuming?
Plugged the Roku power back in first then the TV power. Plugged the Roku back into the TV powered on both and it worked, began updates, etc.
I was afraid I would have to get another TV but this worked so that's money back into my pocket and everything works fine including power OFF/ON as well as Volume Control and Channel Changing. Hope this helps someone out from their frustration.
