Welcome to the Roku Community!
I'd be happy to look closely to see how we can help get you up and running.
Here are a few questions here to better understand what you're experiencing:
- How are you powering the device? Is it plugged into the TV USB port, or is it plugged into the wall outlet with the provided cables?
- What Roku model device are you using?
- Have you tried using another HDMI port on your TV as well as trying your device on another TV to see if you are seeing the same issue?
- What troubleshooting steps have you taken so far to try to resolve the issue?
With more information, we will be able to assist you further.
