Thanks for posting here in the Roku Community, KJ70!
We appreciate you informing us about the issue you're encountering with Roku Ultra, having a loud buzz when turning it on, and we'd like to keep an eye on this so we can investigate further.
Could you please let us know if you have tried rebooting the device? If not, we would recommend doing so, to see if the issue will be resolved.
Here's how...
You may need to restart your Roku device to get it working properly again. To restart it, either unplug the power cable, wait a moment, and then reconnect it. Or use the following steps to restart it from the Settings menu.
- Press Home on your Roku remote.
- Scroll and select Settings.
- Select System.
- Select Power. If you do not see a Power submenu, skip to the next step.
- Select System restart.
If the issue persists, try it on the other TV and see if we can isolate the problem if it lies within the TV or in the device. If you have observed that the behavior continues after connecting it to the other TV, get back to us and let us know more about your device details below.
- Roku device model, serial number, device ID, and Software Version. (these can all be found in Settings > System > About)
- Tracker ID (when you see this issue occur, press the Home button five times, followed by the Back button five times, and provide us with this ID)
- If it is happening on a specific channel, please provide the Channel build version (Highlight the app from the Home Screen and press the Star * Button).
Please keep us posted so we can help you further.
Thanks,
Emman
