I have owned many roku devices and have never had any issues. I recently purchased a Roku Ultra 2020 a few months ago. Recently the device would stop for no reason and reboot. Now it is making a vibration that is coming from the Roku player (high pitched buzzing noise). Any ideas on what this is and how to fix it?
Is there a light showing on your device? 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? In addition, 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?
If you are unable to resolve the issue, please send me a PM (private message) with your Roku account email address, and include the serial numbermof the Roku device from Settings>System>About along with a summary of the issue you are experiencing. I'll be able to assist you further from there.
