We understand you are having trouble with your TV's buzzing sound, and we appreciate the steps you took to resolve it.
For clarification, does the issue happen on a Roku TV? If so, we recommend contacting the TV manufacturer to see what options or suggestions they can provide.
Each Roku TV manufacturer offers direct support and warranty services for their Roku OS products.
