Buzzing sound
How do you remove the buzzing sound?
It sounds like you may want to have your plasma panel inspected by a Geek Squad Technician for further review. Without more information, we're unsure why this might be happening. In some cases, checking the audio cables to make sure they're snugly installed will fix that symptom.
Thanks for your support of Samsung products, and we look forward to assisting you further.
