Yes. Include everything but the most important piece of knowledge. How to identify the defective component.

[@saphklein2381]

My best advice would be to remove the back of the TV as standard. If possible get a microphone so you can hear which component is the issue, you can also use a pencil to touch the components and see where the buzz is strongest.

Gracias 👍

Hi, I have an active subwoofer with the same whine. How did you determine the exact defective component? Thanks
