Samsung LED TV buzz(?) at certain sound frequencies

Dec 4, 2017 7:39PM PST

I have an issue with my Samsung LED tv where it sounds like the speaker buzzes at certain frequencies (very similar noise to if the speaker was blown). I have been searching for fixes, and the best solution I can find (along with a possible better description) can be found in the last two comments of the thread at the following link:

My question is, does anyone happen to have a picture of how they fixed their speaker buzz by reinforcing the speaker support within the tv?

I would probably suggest you to check samsung faq page or contact the samsung technical team for understanding about this in a easier way.

Is the LED "driver board" actually an "inverter" like used with CFL backlighting on LCD's? I'm wondering if some of these TV's with the buzzy speakers may have wiring running too close to a power inverter or transformer causing the buzzy speakers. I know if such wiring is running near transformers and inverters it can cause electrical interference in that wiring.

Here's youtube video of layout of LED board.
