We just bought a QLED Q80T TV and set it up yesterday. There is a terrible buzzing noise when using the built in Netflix app. It makes it impossible to watch. I've read that this is due to a firmware update from Samsung. When will there be a fix for this??? Makes me want to return this TV and go with a different brand! I've tested Netflix using our old Apple TV box and it works fine. So it's definitely the app that comes pre-loaded with the TV.
The buzzing is regardless of the sound output. I have done it with and without the soundbar. With the volume turned all the way down, you still hear it.
It is any time the Netflix app or Ambient Mode is active. The pitch of the noise definitely changes dependent on the brightness of the content on the screen. I opted to not go through the hassle of returning and repurchasing the TV because it sounds like there is a good chance the new one would just do the same thing.
Recently purchased this TV from my local store in Sydney Australia and I also have this annoying issue. Only happens when using the built in netflix app. I was tinkering around and noticed that when you enable the Led clear motion setting the noise disappears. Enabling this however drastically reduces the screen brightness. Hopefully a firmware fix comes in soon. This definitely is unacceptable for this level of TV.

Regardless of where I am in the world this issue appears to be on Samsung Q80ts around the world. There is also no forum page on the Australian Website so I come here as a last resort. Glad to see so many users have reported this issue so hopefully you guys actually do something about it instead of tell me where I should and should not be posting.
I have the same issue while using the Netflix app. Every other app doesn't do this. I contacted Samsung and they're sending a technician. But, I feel like they will be unable to fix the issue.
I just bought the Samsung Q80T on July 1, 2020 and have the same issue with the built in Netflix app AND Ambient Mode. It's insane that this hasn't been resolved yet. It's definitely something that makes the primary content we watch unusable as well as one of the main selling features of this TV, Ambient Mode. It would be terrible for even a cheap TV to have this issue, never mind an expensive one like this. If you haven't bought it yet, think twice before buying this TV. This isn't the only surprise issue I've had in two days of owning it.
I just had my panel replaced due to a banding issue, and i have just discovered that I have this coil whine issue too when opening the native netflix app. The coil whine doesnt occur on any other app including live TV. Potentially this may be an issue with the latest updates as the new panel that I received has ver 1301.4 whereas my old panel which didnt have the coil whine was ver 1115.5.
