seems they dont know what they are doing. since the sound only comes in netflix app, its obvious its a software issue and not a hardware issue!! otherwise the buzzing would be apparent all the time or in most playback apps. it seems like, as mentionned above, turnin on or off LED clear motion can make the sound dissapear. in my case, if i turn it on the sound goes away, as soon as i turn it back off the sound comes back strong just like before. so definetly its a software issue
The high frequency noise problem on the 75" Q80T has been improved and fixed on the latest firmware version 1402.1. You guys can manually update your TV by loading the firmware to the USB first if your TV hasn't already updated on its own.
I have this exact same issue with my newly bought QE75Q80T
Easiest way to reproduce is to start the ambient feature. Because the noise/buzzing/coil whine begins immediately.
However, I downloaded the 1402 firmware to usb, extracted. Yet the TV cannot find any updates. It just says no updates available.
Files are extracted in the root drive, and not placed under any other folders.
I have tried 2 different and formatted (Fat32) usb drives.
And i have tried them in both USB-ports of the TV.
What am I doing wrong?
