Solving playback issues

[Madking1]

Have a Roku tv 75R6A5R and when I’m watching something and the screen is black there is a high pitch squeal. It’s only on a black screen

I have updated with latest software. I have done factory reset, network reset, system reset. Have unplugged and plugged in again. The noise occurs on black screen either when a app is loading on on a movie or tv show with a true black screen  

I can record a video of the sound if that helps. 

edit: I have a Roku soundbar connected but sound comes from tv. Unplugged soundbar and it’s not the  soundbar.
