Apple TV 4K (2021) producing green flashes on new Sony Bravia TV
I'm streaming 1080p movies (i.e., not even 4K) using a disk attached an Airport Extreme to a brand new Apple TV 4K, which is connected to the TV via HDMI. For some reason I'm getting green flashes/flicker appearing on the screen. The Sony is also brand new (model X85J). The new 4K Apple TV replaced an older 3rd generation Apple TV and in the 9 years I had it I've never had an issue. I saw an earlier post from Jan 2021 about this issue, but a solution was not offered (https://discussions.apple.com/thread/252317168?login=true).
Has anyone else run into this issue? Aware of a solution?
