This has happened to 2 consecutive 6900 tv’s I took first one back happening again this is Samsung product failure. This needs to be taken seriously and investigated
Same issue here, TV is like a week old, our first Samsung. Does it with AppleTV 4K with a brand new high-end HDMI directly into the tv; and my Xbox One.
Been digging to find an answer and this is really the only thing. Someone elsewhere posted a photo but it was never solved.
