If you look at all the posts over this 20+ page thread, the one thing most people have in common is that they're using some sort of external sound system over an ARC connection. I do think it's Samsung at fault, as my previous TV never turned itself on with the exact same external set up. But replacing my old cable with this one certainly seems to help. https://www.amazon.co.uk/gp/product/B00DYQ2BOK/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 @userl523qwxaI6 I bought the same cable and it did not fix my issue. Sony soundbar and HDMI arc = switching itself on still... Ive had TWO Samsung people try to fix this and it still turns itself on. Turned off all auto updates/wakes/power saving and still does it. Only disabling hdmi arc on the soundbar works which is pointless because that’s why I bought it. Not or buying a Samsung telly again.
