You didnt do anything wrong. Electronics dont break easy like that from what you did. The problem is the hdmi 2.1 and hdmi 3 port on the tv itself. Earc isnt working currently and its worse after the current update. Also, 4k 120 does have flickering issues. Hdmi 2.1 port (4) and port 3 (earc) are currently malfunctioning. Samsung is assumingly aware of the issue I guess but no update on whether they are gonna fix it soon. I really hope so. Im gonna sell the tv as soon as the the new miniled series comeout. I have the q90t 65 inch. I hope to sell it around 1500 bucks and get the Qned 85 or 90 when it releases. HDMI 2.1 should be fixed on those.
