Hi there, Thanks so much for asking about this. It looks like the TV is not detecting anything in the One Connect port. Check out this link to a similar issue posted in our QLED board:
However, I'd like to note that your model is not pulling up as a US model, and support for US products is the focus of this forum. As your device is a non-US model information is severely limited. We kindly suggest that you use this link to look for a support team in the area your product was manufactured for: https://www.samsung.com/us/common/visitlocation.html
Additionally, if you follow this link: https://r2.community.samsung.com/ you might discover that your nation provides its very own support forums, just like this one! Just look for the Community Option.
