@DvdM are you talking about something physically stuck to the screen or bezel? Or something that is displayed? A picture might help.
Are you in Europe? The only references I find to that TV are in Europe. If so, you probably want to visit the Samsung discussion area for that part of the world. Since this area is for Samsung US products and services, the US users might not have the info you need.
Thank you so much for reaching out! This forum is for the support of US products and customers. We do not have the ability to support models outside of the US. There are differences between the US and International firmware, which we do not have access to. Since your product was purchased outside of the US, please visit the link below for support in your area.https://www.samsung.com/us/common/visitlocationsite.html
