Hi @Perki,
Greetings from the Roku Community!
We will be glad to assist you with your inquiry, but we will need more details. What device are you using right now? (e.g. Roku Express, Roku Streambar, Roku TV – specify TV). In the meantime, please try to unplug the Roku and the Samsung TV for 3 to 5 minutes then replug it back again.
We look forward to hearing from you soon, and we'll continue to assist you further.
Regards,
John
