Hi @Radon1818
Thanks for the post.
Please be aware that the Roku Streaming Stick (3600) is an older Roku device that is no longer under warranty. It's possible that the remote may simply be on its way out. If you need a replacement remote for your Roku stick, you can purchase a compatible remote on our Products page here.
You can also use the Roku mobile app as a remote. Here's a link to know how it works: How do I install the Roku® mobile app?
I hope this helps!
All the best,
Kariza
