Only recently has Roku themselves started selling TVs with Roku capabilities built in. These are referred to as "Roku Branded TVs", sold through Best Buy.
Other than that, a number of TV manufacturers have licensed Roku technology for inclusion in some set models and market them as "Roku TVs" (note not "Roku Branded TVs"). Roku doesn't manufacture these "Roku TV" sets or their remotes, it only supplies the Roku operating system. Hardware issues with these sets need to be referred to the manufacturer of the set.
Manufacturer support contacts for Roku TVs can be found in this support page: https://support.roku.com/article/115006475047
