If you buy a HDMI to component converter it is certainly possible. Plug your streaming stick into the HDMI port labeled “HDMI input” and plug a component cable into the component ports labeled “CVBSLR output”. Route that component cable to your TV and you should be able to watch your Roku again.
If you don’t see any video, be sure that the converter is plugged in and turned on and that the component cables are in their designated color spots.
