Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
I saw your post and I have the exact problem. However, I could not bring up your solution. Did you find an adapter for your Roku? My last Roku had round plugs but the new one doesn't. My TV only has plugs for round shapes. Sorry I am TOTALLY out of my league when it comes to this stuff. Mary
For clarification, Roku devices do not use the USB port to connect. The TV USB port can only be used as a power source for the Roku device, although we highly recommend using a wall outlet to power all Roku devices.
In regards to how to connect a Roku device, most of the Roku devices (especially the newer models) will use the HDMI. Select older devices (which seems like what you had last) will use the A/V plugs.
