My Roku TV TLC brand even though it has an AV input, does not show it when I go to settings - input - . I scroll, but AV input does not show up at all. I also tried a HDMI adapater to access the HDMI ports but my TV failed to recognise the roku and just gave me the message "is the device on? no signal". So frustrated after spending all afternoon trying to set up. Almost ready to get a new TV. My Roku TV is model S-series brand TLC
Thanks for the post.
When you go into Settings > TV inputs what do you see? Can you provide us a screenshot of the options that are available to you?
With more information we will be able to assist you further.
Thanks,
