I have an ONN TV with builtin ROKU.
It will not find any channels below channel 22. I do have an an outside antenna and it does work on all other roku TV.
It will only find channels above 22. Anyone have the same issue that knows how to fix?
Thanks for the post.
For clarification, are you connecting this Roku TV to the antenna directly or are you using a splitter? Have you tried rescanning the channels on your Roku TV to see if that helps?
