I don't know if anyone can provide some guidance. On other TV's in the house we used to get OTA channels on those TV's without the set top box. Suddenly when the tech came to add a second box to our bedroom the OTA channels on the other tv's went away. All of our other TVs are HDTVs so that's not the issue. I wanted to see if anyone has had experience with this and what did you do to get the OTA HD channels back on the tvs without the stb. Thanks for your input.
