Status update: After coming back to this issue after not doing anything for two weeks, now my Roku is working! At least it appears so....I get Netflix, and I'm into ten minutes of a YouTube video. So I won't be contacting Roku, or getting a new TV, after all. I don't know what happened, but I "won't look a gift horse in the mouth"! Thank you again, StreamerUser for all of your help!
