Purchased AGPtek HDMI converter. Will that work to install Roku Streambar to my old sharp TV? @Tivoburkee
If its has hdmi input and then has RCA output, it would allow you to see your Roku soundbar on an old tv. You can only play programs from channels built-in to the streaming device in the Soundbar. You won't be able to hear sound from other devices connected to your tv through the Roku Soundbar.
If the convertor is RCA input to Hdmi output then that is useless. See they're not backwards compatible.
Simple answer: probably not, and would not be making the best of the soundbar even if it did.
Time for a new TV, or maybe a computer monitor with HDMI input (smaller, cheaper, stream only).
