Bought around three years ago. Worked for a while. TV doesn't turn on soundbar anymore. Replaced HDMI cable didn't fix. Tried unplugging TV and speakers, didn't fix. Updated TV firmware didn't fix. Tried optical have to manually turn on speakers and adjust volume on soundbar Polk and TV remote don't work. Bluetooth TV remote will only change volume over a limited range doesn't display volume. Rarely shows connected to tv.
