MyCinema600isBroken

My Cinema 600 sound bar is connected via HDMI. LEDs had been working and I turned the LEDs off via the remote control. I had already connected to the sound bar using the Klipsch Connect app. The problem started when I tried to re-connect with the app and the volume cut out and the Bluetooth on my phone sent me a pairing request which failed. stating that the PIN was wrong. The volume also reset to zero. Now: The volume buttons for the sound bar and sub work on the remote. The buttons on the sound bar work. The LEDs will not turn on via the button on the remote. Cannot pair with Bluetooth by pressing the button on the remote. The app sees the Cinema 600 but, reports an error when I select "Setup". I uninstalled and reinstalled the Klipsch Connect app and tried a factory reset but, no change. The device is out of warranty. Any suggestions?
