Sorry to hear you've had some trouble setting up your Soundbar 500!
It should be as simple as connecting to the HDMI(ARC) port on your TV, then adjusting your speaker settings. So I'm able to look into this further, would you be able to let me know the model number of your Panasonic TV?
Have you heard anything from Panasonic yet, signaling any compatibility issues or something similar?
