A:AnswerTo much Bluetooth going on with this unit for you. I have an HDMI from the DVD to a amp, Then an HDMI Arch to the Tv. I’m guessing you need to go from the DVD player with a HDMI into your Smart TV. Then Bluetooth to your sound bar.
A:AnswerMaybe you accidentally locked it, from child lock. Instructions say, you can lock this tray to avoid accidental opening of the tray. While the player is turned on, press stop, home, then top menu button on the remote to lock or unlock the tray. And I hope it’s not the batteries that are dead.
