My BCD-3 has performed flawlessly since purchasing in January 2022. Yesterday the "Tray Error" message appeared when switching it on and tray wouldn't open. Tried to put it back into standby, display showed "Shutting Down" but unit wouldn't shut down. Had to turn off at mains. I assumed it was the drive belt as I thought I could hear a faint click when pressing the open/close button, but with the unit being "stuck" in shutting down mode perhaps it's something else? Thoughts welcome before it goes back to dealer next week, under warranty.
