I do not have the same unit but a similar experience with a simple LG DVD

I inserted a DVD in the tray and now it initializes fine.
My "guess" is that the CPU looks for a DVD in the tray and, not getting
the expected feedback, hangs.
This is probably a mechanical issue with the DVD mechanism but I was
satisfied with leaving a DVD in the tray to get to HELLO.

I suppose we could see software issues, since these are computers.

My blu-ray player can every so often get confused, I don't know if it's
consistent, but if I press the open button at the wrong time, something
seems to jam, and I can't turn it off or do anything, until I unplug it
from the line.

I haven't updated it since I found it, I think there might be an update,
so who knows if it's a software issue that's already been found.
