Most likely. It is probably in some kind of protection / "get me repaired at a really high cost" mode, this would explain why you had sound until you restarted it and it ran a brief diagnostic.

I don't think you'll be able to claim this on warranty as it is accidental damage, not a manufacturing error, but you never know! Maybe your home insurance will cover it.

Call Samsung and see what they say, the might be able to repair it for you or quote you the cost of a replacement.
