I just turned my DVD player off when my STR-DE545 was still in DVD input mode and it came up LOCKED, maybe the input that you are using is not receiving a signal?

Tips for a great answer:
No sound or only a very low-level sound is heard from the rear speakers.
>>> Make sure the sound field function is on (press SOUND FIELD - MODE).
>>> Select a sound field containing the word "cinema" or "virtual" (see pages 28-30).
>>> Adjust the speaker volume (see page 19).
>>> Make sure the rear speaker size parameter is set to either SMALL or LARGE (see page 17).
