The document does not provide specific troubleshooting steps for a Samsung HT-DB300 system that shuts down and displays a protection message. Therefore, based on general information in the context, you should:

1. Turn off the unit.
2. Disconnect the power cord.
3. Contact the nearest authorized dealer or Samsung Electronics Service Center.

These steps are recommended when the issue is not listed or basic troubleshooting does not help.
