This happened to us today. I unplugged the unit, waited 10 mins, plugged back in, turned back on (from the unit, not from the remote), got the same "protection" message, turned back off and on again, and that time I quickly pushed the "function" button (again, on the unit iteself) and kept pressing until I got to the "radio" function, and suddenly I could hear sound again. went back to the dVd and we can hear again as usual! Hope this helps someone. Worked for us.

Usually a protect fault will indicate a bad transistor in the amplification section. I suspect that the control circuit is sensing a fluctuation in the power supply and going in to protect mode. (assuming that the protect circuit itself is working properly) If a voltage is too high the unit will go in to protect mode to prevent damage to the speakers and the rest of the unit. I would take the unit in to a local repair shop and get a estimate of repair charges. Expect a 60 to 80 dollar repair charge depending on how many parts need to be replaced and what the repair labor rate is in your area. Hope this helps.
When your home theater's display reads PROTECTION, it means the home theater is over heating and the unit will shut down to prevent any damage. This can happen if the unit is stacked along with other electronic devices or the unit is in an enclosed area that prevents the unit from cooling properly. To decrease the chance of overheating, relocate your home theater to a more open area.
If the home theater display reads PROTECTION every time you turn it on, no matter where or how the unit is placed, it needs service. To set up service call Samsung Customer Care at 1-800-SAMSUNG (1-800-726-7864). Have your model number and serial number on hand to set up service.
Hey guys, just had the same problem and found out it was because I had disconnected the central speaker. This it was creating a back impedance or something and reonnecting did the trick! i.e. check your speaker connections and check that they work... duff speakers could cause the problem too!
Wow, doesnt sound good. My only thought is that on new devices they often have tape and cardboard inserts to protect the device for shipping. Make sure there isnt any tape or packing material stuck somewhere in the device. Otherwise it must just be a bad player. They shouldnt have any problems exchanging it since you just got it. Good luck!
I found this online. Don't know if it helps you guys or not?
1. Remove any discs from the tray 2. Flash the RAM (disconnect from the mains for 30 seconds) 3. Plug it back in, switch on from the remote 4. Wait for "No disc" message 5. Press Enter. 6. Press 8,4,2,6,9 slowly. 7. Press Enter. You may need to repeat steps 4 through 6 before the try is open.
