My home theater when turn on state that it activate "protection on" and the shut down

The unit has DC Offset, meaning a damaged amplifier. This issue will not allow to unit to turn until the damaged is repaired.
If you are interested in having your Samsung repaired, please look to my website at audioserviceclinic.com. Thank you.

The problem is with the amplifier overheating so the system shuts down to protect itself.

Make sure the ventilation fan is not block or obstructed.

If this is OK then contact your supplier with the equipments warranty.

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.

Try to Unistall by using the install disk. It should detect a previous installation and ask if you want to Install, Repair, or Uninstall.

If that fails, download and run CCleaner - Use the Cleaner and Regisrty modules default settings
