Question about Audio Players & Recorders

1 Answer

I have a Samsung Home theater unit that displays the "Protected" message and then shuts down. I have had the unit switched with another one, replaced by Samsung and I still get the same message. Samsung insists it's the unit and wants me to return it for another. I don't think it is since I can unplug all the speakers and and the unit comes on. I then plug one speaker in at a time and turning the unit off and on, on three of the speakers it shows Protected. The speakers are what came in travel trailer that system is installed in, could they be bad or the wrong size, is the wiring grounded out?

Yes, it sounds wiring of one speaker got shorted/ grounded some where and causing "protected" message, basically its protection circuit that kicks in when it detects speaker wire shorted out.
Plug one speaker in one time and turn On unit until you find out what speaker kicks protection circuit in. Check that speaker wiring to fix the issue. As you said, unit comes On without speakers that means unit itself is good.
Hope these info will help you.
Thanks.

    This unit is in a Fifth Wheel travel trailer. To calrify do you think that the affected speaker is the wrong type, size, or do you believe that there may be a short, broken wrie somewhere along the way?

    I believe speaker wire got shorted because if speaker is wrong size or power, unit will turn off on high volume.

    I havn't ever used it at high volume. The speakers don't sound right. The unit has six speakers the front ones normally appear to be working correctly. If I unplug them and then plug in one of the back speakers they don't sound write but there is sound coming out of them. In this condition they do not trip the protected message. But if all are plugged in then they do.

    6 speakers system is actually surround sound system and all speakers wont give sound at same time. It depends on sound track that is recorded long with video that you hear sound may be few speakers to get surround sound effect.
    Front speakers are called main speakers that usually give more sound other than surround/ rear speakers. There would be one center speaker for vocal/ dialogue sound of movie and rest of speakers will give sound as per scene requirements.
    Try one speaker at one time and turn unit on to identify what speaker wire is causing problem. Unplug only that speaker and plug rest of speaker and play the unit.
    Check defective speaker wiring to fix the problem.
    Thanks.

Samsung Digital Home Theater System keeps shutting down not even a full minute after turning it on. What's the problem?


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.

"Protect" error - HTZ110


Home Theater System Is Displaying "Protection" spacer.gif As soon as the unit is turned on, the word "PROTECTION" will flash on the front panel of the unit and SHUT OFF. This error message usually indicates that the fan in the back of the unit is not on.

The PROTECTION feature automatically shuts down the unit to avoid further damage. The unit will need service if this error message is displayed.
