This definately means that you have a positve and negative speaker wire touching somewhere. First thing to do would be to check all connections at the speakers and on back of receiver and make sure all wires are seperated. This is a common problem if two wires are touching each other. If you check all connections and they look ok and you still have same problem you need to start unhooking all wires and hook them up one at a time and turn on system. If it works with one speaker then try hooking up a second speaker wire and so on until it gives you protection message again. Basically process of elemenation. Once you says that protection message you need to replace the last wire you hook up all together as you could of damaged it when running speaker wire or it could be a defect in speaker wire.

"S-Protection"


That stands for speaker protection. Either you are playing the system too loudly, causing the amplifier or speakers to overheat, or there is a defective speaker or a short in the speaker wiring (where the two wires are touching each other).

If you've disconnected the speakers and the fault is still showing then the fault is internal with the Amplifier and it's shutting down to protect itself from further damage.

Your only solution is to remove the cover and have a look at repairing it yourself or take it to a repair shop.

I have samsung HT-TXQ120 and when I try to turn on DVD system,on the screen shows PROTECTION ,And then turn off ,I don't understand why ? thanks


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for ntermittent shutdown.

When pug it in show protection on the screen and blink.


Disconnect all speaker wires at the receiver then turn it back on. If it stays on, your receiver is ok and only protecting itself from damage due to a shorted wire or speaker. Once you've determined that the receiver is ok, reconnect your speakers one by one and test by turning the receiver on. You will either find that you've fixed the problem by re-connecting neatly all speaker wires or you will find a bad wire or speaker. If you still need help, post a comment and I can help you troubleshoot further. Hope this helps

I have a samsung home theater system HT-X70. After 10 to 15 minutes the word protection scrolls across the screen then goodbye and finally the unit shuts itself off.


ther is dc voltage applying your speakers by amplifire itself and turn on speaker protection circuit itself.
it can be happens because
1.loose connection in amplifire board
2.faulty output section of amplifire
3.short circuit of speakers
4.error detecting circuit faulty.
if youcan open the cover and clean the circuit for dust and resolder the circuit with 30 W soldering iron cairfully.if you want the more asistence please come again
ican hlp you more.

PROTECTION MODE


The unit may be experiencing an overload caused by a short circuit, internally or externally. Try disconnecting all the speakers, then turning up the volume. If nothing happens, connect one speaker at a time and turn up the volume to see if you get more sound. You may have a speaker that has shorted internally and this will help you discover the bad one. However, if when you have all the speakers disconnected, and the unit still goes into protection mode with the volume up, then there is a problem with the unit itself.

Hope this helps, and please rate my advice, good OR bad.

Good luck!
