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"


I have disconnected all wires from the back of player, and it still turns off and says "s-protection". If I unplug it and plug it back in, it will work for about 30 seconds then goes off. Would that mean there is a short inside the unit itself?

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.

I have a problem with my samsung ht-up30 home theather system. When i turn it on it only shows "PROTECTION" and turns itself off right after that. How to fix it? Regards!!!


The amplifier has a bad channel, or is bad itself. It is trying to either output too much current or is not putting out enough. If you have multiple speakers wired to one channel, you will either have to change the wiring to series(unit positive to first speaker red, first red to second BLACK, second red to unit negative) or remove on speaker. (If this is the case, then you might want to look at this. It is a tip/rick to place and properly/successfully run three subwoofers, but the main concept can be used on all channels.) If all channels are wired to he correct speaker, then the amp is in fact at fault.

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.

Protect flashing on screen


That is the system telling you it jhas shut down the amplifier circuit to protect itself from damage.
Check the speaker wires both at the back of the unit and at each of the speakers to see if any of them have come out or are touching anything they shouldn't be.

You may also have a blown speaker sending a short back down the line. So if you find no wires out of place, then disconnect each speaker and turn the unit off and on as you go until the message is not showing and sound is restored.

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!
