If this unit stays on for 5 minutes, and it appears to be playing normal, a bad speaker could be the cause unless you are using speakers that are not compatible with this unit.

The specs on this unit are 100 watts per channel and require 8 ohm speakers. if you are using speakers that are 6 ohms or 4 ohms, you will overheat the unit quickly and it will shut down. It is not designed to use anything less than 4 ohm speakers.

If you are using the speakers this unit came with, or you know that the speakers are 8 ohms (it should be listed on the speaker where the wires plug in), go ahead to the next step.

The first thing to do is to unplug one speaker, it does not matter which one, just pick one to unplug from the back of the receiver or right at the speaker. If you unplug one right at the speaker, make sure that the speaker wires do not touch together or touch anything else, they must be insulated from anything metal or conductive.

After one speaker is unplugged, turn the unit back on and let it play normally the way it was when it shut down after five minutes. If the unit continues to play for a long time, at least 30 minutes or more and does not shut down on its own, you have just found the culprit causing your problem. Some speakers may sound like they are OK, but still can cause a problem.

If the unit shuts down again after five minutes like before, go ahead and plug that speaker back in and do the same thing with one of the other speakers.

Continue this process until you have isolated one speaker as being the problem.

If you go thru the entire process and it still shuts down, you may have an internal amplifier problem. It can be something as simple as some heat stressed solder joints that need to be reflowed, or it could be a bad amp IC. This unit uses 3 different amp IC's and it could be any one of them or a component in the amp circuit. Sometimes it can even be a power supply failure. In any case, if the above steps do not work, you need to take it in and be serviced. There are no other end user options to perform.

I hope this helps with your problem, if you need more help just ask.

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.

System turns off by itself


My unit said "protection", "goodbye" so I opened it up and found a capacitor to one of the speakers had blown, right by the fan. It's a 35 cent part and a simple solder job. The hardest part was getting the face plate off the dvd tray so I could get to the circuit board.

Please update your post with any Model Numbers that you can retrieve, especially the subwoofer. Off hand, and with the limited amount of information that you have provided, I would GUESS that your subwoofer is simply overheating, and is being shutdown internally, hence protecting the fuse because no short is detected. If you haven't moved and or vaccuumed/cleaned around or near your system regularly, dust, pollution, pollen...you name it, builds up and can easily prevent electronics from breeathing/venting properly.
