I've had the same problem. I smelled something burning, PROTECTION came up on the display, and the sytem shut off. Initially, I thought it just overheated, so I turned it off for the night and tried it again in the morning. It stayed on for about half an hour, then the same problem occurred, without the burning smell. I called Samsung, they said the "fan was out," but that doesn't explain the smell. I wanted to check for myself, so I opened the casing, and indeed found a burnt metallized polyester film capacitor. Samsung obviously did not consider the heat level that could get through it, and thus used the wrong type of capacitor. I'm sending it back to get serviced, hopefully it will come back with a different capacitor.
Do you smell anything burning. This happened to me and I cut it back on. It stayed on for 30 secs or so and did the same thing. After doing this 2-3 times, I smelled a burning. Being a member of the Fire Dept, I didn't want to see my buddy's coming to the house, so I unplugged it. The next day, I took it apart and there was a burnt resistor or something under neath the fan. I took it back and they gave me a new receiver, but I'm expecting the same with this one.
Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.
Overloads can be from excessive periods of high output 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 hands-on tech.

I have the exact same problem. I thought it was over heating so I made sure it has complete space around it and it was elevated for maximum heat dissipation. Problem NOT solved. Im starting to think they underthinked the cooling of the system or the coding of the "protection". I've had mine for about 2 weeks now...and I'm gonna trade it for somethin else
I have the same problem with my HT-X50. Last night I could see and smell smoke from my entertainment center. At first I thought I would let it burn up the house and call an attorney. I decided against that stupid Idea. I unplugged and tried it an hour later,now it shuts off every 5 minutes or so. The led screen says "protection just before it shuts down. I am on hold now with Samsung. I have looked everywhere for a recall and have found nothing. I guess someone has to die in a fire before there will be a recall. They want to service it and return it to me I do not trust it. I do not think it unreasonable to not trust the unit in my house!
Hey I have the same problem. I just took my casing off and noticed it was the two capacitors right in front of the fan. So I took the board off and took them out. They were so fried I can not tell what kind of capacitor to buy to replace them. Just wondering if anyone can help me out. Also if there is a better choice than the ones that came in it originally please let me know.
Thanks a lot,
Adam
