When I press the power button Protection is displayed for a brief second and then the unit shuts down. Pressing power button does not do anything afterwards for a while. The fan works through that brief moment when Protection is displayed. protection displayed and shuts off. speakers are ok. purchased unit three days ago. wire connecton is ok. The stand by button blinks. i pressed the stop button for 5 seconds to stop the blinking, put the power back on, results are still the same, displaying protection and then the unit shuts down. I have the Samsung ht-x30 shutting down on protection. Initially 6 wks ago on occasions switch off without any apparent reason. it became more frequent shutting down on protection and then fan check. took it in for repair and new fan installed. brought it home and still shut off on protection. Took it back in to the repairer without the speakers and it would not do it for him so he believed it had something to do with a faulty speaker, gave him the speakers and still wouldn't shut of on him. brought it home and it lasted about an hour. I work for the electricity distributor and am aware of some voltage issues on the feeder that I live and had a recorder record over a four day period. Had fluctuations between 233V-256V which is slightly outside the allow-ables. The voltage situation has been there since I had purchased the unit. However I took the unit where there are different feeders and different power generation and the unit still shut down. It is becoming obvious that over time the circuitry breaks down. and becomes susceptible to overheating. Whilst the unit is sitting outside the shelf of the tv stand it will run for more extended periods, as was the case when it was at the repair shop. armed with some evidence from this forum I may get some where with the repairer. I have today reversed the fan and hope this resolves the problem. It is however sitting outside the shelf at this point in time. As the unit heats up the more frequent it shuts down. It has been running for about an hour now without shutting off. There was no evidence of capacitor burn out with my unit. Hope this helps.
The solution is get rid of it fast , i had a samsung dvd player that did that then it caught on fire , pretty scary,lucky i was there when it started to smoke up
Your HT problem can be different from mine, but still there is a chance of the same kind of failure. In my case one of the output filter capacitors got broken - it had a crack on its body. Replacement of the capacitor fixed the shutdown on protection. In principal the caps can fail without any visible indication and it would be very difficult to guess what is wrong without deep studying of the system.
