The problem is most likely the amplifier circuit. It is probably over-heating and the speaker relay is turning off. it is not likely that it can be diagnosed properly on an online forum, since it takes some troubleshooting to be certain of it. Does this system have the amplifier built into the sub-woofer? If I had the model number I could probably give you much better advice, not all home theater systems have the exact same problems. Each different model of every brand have there own unique problems specific to that model number. There are some universal problems, but this is not one of those easy to figure out universal type of problems. I work at an authorized Samsung service center and have experience with repairing these type of systems, so if I were to get the model number I could offer you a better solution. But it is likely that it will need to be serviced to determain the exact problem. A couple of the Samsung home theater systems that have the amplifier in the sub-woofer must have the entire sub-woofer replaced because they do not offer the parts and service data needed to do a component level repair.

One way to determain if the sub-woofer has the amplifier built into it is if all the speaker wires for the sattelite speakers all connect to the sub-woofer.

Sometimes a bad speaker can cause the amp to get hot and shut down, you can check these very easy yourself.

First, while the system is turned off, disconnect one speaker. Any speaker is OK to start with. After one speaker is disconnected, turn on the system and play it at medium volume. If the system stays playing and doesn't turn off the speakers as it did before, the speaker that is disconnected is probably bad. Take it to a service center and get it checked to be certain. Most service centers will do this for free as a courtesy to their customers, it only takes a minute to check.

If the system turns off as it did with all speakers connected, you then need to reconnect that speaker and disconnect one of the other speakers and go thru the proccess again. Make sure to do all of the speaker connecting and disconnecting while the system is turned off.

If you end up disconnecting all the speakers one at a time and the system still shuts off, it could be that the sub-woofer speaker is bad or the amplifier is bad.

If you can give me the model number of your system, it would help.

No Disc


The drive needs repairs, or replacement. Check your warranty you may still have it and in that case you will most likely get free repairs.

I HAVE A LG HT506 DVD PLAYER AND WHEN I PLAY ANY DVD IT PLAYS FOR A SHORT TIME THEN THE PICTURE FREEZES . IF I LEAVE IT FOR A SHORT WHILE IT STARTS PLAYING AGAIN THEN FREEZES ONCE AGAIN CAN YOU HELP...


By your description it sounds like the DVD player needs to be cleaned. You can purchase a CD/DVD cleaner at most places like Walmart, Target, or Radio Shack.

Try cleaning it first. If that doesn't work, it will probably have to be repaired by a professional, if it's not under warranty.

Good luck!

System shuts off after short time period


does all functions play properly during this time?(before shut down), if that is so, it might be loose connections which you can verify by tapping on the unit at various places.

While playing the DVD of Dark Knight on my 5.1 surround system last night, my audio system would simply turn itself off.  It seemed to happen during moments of extreme sound, i.e. explosions, gun shots,...


this is a common problem with this unit the main thing is a low grade capcitor that the manufacturers used which is known to discharge all of its power at once which it recieves a high signal output and tells the unit to shut down the solution is very technical but basiclly you gave to install a higher amp capacitor.

RCA RT2250 consistant shutting off in Satalite mode.


Mine will always just turn off every minute or so after a hard shut down(ex: power outtage). I have to turn it back on and then hold the set button for a few seconds, then it stays on, until i turn it off manually, since the remote won't turn it off.

System unresponsive when modes are switched


Sounds like there may be a glitch in the microprocesor. Make sure when you unplug it that you leave it along for a few days and is there any type of clock or standby batterys in it take them out as well. If that dosent correct the problem your gonna need a service manual to trace the switch pulse to see if the units Switch matrix lines are low or lost because of a faulty micro or a bad componet like a small caps they install on the matrix to keep noise off them. Hard one to call with out seeing unit and analizing unit Good Luck
