Radio plays for short time and shuts off ive tride every thing
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.
