Stereosistema 2.1

Models don't know,but until yesterday worked steadily.I'm always Rubaiyat in the toy,and there was a crash and the sound began to hum as Maritime trombone.When restarting from the logo again, we have the trombone and not off Chaz tumbler he didn't leave,the wait to cut down the main switch on the Saba.The question is simple:what happened and is there any method to eliminate this roar dinosaur,because the stereos are so expensive nowadays.
