I have jvc avx44. I have bought it few months ago. It worked very good, but now it started to turn off by it self and at some time it turns on by it self. To tell more exactly: I turn it on, it plays music. After some time avx44 just turn it self off and stays off. After it is off, I can't turn it on, but the light near button on/off is shining. If turns on after a while by it self....... I think u got what I mean and I will wait your answers or more questions if you didn't get everything...
