I am a car audio newb. A few days ago my deck, Kenwood KDC-x815, stopped turning on, when i attach the faceplate it stays blank for about 30 seconds, then slides down like its going to eject a cd, or i am supposed to take it off. I assume the latter....however it plays no music and i have no idea whats wrong with it as i cant find the manual, nor can i find one online. Please help. Thanks.
