My Kenwood Receiver is all messed up and i dont know what to do. When i turn my truck on, it turns on, but there is nothing on the faceplate, no text or anything. But there is sound. I cant touch any of the buttons on the faceplate, nothing works. only on the contoller. But only the presets and cd buttons. i cant change no volume or anything. I cant live too much longer without my stereo, please help me ASAP!!!
