Well, probably not the right place if there is one. CD player in my car does not play through one channel. It tries but rarely. I figure there is something wrong with the head. It does play in stereo with cassettes or radio. So it has to be the CD player itself. Has anyone ever taken one of these apart and made adjustments ? Its like nobody fixes electronic equipment these days, everything is throw away but this seems like a simple problem and its not a bad unit, plus still plays my cassettes without trying to eat them.
