I have the Technics 60+1 CD CHANGER, SL-MC59. I keep getting the message NO DISC, when there is a disc. Not recognizing the read. If best bet is to clean the laser. My next question is how. Ive put a Laser cleaning disc in there, but no read no clean. On my last post I mentioned that I cleaned the laser but the laser is inside so no way of cleaning yet. What I meant was Laser cleaning disc.
