I have a JVC UX-MD9000R Micro Component System which has been well taken care of. However, now when I put in any MD disc, 'TOC Reading' is displayed, but no flashing (= reading?) occurs. The disc is then ejected and the display now reads 'No Disc'. I can't try a MD Cleaner since the above happens. I have tried alcohol + cotton bud but insides are as clean as they come. Might this be a laser fault? Any suggestions welcome Many thanks
