The same problem occured with my SL-PG570A - I put the disc in but the display reads 'no disc'. I don't know what the problem is, but I was about to open up the case so I moved the unit and when I turned it back on it started working again! Maybe something got stuck? It's working now which is good cuz I love my Technics CD player.

S, I had exactly the same problem on commercial CDs, and just fixed it. Went to Sony's site (useless), but then found a great and very detailed site on disc readers, http://www.repairfaq.org/sam/cdfaq.htm#cdgicl
Bottom line, believe it or not, was that all I had to do was clean the laser lens!!! I used a drop of gin (probably not ideal, but I didn't have any isopropyl handy) on a cotton wool bud and carefully wiped the lens, and hey presto, it worked immediately on all CDs I've tried! Note that it didn't *look* dirty, but I figured I had nothing to lose. I wish all fixes were that easy!!
