Hi
There is no sound when I play the CD in my boom box, the radio works fine but not the CD. I noticed that the CD disk spins very fast and then shows the "ERR" in the litthe window where the number of song appears. This is the third CD player that behaves this way, why? I am not a kid and treat the playes well. I repair many things (electric, mechanic, etc) can you tell me how to repair these player? My last player is a "TRUTECH" Model T300-B, mannufactured on Nov, 2006.

Thank you
Pat

Pat, 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!!
