RE: Lens Cleaning CDs

I open up the CD player and use an alcohol soaked cotton swab ( q-tip) to wipe the lens clean. You can find them in any pharmacists shelf, or ask your doctor for a spare.

Sony CD players (and others of similar design) suffer from their magnetic chuck. The continuous slamming of the chuck against the CD turntable eventually drives the TT a bit lower and out of focus for the laser lens assembly. Careful examination of the CD TT shows that it is a plastic piece press fitted to the motor spindle. Gently prying the TT upward just a wee bit normally works well to insure the disc is in range of the focus motor's range.

Of course being a 15 minute repair, most stations would rather charge you significantly more by changing out the transport. Sony Laser mechanisms have been one the longest lasting I have ever worked upon. HK used them and I have units in the field for close to 20 years now.

of course, YMMV
