Thank you for the reply Frank.
The issue you're having is due to the laser lens being either contaminated (dirty), or faulty (scratched or mis-aligned).
You can try several methods of cleaning the laser lens to see if it helps clear up the problem. The first is to purchase a CD/DVD laser lens cleaner disc, and run it through the system several times. They are available at Wal-Mart, Staples, Radio Shack or Best Buy for around $10. They have brushes that remove the dust from the laser lens in the player.
Next I would try purchasing a can of compressed air (available at Staples, Radio Shack or even Wal-Mart). Place the spray tip of the air can in the disc slot and spray liberally to remove any excess dust or dirt.
If the CD player is still not reading discs, then the lens or transport mechanism is faulty and would need to be replaced.
In this case you can use the link below to locate a Tech in your area, but keep in mind it may not be cost effective, or practical to repair this unit- as repairs of this type are often in the $150 range.
