How to Troubleshoot a CD Player

These simple techniques will help you troubleshoot a CD player that's giving you trouble.


  • Step 1: Check the power supply Make sure the player is plugged in to a working electrical outlet and the power cord is undamaged and connected to the unit. Replace old batteries and clean corroded battery contacts.
  • Step 2: Check connections to the amplifier Check the cords connecting the player to the amplifier. Clean contacts with cleaner or alcohol and a cotton cloth to eliminate static.
  • Step 3: Check transport locking screw See if the player's transport locking screw is engaged. If it is, loosen it.
  • Step 4: Test with a commercial CD Use a prerecorded CD to test the unit, not a CD-ROM created on a computer. Some CD players are not compatible with home-burned CDs.
  • TIP: Be sure to load the CD correctly. Nearly all CDs should be loaded with the label side up.
  • Step 5: Clean the CD Clean the CD if it skips or the player can't read it. Use a clean lint-free cotton cloth and make sure the CD is not scratched.
  • Step 6: Clean the lens Use a lens-cleaning CD in the player. If you can access the lens without opening the case, clean it with a cotton swab and lens cleaner.
  • TIP: If you open the case you will void the warranty. If your player is under warranty, return it to the manufacturer for repair.
  • Step 7: Check the belt on the CD drawer Check the belt on the loading drawer if the drawer does not open and close correctly. Refer to the owner's manual and remove and clean the belt with alcohol, or replace it if worn.
  • FACT: Thomas Edison was not the first to record sound, but his invention, the phonograph, was the first machine that could play back recorded sound.
