To Next PageTo Next PageWhy is my Sharp Stereo System CD skipping tracks or not reading the TOC?
Track skipping or failure to read the Table of Contents (TOC) on your Sharp Stereo System CD player may be due to dust or foreign matter on the laser pickup lens. Ensure the lens is clean. If it's dirty, clean it carefully.
What to do if the CD does not function on my Sharp Stereo System?
If the CD on your Sharp Stereo System is not functioning, the objective lens of the optical pickup might be dirty. Clean the objective lens and then check the playback operation. If the problem persists, remove the cabinet and follow the troubleshooting instructions.
