- 1). Try a different DVD in your player when you get a "no disc" message. The problem might be with a specific disc, rather than your machine, which displays a "no disc" message when it is unable to read the digital information encoded on the DVD. If different DVDs play fine, then the problem is with the original disc; clean the disc with a few drops of rubbing alcohol applied with a clean cloth or camera-lens cleaning paper, which is available at photography stores.
- 2). Clean the DVD player. A "no disc" message is typically caused either by a dirty DVD, which your player is unable to read, or a dirty laser lens in the player itself. Buy a quality lens-cleaning disc, pop it in your player and clean the machine. This typically takes no more than five minutes.
- 3). If you still get that irritating "no disc" message and your DVD player is no longer in warranty, unscrew the back cover and remove it for a more thorough cleaning.
- 4). Hit the eject button to release the DVD tray and look for the laser lens underneath the tray.
- 5). Blast the lens with a burst of compressed air to dislodge any dust or lint that has built up on the lens from continual use.
- 6). Swab the lens gently with a Q-tip dipped in rubbing alcohol. Allow the alcohol to evaporate.
- 7). Replace the cover and try playing another DVD.
