If cleaning the lens does not solve the problem then I make sure the laser is working. I normally clean the lens just in case there is dust on it obstructing the laser path. I normally do two things when this happens. If the laser has failed, then it will not be able to detect a CD and therefore the error message appears. This is the time when it is looking for a disc. This can be infuriating because you can see that there is a disc, however, the CD / DVD player cannot.Įvery time the tray closes, the laser beam fires two long bursts of laser light, and the focusing platform moves up and down attempting to focus the beam. If you are getting a NO DISC error on a CD / DVD player, then chances are the laser has failed.Ī typical symptom is you insert a disc in the player and after a while the CD tray opens again with the message referring to no disc being in the system.
