Moreover, if that did not fail, then the laser surely would. Most of those units used cheap motors where the brushes wore out within a few years. It would be very surprising to find a player still working from that era. Laser diodes do not last forever, especially on the early players manufactured in the 1980s. These two components are in constant use and wear out the most.

If there is no red light, then the laser has failed.Д«ack in the 1990s, I used to fix many of these and it was always either the spindle motor or the laser that failed. It is usually bright enough and visible from the other side of the paper. A piece of paper the size of a standard CD within the tray can also help, because when the tray closes, one can see the diffused red light on the paper. The laser light is bright enough that one can see the diffused red light from a distance obliquely. Obviously one should never look directly into the laser unit, you would have to be plain stupid if you did that. 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.Д®very 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.ДЄ 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.
