Often the disc sticks because of a warped disc or some foreign object got inside from child or some one messing with the unit. In the worst cases it has required the unit to be removed the covers taken off and reaching into the mechanism to release it. The releasing may reveal something stuck, bent or out of place. Or, it could be just wear and tear that has caused too much movement for one of the moving parts.
Audio Design Engineer; systems, loudspeakers, cd/dvd players, etc. I am knowledgeable in all high end audio equipment and installations. MAKE SURE YOU GIVE A MAKE AND MODEL NUMBER AND CAR IF IT IS AN AUTO QUESTION. Note: I am getting some who ask good questions that take a lot of time to research but then the questioner fails to read the answer. Please don't ask questions unless you are seriously looking for an answer. If you find an answer to your question otherwise then let me know with your reply. Thank you.
