If the indication says" not ready " it means that the disc is not reading the data present on it . It is possible that the disc is not scanned by the optical head to be ready to play.
So it is possible that the optical head is defective or weak, please try to clean the optical eye with ear bud very softly or use a disc cleaner.
If there is no result the head can be faulty.
If the set was not used for long time please keep it powered ON.
Also the processing section/main board can be a suspect.
