simple fix for this problem. take the cover off and you will see a plastic cover above the disk tray. it will have a tiny screw, remove the screw and then you can gently pop off the cover. under this you will see a clear plastic shield with a small eye under it...this clear shield is the eye..dont take this apart, just dab some alcohol or window cleaner on tissue or qtip and gently wipe the plastic shield a few times. thats it. do this every time you get the no disc error and you will never have to replace your player.

have you tried both DVD and AudioCD disks?
and made sure they are originals.
if it will play one but not the other it could be the laser has
worn out. all i can suggest is using a lense cleaner.
