Radio keeps displaying reading error please eject and check disk

There's no disc in it. I've tried resetting everything and it still doesn't work. It displays the message on every screen sometimes it will not display and then other times it will. In order to change the station or go to DVD I have to hit the eject button and then it goes right back to that same screen. I am wondering if there's anything else I can do or if I have to get a new radio?
