RCA HVTV with buildin DVD player

I have a RCA television with a buildin DVD player.
Lately, when I load a DVD into the slot and press play, it puts an on screen message that there is no disc in the player and it will not let me play the dvd. I have to keep taking out the dvd and replacing it in the slot until in plays the dvd. I have tried turning the power off completly and shutting down to reset and sometimes this helps? Is there anything else I can try to solve this problem?
