BOATDOCTOR

i picked up my car from the body shop yesterday and im sure its a coincidence but now my dvd player isnt working! when i insert a disc it goes in fine but starts making a grinding sound and wont recognize that a disc is in... i think its the motor inside? but is inserts and ejects fine. im going on a long drive this weekend with two young kids and really want the dvd to work! does anyone know what this problem is and if its fixable?
