how can i fix my TECHNIKA built in dvd player?

does anybody know how to fix the built in dvd player on a technika 19" lcd with built in freeview and dvd. not had the tv long and the dvd player has just stopped working, you put a disc in and it says reading but then says there is no dics. tried using a cleaner but thats a disc and it wont read that either. i have had a look on internet and noticed its quite a common fault but not seen a solution for it anywhere.
