The digitizer connector has probaly become dislodged slightly I have fixed many by opening the back and reseating the digitgizer cable. This is much more common when someone has removed the emi shield from the back of the board.

Yup, you just need the digitizer. The LCD and digi come as one part so it should be an easy fix. If your not sure how to see youtube or get a pro to do it. You can buy the part here on this site or try other sites like;
