Hi,
Here is a link to the [https://cdn.cnetcontent.com/7e/29/7e293817-b463-4157-9cb3-2da3c416c84b.pdf|service manual] for your Yoga 3 14.
Scroll to p.56 to view the necessary pre-requisite steps and then the procedure to remove the LCD module.
Scroll to p.64 to find the part number for the LCD module. (5D10H35588).
Search online using the part number ''only'' in the search box of your browser, to find suppliers of the part.
Hopefully this is of some help.
