Hi
Here is a link to the service manual for your tablet. It details the pre requisites and then the procedure for removing the LCD display.
https://www.manualslib.com/manual/950790/Lenovo-Yoga-Tablet-2-Pro.html#manual, scroll to p.44 (it is actually p.40 in the document but shows as p.44 in the page numbering link system
Also go to p.117 (p.113, as above for their numbering system) to find the part number for the screen. Use this number to search online for replacement part suppliers.
