Introduction
Note that the boards and cable connectors inside of the display assembly are extremely delicate, and patience should be exercised when working inside. To get inside the display assembly also requires you to cut away adhesive strips holding the assembly together. To ensure that your new display adheres to the back panel properly, you may want to clean and remove any old adhesive from the device and replace with some fresh adhesive strips. However, all of this can be circumvented by replacing the display assembly as a single unit instead.
If your Lenovo Yoga 900 has a cracked, broken, glitchy, or otherwise problematic display, or if it has lost its touchscreen capabilities, replacing it should return your computer to working condition.
Be sure to unplug and completely turn off your device before you start working.

Step 21
- Gently pry up any of the boards that are missing from your new display with a nylon spudger and put them in the same place on the new display.
- Emphasis on the ‘gently’—we had two of these boards snap or bend significantly while trying to get them off. Be particularly cautious when prying up the yellow-accented webcam board in the center, as the adhesive is quite strong.
- The touch control board on the far left is wired into the digitizer and cannot be removed. Your new display should come with this board already in place.
