Once display is fully unglued from the frame, carefully lift it up and locate the display connector.

Using the same small plastic tool, carefully remove the yellow tape off the connector.

Now carefully undo the black connector lock by lifting it up in the direction of the red arrow.

Do not pry on the gray part of the connector.

Lastly slide the display cable off the connector. It should easily slide off, if not make sure the black lock is fully unlatched.
