							LED Cinema Display (27-inch) Additional Procedures — Retrieving Mechanism 108 2010-11-18
Overview
Without a stand or VESA 
mount installed, the 
mechanism can retract 
inside the unit if an access 
card trips the latch that 
locks the mechanism.
In the rare event that 
retrieving the mechanism 
is necessary, follow this 
procedure. 
Note: You may notice 
small differences in 
appearance between the 
images in this procedure 
and the computer you are 
servicing. Although the 
appearance may differ, the 
steps and sequence are 
the same unless noted.  
Tools
• Access card  
(Apple part #922-7172)
•  Retrieval tool  
(Apple part #922-7849)
•  Scissors to cut access 
card in half
