What’s New
October 2007
Updated Logic Board replacement procedure. A “caution” was added to notify service
providers not to twist, flex, or bend the iMac G5 logic as you install to board into the
chassis. Flexing the board may jeopardize the thermal interface between the heatsink and
the processor. Refer to the iMac logic board inbox notice 073-1158 for additional
information.
July 2006
A diecut piece of microfoam (922-7671) is included with all replacement optical drives and
display bezels. It should be installed in between the disc drive and the display bezel to
prevent optical media from ejecting out of the system and dropping to the desktop. Only
one diecut of microfoam should be used per system. Refer to the replacement procedures
in Take Apart for either the optical drive, display bezel, or microfoam shim for more
information.
Display/Bezel Assembly Elimination
Effective July 24, 2006, the Display and Bezel assembly module will no longer be available
as a single service part for the iMac G5 (17- and 20-inch models). The Display and Bezel
are now available as two separate service parts (see below) to simplify inventory and
reduce repair costs.
