iMac G5 (20-inch iSight) Take Apart —Logic Board 92
Replacing the Logic Board
Position all the logic board cables out of the way (except for the hard drive cable that 1.
attaches underneath) so the logic board can be placed into the rear housing.
As you lower the board into the rear housing, make sure the memory pull-tabs are lowered 2.
through the access door opening and the screw holes line up with the board..
Note:3. If the replacement logic board doesn’t have the support brackets (shown below)
installed on the heatsink, transfer the brackets from the old board. Replace the two T6 screws
on the top of the brackets and the T7 screws from the side support bracket.
