Logic Board - Model A00
Logic Board Component Inspection- Later Model A00
During the logic board removal procedure it is necessary to visually inspect the logic board modules and
components for burns, cracks, discolorations, or other indications of damage. If damage is found, use
Figure 125 and the Logic Board Component Inspection Reference to identify the damaged driver circuit.
Replace the cable and component related to the damaged circuit in addition to the logic board. For example, if
you discovered a burned area around the U38 module, you would replace the AFTA motor and the AFTA
cable, as well as the logic board.
