7. If the logic board has bulged or vented capacitors, remove and inspect the power
supply. Note: Affected power supplies are rated for 100-127VAC and are known as
non-PFC power supplies. These power supplies were placed into iMac G5 systems
destined for the US, Canada, and Japan.
8. Turn over the power supply to view the label. Affected power supplies have:
• an Apple part number of 614-0293, 614-0296 (as shown below)
• an AC Input of 100-127V, 50-60Hz (listed below the 614-xxxx part number)
Note: A power supply failure may leave a visible residue on the rear cover, logic board,
and the chassis. The residue does not affect the operation of the iMac G5 and can be left
in place. If desired, the residue on the rear cover can usually be removed using a lightly
dampened disposable cloth. Be sure to thoroughly dry the rear cover before reinstalling it.
9. If the power supply fits this description, replace the power supply as well. Proceed to
the next topic, Special CompTIA Codes, for repair coverage information.
Note: Effective today, these power supply replacements will be excluded from
Service Excellence measurement (in applicable regions). In addition, all first-
generation iMac G5 power supplies are no longer available as Do-It-Yourself (DIY)
parts.
Warning: Use caution when handling failed electronic components, and make sure
to wash your hands afterwards.
