Recently I have had three iMac G5s 20-inch with 1.8Ghz processors within our workgroup fail to power up or display images properly. We originally purchased 15 iMacs during the period of August 31, 2004 – May 3, 2005. These three just outside of their three-year AppleCare Warranty are no longer eligible for free repairs by Apple Computer.
The program launched in August 2005 by Apple Computer covered a known video and/or power problem related to a component glitch on the motherboard of first-generation iMac G5s. At the time Apple commented that the affected systems have serial numbers falling within one of these 4 five-digit ranges: CK435-CK522, QP435-QP522, W8435-W8522 and YD435-YD522. One has to note that Apple leaves the 2.0 GHz iMac out of its program description. The Serial number is located underneath the foot of your iMac toward the front.
Further details are posted on Apple’s Website.
Apple’s website states that “If your iMac G5 is not covered under warranty or an extended service agreement, such as the AppleCare Protection Plan, repairs for other issues will be made at your expense if you request that they be made.”
Given that these iMacs fall outside of the program’s period, and from what I was able to determine, what caused these issues is simply a bad graphics card or a faulty power supply. I am intending to cannibalize two of the iMacs that have different problems with and try to piece together one good one!
