I have noticed over the past year many requests for replacement iMac G5 motherboards on the swap group. I found myself in the same boat when I inherited 2 2006 G5 iMacs one 17 inch 2.0 ghz and one 20 inch 2.0 ghz. A further investigation I discovered a site that does replacement capacitor service on motherboards. His primary is replacement on non Macintosh motherboards but he will do the replacement on Mac's as well. The catch for Mac's is that he has no way to test the motherboard for Mac's when he is finished so you must be confident that your motherboard failure is due to blown or swollen Capacitors. The Site for much more information is ( www.badcaps.net ) The site tells you what caused the problems with the capacitors and other data. Also if you are interested in having him repair your mobo there is a form to fill out at the site. The cost at the time I had the repair done (Aug 2011) was $85.00/mobo plus $20.00 return shipping. This guy also sells Capacitor kits for the do it your self person. Bear in mind that Apple mobo's are multilayer boards and the components are soldered using lead free solder. This solder requires a hotter iron temperature for soldering than lead based solder and using lead based solder to replace the caps is not recommended.
Another site ( www.jimwarholic.com/.2008/07/how-to-repair-apple-imac-g5.php ) gives you instructions for the do it your self. This site page also shows you which Capacitors ( @30 ) need to be replaced. For disassembly instructions ( www.ifixit.com ) has downloadable pdf Apple take apart instructions. This is a great service, both of my mobo's were repaired in about 3 weeks (time will vary depending on his backlog). Upon return I reinstalled the repaired mobo's and both computers booted and are working as per new. Some Indications of failed capacitors will be failure to completely boot up, Spinning beachball on a booted computer when you attempt do preform some function, lots of system crashes and kernal panics. So if you have any or all of these indications check your motherboard visually for swollen or blown capacitors.
