I have a Imac with a bad analog board,here can one be found.

if the machine is still under warranty, take it into a certified apple tech and the part and repair should be free. if you're machine isn't under warranty, you probably still want to do this because 1) i don't think you can just buy apple parts yourself and 2) pulling the board out yourself and installing the new part (which you probably can't buy) is too much of a hassle.

I agree. Apple's new service strategy is to mail all defective computers to Apple itself for service. I seriously doubt that you could get a board from Apple, although you might find one on eBay. Just be sure your data's backed up before you send your machine to Apple...
