Here's the 96 page User's Manual for downloading: http://www.pdfoo.com/mobilephones/251-83...

These machines have been plagued with bad capacitors. Inspect the 25 caps on the board for corrosion and/or bulging. The power supplies area also frequent problems, look for a burned spot right where the cables go in.

iFixit has lots of threads on the problems of this machine. In the search box at the upper left hand corner just type in "bulging" to find many of them.

Here's a very technical thread to some of the problems: http://www.badcaps.net/forum/showthread....

Thanks for your reply. The unit is a iMac G5 17" Model A 1058. I checked the capacitors and they looked OK. The two green lights on the board functioned OK. The Hard Drive eventually kicked in but was sounding extremely quiet, there was no power to the cooling fans. Some power was getting through to the HD but not to the rest of unit. Could bad HD affect function of boot sequence ?
