    Welcome to our forums.

    Generally, the PS on an iMac is fairly durable. Can you hear or see anything at all when you start it up? Fans? Backlight? Without a schematic it would be difficult to do any measuring of voltages off the PS. Your best bet might be to buy a PS for your iMac off eBay and swap it out.
