Ultra 45 won't boot

I have a new Ultra 45 that will not boot up. Once you hid the power button the green light comes on for about 5 seconds then the box powers off. I have looked through the entire service manual to try and figure out what has failed. Any ideas?

Sounds like something you'll have to open a Sun Warranty case for. Bad mobo, PS, RAM, processor, could be almost anything...
