OOpppssss.... the most troubling problem of xboxes... you have got fried MOSFETs and maybe some Power Regulators on the board... Which revision board is it?

I'm not exactly sure I'm not at home now but I think it's a falcon or maybe a jasper

hey ... looking to help you with this too

Your power brick - is it OK ?

Don't have much time for explanations right now. Will develop reason later

Things to check: look for bulged Caps, check your standby voltage, could have a dead Mosfet , could have a Power reg that is dying

Check your USB ports for damage. Bent pins won't allow it to power up. Check the solder connections on the power port.

Mosfets - may look alright to the eye. But have to be removed and tested to see if they still work.

Look around for missing components.

And lastly, sometimes the Southbridge chip can play into this. Reflow or reball could correct it. But that is a very last step. The areas mentioned above are more right on the money
