You've

shorted something and burn marks should be evident (but might be where you can't readily see them behind or on the back of a part)

If you don't find and repair the short and continue to power the machine you'll further damage it, or start a fire.

Going back doesn't seem to be an answer... You'll have to go over the machine piece by piece until you locate the problem, perhaps dismantling farther than you did before.

If this answer was helpful please remember to mark it accepted.

Good Luck,

The first thing that usually goes on this machine is the power supply. I fixed one like it today. Look for burn marks right where the cable runs out to the logic board plug. The power supply is gray and at the bottom and has the power cord input on it. To make sure, plug it in and check the diagnostic lights at the center of the logic board. Press the lower CUDA button (to the left of the lights) to restart the machine. If the second LED lights up then look to the logic board.
