820-2915-B - Green light no boot (no 5V)

No doubt. I'll start over and see what I can find.
I did find a bad R7261 pin side was broken off. weird. I'm not sure if that was an original problem or the result of my shorting out the other resisters.

I measured at those resistors because they were ones that show up when searching for PPBUS_G3H. How do I determine the best or most likey places to check buses
 
No boot and no Green light.
One wire has 3.42v at u6900 pins 1,4 and 5
u6900 has 3.42v at pins 1,2,4 and 5.

3.42v at pin 14 u7000 so I have SMC BC ACOK.

To start your SMC and/or ISL6259 is bad at this point you killed that. I advice against putting effort in this board. It'll be back with a dead GPU in a few months anyway.
