Maybe the 3.3 volt reg has been knocked out. By a bad feedback loop ? - maybe
You could check all your 0 ohm resistors. See if they are Ok. They are clearly marked.
You can also check your fuse blocks and thermistors.
Find out if you have 5 volt standby is still present
good luck

1) 3,3 volt into SPI is ok, the JR PROGRAMMER IS START
2) The resistor value is : -8 ohm about
3) Where is the fuse and thermistors?
4) The 5 volt into J2C3 PIN n°13 is ok
I've found the motivation, i connect the GND into wrong point!

Sorry for double post, but i have a breaking news:
i put a finger into pin at top left of the nand and the xbox start O_O but i remove the cable of power and put in again the xbox have the problem (no power on) if i put the finger in the pin, the xbox is start O_O

Try flowing fresh solder to that side of the Nand connection. Maybe a pin or two broke loose from the pads.
Use flux and do clean work. Make sure you leave no bridges. Inspect it with a magnifying glass

I don't press the pin, the console work though take off the finger!

Yes! this doesn't make sense!!! but now have the other problem, with finger now write, erase and read... but not start! if i plug in the power into xbox now the JR PROGRAMMER blinking the green led (before stay on!!)
