X360 Slim Corona Not Start Only Beep

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!

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!
