Yes. works without connecting to the usb
when with a bit of luck it is only the mosfet (TR7) for the PS_ON pin you need to replace. picture would still be helpfull.
(although TR7 will not have any effect on a faulty PanelDue)
Thank you -

jumper ext_5v I am not set
that explains why the rest of the board is okay, there is no connection from the indicated pin and the rest of the board with out ext_5v jumper.
it doesn't explain why PS_ON pin died; maybe you put 12v on the PS_ON pin? (the middle of the three)
regardless of where you put 12v on that connector it doesn't offer a clear explanation as to why the paneldue failed, if you can include a picture of the wiring (power off!!) it may help diagnose.

I have already removed the excessI'll draw it now

I cannot see how connecting 12v to that pin with the ext_5v jumper removed should cause any problem at all, its effectively disconnected.
could there be some loose strands or something on the connections causing a short?
-
@bearer
Maybe due to the fact that I pressed the power button? -
a short between PS_ON and ground would explain why that mosfet may have failed. but it has no connection to a failed paneldue so there is something missing from the equation.

This of course will not help, but when turned on, the entire Board (LEDs) and screen flashed -
Unless well lit and focused pictures of the boards have any clues I don't think I have more to add I'm affraid.
Replacing TR7 (tiny mosfed between the Vin terminal and the always on fan) will likely fix the PS_ON problem, but no idea why or what caused the paneldue issue.

Thank you again.
