@OscarGM From those pictures, with 24V input there's no 5V or 3.3V LEDs, they only light up with USB power. It also looks like jumpers are on 'Internal 5V enable' and '5V->SBC' correctly. I can only assume the 5V regulator is dead, but can't see any damage to it. @dc42 to confirm?

@OscarGM The 5V regulator is the 8-pin chip by the corner of the inductor marked 6R8. Yours (bottom right):

I can't see anything obviously wrong. @dc42 ?

Looking closer the part to the left of it isn't level, but are you sure about that being the 5V regulator? (Schematic says U5 and tiny 16 pin QFN chip) (Wrong board)

@droftarts I don't know if this can clarify something https://www.dropbox.com/s/cxmiagz20t1ytjx/5V%20Regulator%20Duet%203.jpg?dl=0)

@OscarGM, thanks for your patience. I approve a warranty replacement for your Duet 3 main board,

[OscarGM]

@dc42 thank you.
Do I have to do something about the process?

[droftarts]

@OscarGM I think you've already emailed us, I'll sort it out.

I did that too! I looked at the 3HC schematic by mistake. It made me doubt @dc42 ... but only for a minute or two!
