Power problem: not getting 24V

@fcwilt thank you, for your respons. Without the Duet board connected the power supply does output 24V.
When you test it with the power supply connected have you disconnected everything else from the board?

@fcwilt Yes, only the WIFI antenna was connected.

Well that suggests something on the board has failed and is shorting out the power supply - thus not voltage is measured on the board power in pins.
However I don't know the board hardware well enough to know what that might be.
@dc42 would surely know.
Is there anything on the board that looks burnt or swollen?

Not that I can see of.

I don't see anything either.
Well it is possible, though not likely, that the power supply has failed in a way that prevents it from putting out any power under load (when connected to the duet board).
Do you have another power supply you could try?

@asen Tomorrow, I'll try in the lab with an 5A 30V Adjustable DC Power Supply. Should be okay to test with, I think. I'll post my findings/measurements.

Have you tested the fuses for continuity?
Do you notice any components getting hot when VIN is applied?
What LEDs light up when VIN is applied? -
@asen Good news, when plugged to the LAB PSU, the 12V LED lid up. With nothing plugged into it, their is a current draw of 0.1A. I've taken a temporary 24V-6.5A PSU.
ps: Yes, I know the wiring is not adequate, it was just for a quick test. When used with a PSU all my cables are crimped.
To do: Test it with the new PSU, if everything works as intended I'll write it.

@phaedrux Yes, if you're talking about the two big fuses by the VIN port. Both are still good.
Nothing is getting hot. For your last question I kindly refer you to my latest reply on this thread.
thank you -

@fcwilt Yes, just tested with the new PSU. Works again, Thank you for your help. This thread can be marked as solved.
