Topic: ADI-2 DAC - Power light white, but not working

Hi all,
I've just purchased a used ADI-2 DAC FS and it's not working.
I plug the power and the power light turns red, then when I press the power button its light turns white but nothing happens on the display. See image below.

Before I return it, is there something that I could try?

Total Reset as mentioned in the manual. But display off usually means something broken inside.

Have a look at the power supply that was delivered with ADI-2.
Is it the original, or a replacement one that doesn‘t have enough power?
This can cause the described symptom too.

To identify:
The original PSU is marked as 12 V / 2 A.
It has a turn-lock connector on the ADI-2 side.

Looks like this:

I tried total reset as in the manual and nothing changes.
Yes the  power supply is the one in the picture, 12 V, 24W, 2A with the turn-lock connector.

And back it goes - I suppose!

Can you test another 12V power supply?
