No powerindication from my P5

Hi

My problem is that my P5 detects 0W when I connect my DAC to one of the outlets and when the other ones are turned off.The DAC is turned on, when I notice this.The graphic shows that a regeneration takes place.There is no problem when I connect my preamp. Then the power indicates a higher level even it is a little low.When both my DAC and Apple TVbox are connected and the other two outlets are turned off, they both show a power of 0W.The sound is better when I connect all my sources and class D amp to the wall.Can my P5 be defective?

Regards

The DAC is probably taking so little juice that there isn’t enough to register on the screen.
