Piet, judging on your name you’re most likely Dutch.
If you need any assistance in Dutch where to find what perhaps I can help you out since I’m Dutch as well.
Feel free to message me.
I had the same problem today. It was able to give the red light but nothing else. It actually was getting on the network via wifi with some weird device name but would not respond to ssh. I measured the voltage from the power adapter and it was giving me 5.1V, but when I measured the amps, it was something like 0.3A instead of 2.0A, so the power supply was the thing to fix.
I cut off the power cable to get the plug and then cut a spare USB cable so you have an A plug for the other end and then soldered the two. Sure, A to A cable achieves the same result but I did not have one so I had to use the stuff I had. That is in the case that you are somehow acquainted with the soldering iron
Nothing wrong with that. But it just proves that the Vero in that moment only used 0.3A. Surely the 2A is just max doesn’t mean that the Vero always uses that. So while I don’t say that the power supply isn’t the issue here your test doesn’t prove that the power supply can not provide the full 2A.
Idling, it should not take much current, and it should be consuming very little compared to when it is outputting video, so the amperage in my case did not mean anything. The thing that it was not outputting any video and was not able to get on the network properly and red let were on could be the cause of different things. So I was just “lucky” that it was the power supply fault, or a low hanging fruit.
