You can be calm, we will heal the situation.
You will be able to use a printer
However, your case is very peculiar.
And it doesn't give me peace of mind.
Tell me if you are sure that you didn't make any mistake during the assembly.
In the meantime I will prepare for you a description of how to make a small modification.

I'll also ask you to post a photo with a view of how you've connected all the wires, not just the power supply.

The weird thing is as I mentioned in December. I used to be able to connect USB and Power, I was updating the firmware with the EasyPrinter 3D Desktop App and suddenly the Power Outage began since then.(As seen in the video)
I‘m fairly certain that I‘ve wired everything correctly to Rev A+. However I‘ll still post some pictures.

I‘ll gladly try anything!

Just posted some pics, if it‘s not visible enough, I‘ll post a a new one with description.

I am still interested in various things:
- do you have differential current protection in your home installation?
- whether you connect your computer and printer to the same electrical outlet,
- whether your electrical installation is based on three wires (phase, zero, PE).
By the way.
In the electrical system of the controller it is very important that the GND potential has no connection to the protective ground of the electrical power line (PE).

I also have a request to do one experiment.
It will be a bit of work.
I will ask you to remove the controller board.
Place it on the table in a safe place,
connect only the power supply and the operator panel (LCD module).
Switch on the power supply, in both variants as you did on your movie.

- I don‘t know, sorry
- Tried same and seperate, both result the same way
- I don‘t know, sorry
How can I tell if the GND potential has no connection to protective guard? (Sorry if I‘m frustrating)

Everything is ok, don't worry.
You aren't frustrating.

The easiest way to do this is with a multimeter with a cable continuity test function.
I expect that everything will be correct, otherwise the light would go out earlier. Immediately after switching on the printer power supply.
I'm also interested in whether your computer has an active USB power function even when it's turned off.

Just USB + LCD

Pluggedin USB in PC while it was off, LCD did not light up.
