Banana PI M5 don't boot

Good morning,

I recently purchased a Banana Pi BPI-M5 Amlogic S905X3.

I can’t start / boot it, I have connected it to HDMI and a keyboard and mouse.

I would like to specify that this is the first time I have purchased such a device.

I tried several micro SD cards, HDMI cables, I also installed many images, going from debian, armbian to ubuntu.

However nothing happens.

I don’t think the problem is with the power supply.

It is a USB Type C power supply of 15.3 Watts.

I’m a bit confused and a total beginner, I hope I didn’t do anything wrong.

Thanks for your help ^^
