Jetson nano screen's switch off without reason

Hello,
My jetson nano’s screen is switching off apparently without reason. I can’t use it, i haven’t ip adress for ssh, and if I connect computer or mouse, or just when I try to turn it on, the screen switch off (no input signal). The green led turn off too, but the jetson is powered because my mouse rbg’s are lighting. I have tryied all my power supply (5v 2a) but that change nothings. Anyone have this problem or a solution?

As other issues, please try to dump the log from serial console and we could debug.

I took other power supply to a friend, always 5v 2a, and It’s working now. It’s seem jetson nano compatible with just a few power supply whether or not they meet expected standards
