Jetson Xavier NX failed to boot

Hello, my Jetson Xavier NX couldn’t boot after I normally shut it down a week a ago. Now whenever I power on my board, the green LED next to the Micro-USB connector does light and so does the LED for the ethernet port. However, there is no signal to my hdmi monitor. In addition, USB mouse and keyboard are not powered by the board at all. Since there is no display presented, I have no idea what goes wrong during the booting process. Can anyone please help me with this situation?

Really thanks for helping!!


When monitor is not working, we always check the log from serial console.

But if your LED does not light up, it feels like a hardware defect.
