Jetson Xavier NX developer kit turns on but doesn't give dsiplay


I got a nvidia Jetson Xavier NX development kit. It was completely working fine, suddenly, one day I turned it on and it didn’t display anything on the screen. It didn’t turn on the keybord nor the mouse, but the led on the board was green.

I read many forums and i got the log with serial console which is the following.

I’ve tried flashing different jetpack versions in differents SD cards and still got the same log.

I don’t know what is the problem. Can someone please help me to figure this out?

Looks like the display driver is failing. Is this natively an HDMI monitor, or does it have adapters? What happens if you boot without the monitor, and then plug in the monitor? Be sure to watch serial console and see if there is a kernel panic prior to plugging in the monitor. Even if there is, see if it repeats with an HDMI unplug/replug.

Yes it is a natively HDMI monitor. I also tried with a DisplayPort monitor and got the same result. I tried plugging the monitor after it turned on, but nothing happened.

Now I’ve tried booting with Jetpack 4.6.3 and I get this outcome.

I don’t know what to do because the keybord and the mouse don’t turn on. I think the jetson isn’t recognising them. Do you know why this is happening? And what can I do?
