Power light isn't turning ON, display is also not coming

[bilal4]

Hi,
I have a Jetson Xavier NX Developer Kit, it was working fine with Jetpack 5, in the evening it was working fine, but the next day when I tried to Turn it ON, it was not showing the display, the power light was also not turning ON.

Physically the device is not damaged.
I checked the voltage with Digital Multimeter, and it shows the correct voltages (3V on 3V Pins & 5V on 5V Pins).
Lights on the ethernet port are also not turning ON.

I checked with a local technician, and he says this might be a problem with the jetson’s firmware (because the hardware is fine).

I am using the original charger (the image is attached at the end) that came with my Jetson.

Any help will be appreciated in this regard.

Hi,

please see if you are still able to login via UART.
Connect a TTL-USB cable to the J14 header on your board, and run this command on your host PC:

sudo picocom -b 115200 /dev/ttyUSB0

If nothing shows up, or it gets stuck during the booting process, please re-flash it.
