Please check my following suggestions in your nano kit,
1.Did you make sure the J48 jumper is not connected on your nano?
2.Does your SD card have 12 partitions?
if my above suggestions are correct in your board and still facing the issue ,then please connect a jumper across J48 and try to power up the Jetson nano using 5V barrel jack adapter.
If you are still facing the same issue then it could be board failure!
