vickenk: Thank you very much for joining the Intel® NUC communities.
In regard to your question, yes, the unit could be bricked or it might have a hardware failure.
Do you have the option to use a different power adapter and test it on different outlets?
We can also try a BIOS recovery to the latest version of the NUC, 0048:
If after trying the steps above the issue persists, then, the next thing to do will be to replace the NUC or the power adapter. Remember the Intel warranty is for 3 years. Please get in contact directly with Intel if you are interested in this option:
