Can anyone tell me if it's a board failure, corrupted microSD, failed PSU, anything else?
To answer my own question, I found another power supply and was able to get the board going again, so without being 100% scientific about it, it looks like the power supply failed. Not being certain of the condition of the microSD card, I then replaced that as well. Hope this helps someone in the future!

Glad that you have discovered is power supply issue. I just plan to respond back the blink cause by power supply enter and release from self-protection mode.
