How to troubleshoot led outage.

I've seen a number of posts regarding led issues. Is there a troubleshooting wiki covering generic steps to follow?

Can you be a bit more specific?
What issues are you concerned about?

I personally have an led out and would like to trace out the circuit.

You're lucky. The full schematic is available. Assuming that the LED
is good, the question is why the LED is not showing activity. The
answer to that one lies in what's controlling the pin.

Therein lies a software issue that I'm unable to help with in this
context.

Solved the software issue which raises another matter. My laptop was purposely not connected to the internet. I finally got fed up and connected an Ethernet cable router to my laptop and plugged back in my board and all the pretty lights blinked and did their thing. So, some more reading is ahead as to why I need to connect to the internet to do anything with the board? I’m paranoid now.
