Power Button light will not turn on, how to troubleshoot

I have an Evolve Carbon GT and the power button blue light will not turn on at all (not even a blick/blip or flash). In addition, the board will not pair with remote (just in case the everything is fine except the blue light doesn't come on anymore).

• Whether plugged in or not plugged in, blue light will not come on.
• I have tried unplugging the battery (both connectors from the motor controller board) and leaving set for at least 20 seconds to flush power
• I have left the power button on for a while
• I have pressed the power button on and off many times
• I can successfully charge the battery (multimeter measures the battery at 40volts)
• I have not gotten it wet
• I might have charged it with power button pressed in, not sure
• I have not gotten it wet recently (I did like a year ago but let it tried and did not have an issue after that)
• The board is not under warranty

How can I troubleshoot this issue further? Can I use a multimeter to debug and isolate the issue? Any guidance would be appreciated.

 

Did you ever find a solution? I have same issue out of the box.
