LED not working on 3GB variant
The LED is a common cathode unit. The R/G/B elements are each connected between a GPIO pin and ground.
Page 11 https://files.pine64.org/doc/PinePhone/P...ematic.pdf

All the different OS I've tried at least blink the LED in some color during boot. The factory test image will also cycle through the colors.
Since you don't get any output, the LED is probably damaged or missing.

The LED is the tiny white SMT device to the left of the headphone jack and proximity sensor. https://pine64.com/wp-content/uploads/20...oard-2.jpg
