I have now also:
- Carefully disconnected and reconnected all the components
- Tried a different SD card
- Attempted to plug the micro HDMI to HDMI into a display to see if I can see anything to show up there and I do not.
- Shined a flashlight onto the screen just in case to see if its a screen problem, couldn’t see anything displayed with a flashlight.
I found this forum post (I need help getting my DevTerm CM4 to boot - #13 by nathanbibb) which had reported similar issues but none of my attempts at anything on there have resulted in getting anything to show up on the screen. Anyone dealt with this kind of issue recently and has some solutions to try?
