I tried powering the GEM up without SD card, to see if LCD backlight worked, nay. Tried with another LCD I have from a second GEM kit, not even backlight too.
It feels like a HW issue to me... I tried a couple of commands via SSH, but to be honest, I cannot tell if there is anything wrong or pointing to the issue in there. (see below)
May anyone be able to help, please?
