I installed the Hyperpixel 4 on both units, reflashed using both raspbian full and raspbian lite. Followed the instructions here : https://learn.pimoroni.com/tutorial/sandyj/getting-started-with-hyperpixel-4
nothing on my hyperpixel when it reboots. not even a backlight. able to ssh into both units.
do i have a defective hyperpixel? spent almost 8 hours today following the basic instructions and it’s not working.
