Hi, I’m working on a build with my son, we managed to get the backlight on after step 12 (and some solder re-work) but nothing else: no text displayed, and no sound from speaker either. Potentiometer for the backlight works fine, for what it’s worth.
We went ahead and did additional steps to try the reset with button C, but that didn’t help either.
Images included for our soldering; I also checked the CPU and it seems to be seated pretty well.
Any tips appreciated!
