I need help guys. I just finished soldering switches in my ps2avrGB PCB. And while it was working properly, once I started hitting FN+any button (I tried shutting off the underglow using FN+another key) it started autopressing random/specific keys and now there is no way to revert it. While I am not really good at soldering, I think I did a decent job from it, and I did not touch any diodes or made the soldering iron stay on the pcb for too long.
Here are some pics:
And the random autopress from a key tester
Bad PCB? Any ideas or suggestions? I still have another PCB but I do not have any idea how to test FN+key becuase when I short the pcb with tweezer it always presses multiple keys.
