Hi, so, I finally got all my parts soldered together and in testing the various parts, the display board was glitchy. Per the instructions on the final assembly I tried pressing down on the pin headers, and that sorta helped a little bit, but the glitchiness came back. Removing it, then more pressing down, then reattaching it led to a display that just plain won't come up at all now. I'm afraid that maybe I damaged it. Is there anything else I can try to bring it back to life? And, if none of that works, what part is it so I can order a replacement?
Also in my troubleshooting I have come across an issue where there's constant noise coming from the oscillators and when the display WAS working it was showing activity as if input was being triggered. I assume that when no MIDI/etc are coming in, the thing shouldn't be producing any sound, so I probably have a short or a floating pin or something somewhere. Any idea where I should start looking?
(And, now I wish I'd just paid extra to have my kit preassembled. Holy moly has this been an arduous build...)
