Quoted from vireland:
Yeah, likely one of the 8b, 8c, etc boards. I don't think it's code (unless we're back to a bad SD) because it's not doing it on the TMNT Pro with current code here.
As far as the code angle goes, I’m wondering if there is some combination of things that I could’ve done, inputs in quick succession perhaps, to scramble something and assign some variable in the code somehow, otherwise agreed: If it were an inherent thing to this version, it would a) be more widespread, and b) likely have happened sooner.
But yeah, for now, seems somehow, for some reason, those circuits are remaining closed, somewhere in one of the downstream boards...hopefully Stern will get back to my email before too long (the KICKERS number isn’t operating right now), and even more hopefully, the likely necessary board replacement will be gratis!
