…or you could try updating it. might fix the problem. i tried updating mine before (not that it was problematic in the first place) but the update didn't go well and left my ModFactor behaving a bit like what yours is doing. The switches' LEDs won't turn on and the display was stuck. I just tried updating it again and it finished updating and the pedal worked fine after that.
But it might be a good idea to just let Eventide know. At least you're using your warranty.
