So I was recalibrating the dual extruder setup because it was a bit off on my last print, no idea what I did but the LCD wouldn't come on. Figured I might need a reflash because when I plugged it into the PC the board showed up. Arduino read it and the serial number but couldn't upload a sketch.

After tinkering around a bit I swapped the two micro fuses and low and behold, the LCD came back to life.

F3 - blown fuse - verified with the multi-meter.

Now I'm down until next week unless someone has a source for fuses in a brick and mortar store..
