It could be a bad solder joint. Because of the way the LCD is mounted, the display pins practically "float" a bit above the pads on the board and you have to kind of "bridge" them when soldering by building up a kind of blob of solder. If the pin(s) are too high or the little solder "ant hill" doesn't quite reach the pin, you could have an intermittent there..

I've built 2 K2's and on each one I've caught an insufficient solder joint on the LCD pins somewhere during inspection and had to reflow solder on it. So it's possible that could be what's going on.

So you might try removing the front panel (a pain but doable) and inspecting the solder joints?

This seems kind of silly perhaps, but the first segment - leftmost - in my LCD only seems to illuminate about 10% of the time. Is this just an issue of tightening something up or is that part of the display going bad? Not a huge issue, but it would be nice to fix it.

Thanks and 73
