You got the LCD from NCK, correct? I don't know if any others would be significantly different or not, and don't want to know just yet.

Yes, its the NCK LCD

Yes I've tried powering it up with a plug in power supply. It did the exact same thing.

What if you disconnect pins 2,3,14,17,18,19? if disconnecting them all helps, is there a combination of pins or a single pin that the problem can be isolated to? Hit reset bewteen pin connection tests so the LCD will reinitialize.

I'll give that a try. I have been double checking the wiring but there is a lot of wires. I'll try to see if I can isolate it.
