The serial port working is promising.

All I can think of is do a comprehensive check. Like some arduino script that can use the serial port to turn the pins high and low (or read them) and tell you what lcd pin should be at what value, and the builder would follow along with their volt meter (or an LED + resistor), touching it to different LCD pins.
