I'm trying to get a 2x20 LCD screen working on my computer and I followed the circuit instructions here for connecting it to a parallel cable: http://lcdsmartie.sourceforge.net/circuits.htm
Anyway I plug the power into the 5v on the molex and the black squares come up, good it's working... not quite. When I plug in the paralled cable the LCD goes blank. I've checked the connection many times and as far as I can tell I've soldered everything correct. Any ideas on why this is happening?
