Perhaps you have overloaded the pin by exceeding it's current capability, and the driver has burned out. Does that pin work at all now?
That's what I was thinking but I'm not sure how that would happen, its just the signal wire. What is an easy way to test that pin? Can I wire that pin as an output and wire it to pin 12 to test it?
Also do you think its the circuitry that's shot or just the chip. I should be able to just replace the chip for cheap.
