LCD Troubleshooting

(1/1)

lugnuts:
After almost a year on the back burner, I have unit #857 powered up and alive on the test bench.

The LCD is not working, does anyone have a link to a similar experience or a troubleshooting/FAQ?

The brightness and contrast resistors are not installed, just the J1 to J16 wire, and of course the 9 main wires to the board. I am getting +5 volts across DB1 and DB5, and that is all I know to do at this point.

Any help would be appreciated.

excellent, It's always great when it is something easy.... kind of like soldering the MAP sensor in upside down :)
