Thanks, that helped.
now i know it isn't the wiring. It's the initialization, but how do i go about it? i have all the documents and i can send it to you if you need it.

The two black bars are the test signal - I take it this is a parallel display? If so install port95nt and lcd centre and try again, just might be problems with the lcd software you're using not being able to write to the parallel port.



p.s. if it's not software then it does sound like a wiring prob.
