hi.

i have a CFAH1602A-YYB-JP display module, and have wired it to my pc's parallel port. the lcd powers on fine, and it shows one line of black blocks when i turn on my pc, but then when i try to use the Crystal Control software so that it displays something, it just shows those black blocks, no change... i have checked and rechecked my wires, and i even plugged in a different lcd module to be sure it was not my pc's parallel port that was malfunctioning, the other display works fine. im not sure what i may be doing wrong....
thanks in advance for anyone's help!!!

thanks for your reply. well, i used the cables for the one that won't work on one that i know does work, and it does tha same thing. so i guess the problem lies in the cable....
i am using a ribbon cable, maybe that is the problem? its less than 2 feet in length. hmmm....
