Hello!
I have a 20x4 white on blue CF display.
i wanted to hook it up the parallel port of my computer.
i wired it according the 'standard' wireing-plan found on nearly every modding-page on the net.
but when powering the display nothing happens, no 2 solid lines and nothing when jalcds has begun running.
i checked the wireing about 12 times, used a multimeter to be a 99,99% sure and i can assure you: i did everything correct.
what do you think? may the controller unit or what ever it is may be damaged or something like that? the white backlight works perfectly.
i am really desperate as CF displays are not the cheapest![Frown :( :(](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
