I got a futaba 20x4 too. Mine has a black spot in the corner too, works just fine, it's not a problem.
Old Systems retired due to new car
New system at design/prototype stage on BeagleBoard.
I just picked up a Futaba 20x4 off of ebay, but I can't find the pin-outs for this sucker anywhere. It's a 2x8 pin interface, so I didn't want to guesstimate using the 2x7 format.
Can any of you guys help?
