If the layout label is still inside, get a bright flashlight and a magnifying glass (or take a pic of it and blow it up) and see if there's a contrast preset trimmer somewhere in the center of the board.

Haven't popped off the back cover yet, but I have visually confirmed the existence of this preset control (it is labeled "cont. preset" on the board). Good looking out!

Now that we know there's something that can be adjusted, how would you suggest I go about this? Better safe than sorry.
