It should be quite easy even without schematics. 

But after posting, I realized that a panel of this vintage probably has a
bias adjustment, labelled "contrast" or something similar. If this control
can change the display from "off" to "black", then that's all that bias can
do. If it is all the way at one end for best display, then changing the
bias range could make a real improvement. 

The next thing to try is more drive, but that's harder to do.
