The problem was a loose resistor connected from the power supply to the contrast control, someone had replaced it at one time and just cut off the old one and twisted it on to the old leads without even using any solder on one side and it came undone on that side, I soldered it directly to the board. It works now for the most part, except I can't get enough vertical height.
