OSP-5000L-G white background on display

Hey guys, I have an LC40 that works great except my colour display has a white background instead of black. It makes the white text items invisible which makes changes to offsets something of an adventure. Anyone have ideas where to start on fixing this?

Probably contrast or brightness pot on the back of the CRT.

I should add that it has the okuma replacement lcd monitor, not the original crt
