Replacing a VFD (vacuum fluorescent display) with an LCD Display
I saw 5 VFD-related signals from your list: VFD-GND VFD+32V VFD-CS VFD-CP VFD-DA.
GND and +32V are pretty self-explanatory. 

Googling for "CS CP DA vfd" gives  datasheet for ML3289 / ML3288:

Thus, the VFD controller has SPI interface (where SI is called "CP" for some reason) with a somewhat complex command protocol. Read datasheet for details on protocol. You will want to use "arduino SPI slave" library.
