My guess would be the red wires are for the filament voltage...Black? umm dunno..could be a ground wire...The ribbon cable will connect to some form of microcontroller..

Try Googling VFD display...you may get some hits on what voltage is need for the filament voltage...

VFD's were common in VCRs...as well as other domestic apliances..Dunno what this could have come from..

Some info here worth a look..........

Well if you guys had this part and wanted to run some tests on it see if you can get it to work. What would you do. I was thinking putting maybe 5 volts dc to the red and black wire to se what that does.....and thats about all I got for now.

Have you told the local electrical supply authority? ( I can just see all the lights going out....:) )

Good luck..hope you're well insured :D
