VFD won't display anything

[coorslight115]

The chip was in backwards but either the broken MPU protected it or I got real lucky.  Finally decided to take apart my perfect working DRWB machine and do some testing.  I took the daughter board w/chips off the broken 1270 board and put it on the good one out of my DRWB machine and it worked.  So I was able to isolate it down to the actual MPU board.  Ordered a new (used) one from Blue Ridge Slots, installed the daughter board and cleared a few errors and up she came.  I only have a 31 Key chip and was not able to figure out how to set the Accounting denomination so the machine thinks quarters in every way except for that poor counter on the side that has to do every credit X25 because the accounting denomination is set to .01.  But a least its up and running, back lite reals are working, sound is great, glass is good, after I cleaned off a few years of dirt and nicotine it looks and smells better so out of my purchase of three machines two are up and working.  The third one I'm afraid is gonna be the one that kills me, may just have to part it out and use it for a parts machine but we will see.

Thanks again for everyones help.

You need to clear the machine to set the base accounting. IVC0097 for standard boards or IVC224 for enhanced board. I have them if you need one.
