I can't begin to tell you how many articles,posts etc i have read in regards to the blanking signal on Williams pinball circuitry. #$#
I have basically replaced every IC,tranistor, the 555 timer and the 40 pin connector in the line of the blanking signal.
This is where i hit the brick wall !
The only advancement made after all the replaced components was upon power up i get random sounds. ( Original BK sounds )
Once powered up the only access i have to the entire game is the sound board test button... If i press that i get the sound test as it should be....Nothing else !
BTW thanks to everyone who has chimed in so far, i appreciate it.
