I have a scorpion system 6. The displays work sometimes. Then all of a sudden they will all go blank. Like its looses power. I can look off the side and see the orange dot on all of the displays. So they are getting the high voltage. I can turn the game off for a day or two and they will start working again. I am running a rottendog mpu so the display signal is good. I think something is going on with the displays the self. Most likely the master. Just not sure what to do. I have looked on pinwiki and what not. But didnt see how to figure it out.
