Ok bad news and good news:
The Good. I changed connector CN2 on the power board and two capacitors 100 uf 200v. The caps looked like they needed to be replaced as the paper was rolling back. The connector was all chard on one of the pins. So I can play the game no issues.
The bad. Now the Dot matrix display does not work. At first I thought it did not display anything, but then at some points in the game it appears to show a faint sel of lights on the botom left had side. it looks like the display on an mp3 player when playing music. I can see there are two connectors from the digital display, one goes to the power ( I tested the conninuity of heach wire and looked good), the other goes to a solid black hard ribon cable that goes to the CPU. The cable to the power board goes to CN5 and CN10. I reseated the two cabels on both end and no change. Before the changes, the dot matrix display would work fine, but don't beleive the two changes I made would have this effect, could be wrong.
As I said in a past I have never worked on pinballs before but plent of arcades. Just need a push in the right direction, Anyone have any ideas as to what to test and what the results should be so that I can fix this dot matrix display?
