Hello everyone. Suddenly as I was playing my Bally Strikes and Spares, I realize that I had a mess with some switches. I hit one and fires another! I looked in the switch matrix but I don’t know very well to read it…. My first thought as I saw that the problematic switches where in the same row, was that a diode has to do with that. So, I replaced all diodes from all these switches, I desoldered the small caps and I looked for something obviously like sorts etc. nothing found. After that I had the same problem. I friend of mine told me that maybe the u10, u11 chips where bad so I replaced them both. Nothing again. Same problem. The problematic switches are the 4 that I marked in the diagram, but in switch test it involves and the credit switch. I mean I push the target and the number of credit switch appears. So, I disconnected the front door to see if the problem was that. Nothing again. Same problem. Any ideas guys? What should I do next?
