Hi! So, i trying to find solution on forum but didnt find any topics which can helps me. I have Grand Prix/NASCAR pinball which have issue with coil Q5. Before this it have issue with coil Q1, but it was issue with U1 Chip, i changed U1 it and Q1 works fine. But, Coil Q5 still keep blowing fuse and burn transistor Q5. I change capacitor near transistor Q5 and put new transistor on Q5, it works fine few times. i turn on and turn off machine. It works fine few days, but when i come back next day, fuse blows again and transistor burn also. I think maybe issue was with coil. i swap the coil and it works little bit and again same result, fuse is blowing, transistor burning. Any advices what it can be?
