I am currently working on a flipper board for Rocky and Bullwinkle. First thing I did was check the tip 36 and tip32, because I has fusus blown on the board. Replaced them.
Power on the game and all is good till I press the flipper buttons, then high voltage fuse blows and shorts out both transistors.
So, figure it might be the two scr, replace them, then the two tip's again.
Same thing, blows fuses and shorts the tips out as soon as the buttons are pressed
All the smaller pre drivers seems to test good with meter and tried another board and flippers work. And it happens on both flippers
What else on that flipper board could I be missing?
Any help would be appreciated.

Also, I have never seen this board work, came to me in this state

Yes they do.
I did try a board from another game the flippers worked fine

Any more ideas?

On the flipper board it blows left and right with corresponding button
