I have a problem with a power supply/ solenoid driver board as-2518-22.
When I got this game I noticed that the flippers was active when the game was just power on and no game was activated.
The knocker coil was also cut. I reinstalled the knocker coil and took the board out of the game.
I tested the game with a board from my Viking game to isolate the problem. And with the Viking board everything works as it should.
Now back to the broken board. I tested al transistors. Q5 hade not the correct measurements. I changed Q5. I also changed Q3 and Q15 because they are related too knocker and flipperbats. I also changed the diods related to those transistors. Then a mounted the board. The problem still exists. The knocker coil energy’s and bats are on. Turned game off and pulled out the board again. I now put in a new flipper relay, but the problem is still the same.
Are there anyone how have hade this type of issue? Or have any solution for this?
And sorry if my english is a bit messed up, I’m from Sweden
