I am having two issues I hope someone can help me with. The machine is a Robocop by Data East.
1.) I installed a flipper rebuild kit last night and now the right flipper makes a buzzing, humming type noise when used. Didn't do this before I installed the rebuild kit.
2.) The left slingshot does not work. I have checked everything I really know how to check. There is continuity back to the board. The diodes are fine. New coil. There is a capacitor and resistor figured into the leaf switches...those are fine. I'm not too sure on how to test the transistors on the board. Can someone tell me how to do that? And what values I should get when I test? It definitely looks like some of the transistors for the solenoids have been replaced before. Oh, and I checked all fuses.
Any help would be appreciated.
