Following the replacement of the entire flipper assembly, I made the mistake of adjusting the EOS stroke while the game was powered on, and inadvertently contacted the lane change switch and now column 5 switches don't work. All related coils work in coil test mode. Additionally, the A/C relay clicks on and off during the test, and all 'A' and all 'C' lamps/coils work in test mode.
So, I believe that i blew the transistor in position Q43. Thoughts?
If so, I've found conflicting info on what transistor should be used to replace the one at Q43.
2N3904 or 2N3906? Or something totally different? I can get these at RS so that would be nice if one of them was the right one...
Any advice is appreciated!
