This is my first post to the forum (been lurking for a while) so please excuse any newbie mistakes. I have a Black Rose that started having a problem every now and then with the ball eject from the Broadside hole. Every now and then the ball would not eject, the solenoid would not fire or the machine did not know to fire it. The machine would go into meltdown and would start ejecting everything (obviously looking for the "missing ball" that was stuck in the hole). It has finally failed completely and now it gets stuck every time. To complicate things the entrance to the Broadside hole has a little gate that hangs from the top and complicates even getting the ball out. I found a coathanger and a lot of patients gets the ball out but the game is unplayable.
Where do I start diagnosing the problem? I have a bit of technical know how as I use to be a computer technician in the old days of computers, Apple ]['s etc, but have never applied it to a pinball machine. I also have a Firepower which I get serviced professionally but want to have a go at this problem myself before calling in the cavalry.
Any tips would be appreciated.
