Hey there Pinside!
I've recently cleaned up my Black Rose, stuck a couple LEDs in to test them out and replaced a broken switch to name a few fixes, but one problem I have yet to fix.
The cannon in the middle of the playfield will only fire on certain angles. It can make the center shot, the ramps and both loops, but shooting at any of the standup targets usually results in the ball not being released. The sound effect plays and the DMD displays "Shot Missed" but the ball remains in the cannon. It is released once the machine does it's ball check, allowing the game to still be playable, yet annoying if a shot to the targets is made.
I'm wondering what causes this and what a possible fix would be? It's probably to do with the solenoid down there, but the fact that it only fires on that angle during the ball check is fairly odd. I don't know much about the cannon setup or solenoids in general, so I thought I'd ask here.
Thoughts and opinions?
