Quoted from jdemarti:the ship pin extends, holding the ball in place. I have to hit a flipper in order for the pin to recess back into the playfield.
Investigate it. Is the pin not centered in the hole and sticking on the sides of the hole it goes up and down in ? Coil sleeve cracked, dirty, or broken. Spring not doing it's job.
If vibration from a flipper flip drops it, you have a mechanical issue going on.
