This xenon I have has always did this. Tube shot works perfectly until you capture a ball in there and then sometimes it sticks in the saucer and never serves up the next ball for multiball. Only way to get it out is tilt it or release the ball manually. Is there a fix for this?
Yes cheddar works everytime. Never a problem until it's capture time. It just sits in there. Funny reach inside the machine and hit the tilt pendulum and it kicks it out no problem. Just played the game 5 times worked fine. I wonder if it flys in there too fast some time and it makes the 2 switch closures too fast? I've tried adjusting both switches. Cleaning them etc. nothing worked. I even swapped in my spare Alltek. Still does it. Ive researched a bit and seems others have reported this happening.
I had one that did this. on mine it was absolutely the saucer switch, it took me forever to figure it out... I believe the way it works is the first time it goes through, it uses the switch above the saucer to know the ball went through, then just automatically kicks it out. On mine, the saucer switch itself didn't work. The first ball would go through and kick out, but when one was sitting in there, it would just sit and wouldn't kick out...
once I checked the switch, I noticed someone had tried to replace the diode on it... but had put it on in such a way that basically the switch was shorted... so I'm not sure if the software disables the switch or what, but check that diode (the reason mine was shorted was because they had rebuilt the switch stack with something in the wrong place, shorting both sides of the diode together)...
If you set 16 through end on #3 (coin door test switch--backbox adjusts)....that will usually fix this.
You also need to pull both balls out...turn the game off/on...let it boot up...then let the balls drain slowly.
One goes into the front right...one stays in the normal trough....then you should be good.

Yep, that is the fix that worked for me. Any time you prop open the playfield, you need to do this.
I played probably 50 games on it. NOT ONE SINGLE time did it mess up. So I took glass off - got world record tube shots . At least 50 million points. NOT ONE TIME did it mess up. Hell if I know. It did it before this post 2 out of 3 games... Might change trough switches. The switches are the same as used in video games. Just have to pop the leaf off the old and snap into the new one.
By 16 you mean self test setting 16? set to 3? All mine 16-21? are set to 3

Yes...
And..watch for the after tube shot lane zipping by too fast.
If that rollover misses the scoring/trigger just once, sometimes it screws up a whole game.
Xenon is one picky beatchhhh!
Check the pins on the mpu. I had this problem when I first got my Xenon and a couple other weird things happening and I reheated all of the J connector pins on the mpu after cleaning acid damage and I haven't seen this problem since. Obviously that was a shotgun approach so check your schematic to find the proper connections
