So I have a Maiden Pro on route. While I was cleaning it I felt the newton ball for the Mummy shot seemed loose. I figured the nut under the playfield worked its way loose. Nope. It was on good and tight. When I lowered the playfield, I was able to just pull the ball right off the post. Isn't that thing pressed on the post? I can't imagine it just sits on there with the plastic above it to hold it down. Anyone know if this is supposed to be solidly attached or just sitting on the post loose enough to pull the ball off?

Oddly enough I changed my coil out and now I’m getting more misfires. Set strength to 235, and about once every 4 or 5 times the shot just bricks and misses the loop completely. Manual plunge is a crapshoot also-sometimes bricks, sometimes doesn’t have enough power to get around, and sometimes perfect. I need to check the alignment of the playfield to see if that’s the issue.

Definitely need to get the manual plunge working before auto-launch...

I'm curious...did you fiddle with the guide prior to installing the new coil?

I'm not so sure about that--my auto was 95% or better right out of the box and the manual was terrible. I got the manual to 100% by adjusting the mechanism placement and the auto plunge absolutely tanked. Took forever to get it almost back to where it was. How adjusting the manual mech screwed up the auto launcher is baffling, but that's how mine went.

Interesting. The shooter mech is voodoo Mine is working great lately, but it's given me PTSD...

This same thing happened on a brand new IM pro we were playing on location. All of a sudden the game started spitting out extra balls in the lane. We couldnt figure out what was up then we realized the mummy newton ball and captive ball were gone. The owners opened it up, we looked the pinballs over and yep, one had a hole in it. The ball had just come right off. Ended up hammering it back onto the post and its stayed in place far as I know. Seems like a drop of super glue or epoxy might be a good idea.

How are you guys correcting manual plunge ? It hits the rubber on top of skill shot pretty much all the time. I tried moving shooter assembly to line up ball with shooter. My auto plunge is about 95% and don’t want to make any moves that would effect the auto plunge. Any ideas?

Thanks. My slots look pretty even though.....

I didn't have either of those with me but I did have some locktite. I don't think that'll hold so probably just going to order a new newton ball. Hopefully it holds for a few weeks.

See post 1854. My advice, leave it alone.

Thanks for the advice. I don’t want to fight with auto.

Did you try turning it down lower? I think the one with the new coil here is like 225 and makes it 90% of the time.

There are plenty of soft plunge skill shots to aim for, which is what I usually do. If your auto goes wonky, then I'd (try to) fix them both--but if you are getting 90% or better auto launch I'd sit back and enjoy it.

One thing I noticed is that if I rotated the shooter the ball would not hit the post by skill shot. The rubber on end of shooter was fully seated but seemed to be bend in one direction. I tried cutting a small portion of the shootet rubber off for a snugger fit. That and not fully plunging the ball seems to have improved manual shooter. The full plunger extension seems to affect the trajectory. Manual plunger now working great if not attempting skill shit. Thanks for all who gave input.
Problem whole time may have just been fully extending the plunger.

I did not. Just tried to wiggle the playfield a bit.

I did-same result.
I think it has something to do with the way sits before it gets shot.
I’ll keep working on it. Like most here, I’m totally crazy about stuff working correctly, so I’ll get it.

Just changed out coil and auto working perfect. Not missing at all. Power at 255. I know recommendation is to reduce power but it’s working perfectly.

have you got trooper yet? If not get that and see how it works. The reduction in power is not for the initial ball launch but so that the balls don't overshoot trooper.

glad that you fixed it. but thought I'd comment on this. For a long time it will work and then as the balls, playfield etc get crap on them the ball starts to slow... so fitting the coil works well.

The balls hit the right post and then line up for the charge behind the left post. Isn’t that what it’s supposed to do?

Pulled the 22 year old Newton ball out of NGG to replace the 1 month old broken one in Maiden. Crazy.

This is the new normal at Stern. Seen quite a bit of it.

Common issue on the IMDN games but hasn't caused any issues that I've heard of.

From ghosting to planking to bulging... it's always something with their pf's. Brutal.

Well, I just spent an hour and thirty working on the bottom sarcophagus switch.... We'll see how long this fix works...

Nevermind--none of the adjustment worked as it all went wonky again today. I believe the switch is so stiff it isn't going to work no matter how I bend the arm. Next up, taking it all back apart and swapping in a roller switch...

Has anyone noticed having issues with the sound all of a sudden becoming much more clear and more bass? It's almost as if the sound changes similarly to when your ears pop. I've noticed it happen a few times on my premium and again tonight.

Yep it happens to my game and others that i know as well. It will probably return to normal soon. Either that or maybe i just get used to the change, not sure?

Was playing my game last night when I noticed that if I hit the flipper button while the ball was in the shooter lane it would score 1k points every time. I went into switch test to check it out and when I hit the flipper button in switch test mode "top ball sense" would come up on the display. Is this the sarcophagus lock problem, if not does anyone know what switch it is and what I need to do to fix?

I don't notice the change in sound clarity until it suddenly improves. I'm sure there are times I'm playing and the sound is subpar and not noticeable until it spontaneously improves on its own.

Its the utterly shite design of the captive ball. You need to adjust it until it works, read the rest of the thread.

n1teowl did this do the trick as my game has just started doing the exact same thing.

...and when Riffrider mentioned spring, presume it's that little spring that's part of the mech (the only spring I think).

I replaced the coil for the auto launcher with the one recommended by NeilMcRae and PinMonk , but am still having the ball brick into the post at the skillshot about half the time. I have the power set to 205, but also tried 225, with the same results.

Can someone that has their auto launch dialed in, post a top down pic of the launch kicker arm to see how the ends of it are resting against a ball in the shooter lane?

can you take a video please?

Here are two slomo videos.

Also noticed the end of the guide is a bit hammered and it might be throwing the ball trajectory off sometimes.

I'd loosen and adjust the top guide rail up just a tiny bit.

yeah the guide looks suspect on that, it needs directing more downards.

Neil.

Thank you guys. I will adjust and report back. For clarification, by downwards do you mean loosen the screw and push the guide in a bit and then re-tighten. Or bend in the the top of the guide a bit.

try first without bending it.

Neil.

Might want to get rid of that bump on the end of the lane guide first. Even something that small can redirect the ball.

OK, thanks again guys, I think I’m good to go. I polished the end of the ball guide on my grinder to get it smoother. I adjust the guide at the end as suggested, too. Now it makes it around the loop 9 out of 10 times.

Yeah, pretty sure that little nub at the end was most of your problem. Glad it's all good now.

Sorry to bump guys but I'm still getting this thud kinda sound? Any help at all? Did adjusting the spring help?

So, my newest problem is right when you start a game, instead of giving you a chance to pic whatever song you want, it makes you take 1 song, along with saying the sarcophagus lock is open. i made a video of the damn thing with my phone, but can't for the life figure out how to upload it here-says it doesn't accept .mov files.
Either way-anyone have this problem before? I'm assuming its something with a switch involving the sarcophagus.

Thanks

Yeah, would be a switch activating one of the balls. needs to open slightly I'd say.

is the an LE/Premium? if so likely captive balls. Put the game into switch test and you should be able to see what's causing it quickly.

I have something that I hope is more of a question than a problem. I have a Pro, and am wondering what is supposed to cause the right ramp flasher to activate? (This is the big yellow flasher at the top of the right ramp). I can test it in the diags and it works fine, but I don't think I've ever seen it come on during normal gameplay. I thought this was odd since this is the recommended flasher to control Pinstadium lights for this game (I used another flasher for mine, but was thinking that if I HAD used the recommended one I wouldn't have got much in the way of results!)
