Hello,

we have this Pinball since a long time, it worked fine for quite a while, but we already bought it used and restored from some shop or similar (I was too young back then)

Well now though, after a long time of this Error ruining it, I want to go and fix it..
It seems to be harder than thought tho.

What I heard is, go to the switch test and check.
I did, it seems all the switches recognize when a ball is in the low area (I don't know the right words for it).

So if the switches (seem) to be alright, what else can it be?
We have 3 balls so it should be fine.

Checking wires and solders didn't help too much, I saw a wire pretty flattened from pressure probably, but with the Voltmeter it showed to have a connection.

I am obviously new to it, so any help would be really appreciated, such a shame if this "little" problem will prevent the pinball to work forever..

Greetings from Germany

But wouldn't it show false in the switch test if the switch had a problem?
Doesn't seem exactly logical to me :/
Thanks for the quick response tho.

I will check again, maybe more ideas what it can be?

Alright, I went through it really precisely again and I am certain that it's not the problem..

There must be other things that cause it?

The manual itself also only says it could be because of ball through switches or the ball shooter switch..
I am certain that they show contact when a ball is over them..

Any other ideas?

Are you sure? I wondered the same when I looked into settings and the standard setting is 4 ball multiball.
My dad said he was sure it has only 3 balls though..

Also, wouldn't the problem be gone if I switch the multiball setting to 3 then? cause I did and it didn't help :S
The manual also says the pinball can be operated with 1 or 2 balls as well..

Thank you for your answer

Well like I said, the switches all seem to work properly in the switch test (also if balls are used).
There must be some other things that can make this problem occur?

Sorry for the doublepost..
but this gets probably worse now?

It tells me about a problem with the Shifter High, which is Coloumn 4 I think.
Sometimes it also tells me about an entire Mass Short in Column (or Row? 4)
So could this be a loose connection?
When it doesn't say Row 4 short, I can use the Shifter High in the Test Menu, otherwise not...

How do people proceed with stuff like this? It tells me which colour the wire has, White Yellow.. but I can't really make a lot with that..

Would pictures help something? Getting really frustrated now :S
With all the Switch Matrix stuff and ugh :S

EDIT: It also seems to have memory problems?
When I change and save settings, turn off and on, everything is reset..

This probably was before too, I just didn't realize

Alright, I have about one year electrician apprentice experience (not much I know) but as far as I can tell, everything in the backbox looks quite decent, if anything a bit dusty. Fuses don't seem blown and batterys also look good (still give me 1.31V when 1.5V is wanted.)

If anybody has a better eye, also, the connector on the left is for the Knocker, which was just disconnected cause it was too loud for our taste^^

Down here I haven't found any disconnected wires, it looks more dusty or with oil or some other black stuff which gets on my fingers..but a relatively detailed look from me didn't help.
Except for these:

Would you guys think to use new wires here? They look quite done..but a connectivity test showed it should work (tested while they were still connected, not sure if it would also beep cause it can around a different way? Didn't think so though).

This is what the Switch Edge test shows, the closed ones on the right are all Opto Switches which afaik have to be closed, the one in the middle even says "always closed" so I guess that is alright.

One switch seems to be for the ramps (also one on the right) not sure if that is also a Opto, or if it's really a false switch?

This is how it looked when I had the Row Short.
But this time I got it through pressing a "switch" on the playfield, just to show, meaning, the row Short issue didn't appear this time.

Also, it seems the memory issue has been resolved?! Switched some stuff around again, turned off and on, several times. And it seems to have saved it.
Not sure how long, or why..but well?

The only Error it gives me on the start now is, "Shifter Error", which is still quite interesting, since the Shifter is also in the Row that was said shorted, otherwise, in the Switch test, the Shifter works perfectly fine?

So I'm back at the start I guess, the Ball Missing Error is still the main problem.

Maybe somebody got some ideas from the picutres or anything :S

Thank you!
