Hello all,

I have just picked up a Data East Star Wars pinball machine, I am new to pinball but have many EM games.

I have been able to get the machine back up and running but for some reason when I get the Death Star open for tri-ball it will not register when the ball is shot into the hole.

The same goes for the chute behind the Death Star and the pit just in front of R2D2.

After a few seconds the machine searches for the ball and will shoot it out the wire return ramp.

I have checked the switches in diagnostic mode and they all show up on the DMD when actuated.

Not sure what next steps to take… possibly the diodes on the switches?

I assume the wiring is ok since I see the switch actuate in diag mode.

Any help would be greatly appreciated, I have searched the forum and have not seen anything on this particular problem.

Thanks in advance!

When activating the switches, do other switches activate too?

How are you activating the switches - using a ball or something else?

Posting your question in the thread "Data East Star Wars Club...Members and fans welcome" will draw more responses. There's lot of help there to get this figured out.

I would not be the least surprised if a bad diode somewhere, on my DESW there was four of them for some reason.

Thanks for the response!

I tested the switches by manually triggering them and with the ball.

Both ways displayed the switches on the DMD in diag mode.

Only one switch actuated at a time.

I have found a few bad diodes so far but only on lamp sockets.

Did you check the one on the bottom of the subway from the deathstar to the VUK?

Yes, both switches were displayed on the DMD when separately actuated.

Anytime the ball is in the subway the machine has to search for the ball as if the CPU didn’t get the signal even though the switches tested fine.

It doesn’t matter if it goes in the pit hole of the return or the Death Star or the drop behind the Death Star.

Totally weird to me.

Are the switches standard leaf, micro, or opto?

Micro.

#10 6 months ago

You might just need to adjust the leaf on the mirco switches a little. I had to do the same on my Robocop.

They may trigger on a controlled switch test, but it may not be clicking when it's just regular momentum and gravity.

Micro with a diode.

I tried this already, tested it with a ball and everything looked good. But during game play it still doesn’t register.

Thanks for the support!

Here are the only two switches.

Update…

After testing the switches over and over during game play they will intermittently register. It seems to rely on sequencing of when the switches are hit.

It shows I am running cpu 1.03 on power up but I am questioning the CPU chip installed as all of the wiring looks good and the switches/diodes test fine.

Here is a pic of my CPU.

Possibly the programming is off/wong?

Thoughts?

Thanks everyone!

No, you would get a checksum error.

I suspect a diode or connection that is flaky during operation.

You never sent a picture of the V.U.K. assembly.
What does the V.U.K. assembly look like??

#17 6 months ago

Its directly below the habitrail opening on the left side, to the left of R2D2.

I wonder if the V.U.C. assembly is assembled wrong.

Easy enough to test switch and the ball does pop out on ball search.

True, But what about the ball rest cup?

#21 6 months ago
Quoted from vec-tor:

The cup is the trigger point for the switch.

In test mode, just take a stick and press the cup down.

I'm pretty sure either switch will trigger triball operation though with the VUK being the backup.

I will try this tonight, didn’t know there was a switch in the VUK.

Thanks!

So after reviewing everyone suggestions, I took a look at the VUK and the plunger tip that actuates the switch was gunked up and stuck down which caused the switch to be stuck on as well!

Why this didn’t show during switch diag is beyond me.

If it wasn’t for everyones help I wouldn’t have seen the switch there.

Hopefully its not weird but I love you all for your help and wisdom!

Really appreciate all the help, now my machine is up and running 100%!

Now time to add some led’s, PinStadium lights and a color DMD!!

Most likely it's a special switch. Special switches aren't part of the switch matrix.

Nope, Switch #36 left VUK is part of the switch matrix.

Glad you got it sorted out. Don’t forget the most important mod - Pinsound. It transforms the game.

That is awesome!

What sound file/patch are you running?

Neo or Plus Pinsound board? Shaker motor?

Thanks!

Order a new switch just to be safe and a kicker plunger rebuild kit.

Better safe than sorry... lol

Thanks!

#29 6 months ago

PinStadium Neo lighting added last night, they are seriously awesome and Scott at PinStadium is amazing!

Added some black Jedi pinballs as well!

Thanks!

The sound mix is the one I put together. It’s available in the community.

The board in that game is the original Pinsound one.

I don’t have a shaker in mine currently; but, it is compatible from what I recall.
