I have a WOZ Standard, which is connected with VGA to the monitor. There is some interference in the picture, so I would like to try it with DVI. But how do I access the monitor connectors? Is there an easy way to open the monitor from the backbox - what should one do in order to access them?

Thanks for any tips!

I tried bending down the backbox for the connectors and noticed that my monitor apparently only has a VGA-input, so no use to mess with DVI. Apparently I need to get some better VGA-cable due to interference though. I tried some other shorther VGA-lead that I could find in my storage, but it was not any better. Any suggestions on good VGA-cables are appreciated.

Thanks for the tips, I was so ready to blame the cable that those matters did not come to my mind.

It the monitor looks to be ok, maybe I should try this, since the computer has a DVI-output:

I have usually put my pinball machines into three parts when carrying them downstairs - backbox, playfield and cabinet. However, when trying to disconnect the WOZ's playfield, I noticed that the violet wires have been screwed into the power in the back.

What would be the best way to remove them in order to be able to be able to detach the playfield from the cabinet? It seems that there are no big connectors that one could separate.

Please share your best practices, if you have had to separate the playfield from the cabinet. Thank you!

If someone is doing same kind of carrying job - the simplest way was to remove the power as well and stick it into same plastic bag with the wires from the playfield.

I have some problem with the castle right door. It gave in a bit in such manner that the ball got into the castle, but however not into the hole. There was a ball search and the ball dropped into the hole and machine started ejecting the ball. However now only the left castle door was open, so the eject hole was banging the ball from the hole each time to the shut right door.

I am sure this is some common problem for which a solution has been detailed in this thread. However, any pointers to the solution or information in a reply would be most appreciated. If the fix will require the removal of the mini-playfield, I would be grateful from any instructions relating to that as well.

Thanks!

I will check. If there are instructions for removing the castle playfield, it would be good to have - or maybe they are in the manual?

Looks like it is a loose set-screw regarding my right door. How have you managed to get the set-screw to stick? I remember the earlier owner telling me that he had to fix the set-screw and I noticed the castle playfield flipper was set to be very weak. I put more power to it and in no time the door broke then.
Is there something specific about the orientation of the set-screw - how to ensure that its in correct place once tightened?

Thanks! I have removed the playfield, so now its time to put Loctite on the screws then!

Need to ask further guidance. It seems that loctite had been placed into the set-screw hole, so I will have to familiarize myself with how to clean the old loctite.

However, now when I have put the doors in their place, it seems that the latch does not open sufficently anymore. How can I adjust it to open a bit more? I think 1 mm should do it nicely.

Thank you for any help!

Thanks for the tip.

I noticed that someone had installed the left door a bit higher than the right door. This maybe was done to ensure the clearance with the latch. I pressed both doors down and now there is the tiny clearance issue with the left door and the latch. There must be some way to adjust the latch...

Thanks - I noticed that there was a small gap between the motor and the pole for the left door and I put it tightly together, but I will now adjust it so that the gap is there again. Then it will clear the latch.

I had my first try to put the castle mini playfield back. Something went wrong with the wiring I think even though the previous owner had numbered the connectors. I have to remove the mini playfield and try this again. I got some error messages, also the castle doors where banging open and shut and the wizard was rising and going down and also turning in its slot...

Thank you pinballinreno and LTG for excellent tips! I noticed when putting the miniplayfield back together that I had accidentally knocked J9 off from the left-side opto i/o board. I checked it now again and reinstalled - I think it was one pin off - my eyesight is not what it used to be! Anyway, after reinstalling, no more errors.

My castle and munchkinland flippers stopped working all of a sudden. Is this a known phenomena and what should one check? Thank you for any tips!

Any info, which fuse is it?

Thanks for the tips, I will look for loose connectors - hopefully it is not just a leaf switch, that would be too embarrassing

And LTG, yes, I do hate when it happens

Some testing done:
- flippers were ok according to the test, both switches on both flippers registered.
- I noticed that the slingshots were dead as well
- I tested magnets as well (coils-test --> put on repeat), it seems they are dead as well
- I checked fuses F702 and F708, but both gave the peep and I also tried to bend the fuse holders a bit to a more closed position to tighten their grip, but it was no help. F702 seems like the likely culprit, but did not help to tighted the holder and the fuse gave the beep.

It may then be some connector, I visually checked and did not notice any loose connectors. This might be a more difficult fault to hunt down.

Sorry all - I double-checked F702 fuse and its blown. I removed it the first time from its holder, but I think I may have misread the diagram and removed the fuse from the other end of the line or something like that...

I noticed today that in my WOZ there is some wear on the PF before the target that leads to the hole that launches the ball to the castle. Have you had similar problems and did you manage to find good ways to cover the wear? I guess otherwise I just put some mylar there. Thanks for any tips!

IMG_4140 (resized).JPG

I do not see it in their shop? Is it through support services? A decal would definetely be better than just regular mylar.

Submitted a question to JJP support about the decal. I see however that even that decal would not completely cover the damaged area in my pin.

Anyone with a hires picture of that area, please let me know? I am thinking about creating a sticker myself and covering it with mylar then. I guess I would need to cut out the insert area from the sticker, so that the insert could shine through.

I guess changing the playfield would be nearly an impossible task for one that has never done such work and that WOZ playfield exchange would be one of the most difficult ones?

I had this problem when I had removed the castle mini playfield and installed the wires to go from wrong holes... If you have done this, it might be worth checking out.

Anyone with a good picture regarding the area in front of the winkie drop down target, please send me a PM. I am trying to make some poor man's decal to cover the wear on my pin.

How difficult it would be to change the playfield in comparison to e.g. WMS tables? I have some wear in front of the winkie target, so I am thinking about doing this. The playfield parts are in good shape, so I am thinking just porting the parts to the new playfield to make the exchange easier for myself (i.e. without cleaning the parts). I have procured a rotisserie and this would be my first playfield swap. Anyone done this and have a website full of teardown pics?

Bump. Anyone with an extra playfield that could take the photo for me? Thanks!

I am thinking about making a sticker out of the picture and putting it there and then cover it with mylar.

Exactly - you can see the wear here: https://images.pinside.com/1/d0/1d081356711d85ecae910546edcc813deb4cf017/resized/large/1d081356711d85ecae910546edcc813deb4cf017.jpg

It would be great if you could take another pic, but not at an angle. Many thanks!

Thank you very much JIM_Z, brilliant!

This is so true. I had a part chipped in front of the Winkie target recently and I am in the process of repairing it and covering it with mylar.

I was changing the rubbers for my WOZ and noticed that there are some very difficult ones. Anyone know of any shortcuts on how to exchange them (= especially without removing the ramp or the castle miniplayfield)? It looks like removing the ramp is a difficult task. Have a look at the pic, thanks!

I am a fairly new owner for of WOZ, so my questions probably are such that have been already been asked and answered. In any case, if you can give a few pointers, it would be great.

These are the problems that I have noticed:

1) sometimes I notice that the monkey goes down its rail and tries to catch the ball at the magnet, but the ball has not been captured to the magnet. So then the monkey just goes up again without the ball.

2) the hounted forest -sign on the left. There is a tiny red light, but its not working.

Also, are there supposed to be some leds in the hands of the haunted forest trees (on the pop bumbers)?

Thank you for any tips on how to rectify the above!

Thanks for the info. I am equally frustrated for the lack of support and no conclusion on replacing my lockdown bar for my DI, as mine looks like it has been poorly handpainted rather than powdercoated.

Thank you! Its a great community!

Bump! Anybody here who has made a playfield swap - and better yet if that would have been your first swap. It would be nice to hear how difficult it was. I am planning on making the swap, but this would be my first swap and WOZ is full of stuff, so I am gathering courage. I have installed several playfield protectors and detached the playfield from cabinet many times when carrying the pins to downstairs, so I have some experience atleast in regard of those activities.

Hi! Sending a PM to you.

Hi!

I have a lightning problem with WOZ. I booted the game up today and suddenly I am missing half of the led-lightning on the playfield. More precisely it seems that leds #1-65, 67, 121, 126 and 140 (B) are out.

If I look at the chart for led boards on the manual, it seems that possible culprits are the small boards 15-17. For some reason board 16 seems to work however. Am I right to assume this?

Funny thing is that when I was testing the led-boards, for some reason the non-working leds started quite a lightshow with strange flickering. Have a look at the video:

What do you think - how should I proceed? When thinking about replacing the boards - are the small boards 15-17 similar to each other?

Thank you for any info!

I think my message might have got lost in the other light-related topic, any ideas on this one?

I detached the wires from led-boards 15, 16 and 17 and then reattached them. It seems that the boards get light now, but there is some strange flicker going on. What might be a proper next step? Have a look at the video:

EDIT: seems like led-board 17 was broken. Had one little board in the goodie-bag and replaced it. Seems to work again.

I lost yesterday half of my playfield's leds and GI.

Its a bit strange though:
- led 66 works (board 16)
- led 67 does not work (board 15)
- led 68 and onwards works (board W2 and onwards)
- led 65 and leds with a smaller number do not work (from board 17 backwards)

What do you think, which board should be replaced? Its strange, cause working board 16 is in the middle and on both sides of it is a non-working board.

Last time this happened, I think I replaced board 16, but it might have been the wrong board?

Thank you, I will have to investigate. I thought that I had found the culprit in board #17, but after I exchanged it, it worked ok only for a while and then the problems reappeared. It might be that there is a bad connection somewhere between the led-boards...

I have to check from you guys that am I having a led-board problem, or is this something else?

Now all the lights lit and in the start everything is fine, have a look here:

But a bit later in the game, the problems emerge like this:

And how to start figuring out, where the problem is?

Thanks for any info!

Thanks DCFAN for the suggestion - here is #15 bypassed.

The first video is taken after it was bypassed. Some strange flickering:

The second video is taken after I also remembered to turn the led off in the WOZ menu. Its better here:

For some reason the tail of the "yellow brick road" seems to sometimes be of different color than the rest of the yellow brick road.

What do you guys think - its better than before, but not fixed totally?

Can you tell by the pics - my boards are 5V unbuffered ones?

IMG_5513 (resized).JPGIMG_5514 (resized).JPG

Ah, ok, thanks, that explains it!

Was it so that the errors in my first video in the post #6827 were probably due to me not disabling board 15 in the menu?

Thanks everybody for the tips, board 15 it was then!

Anyone with some extra 5 VDC LED boards for sale, please send me a private message, I would need atleast a few tiny boards.
