Got Service Bulletin #133 done from the Stern website. Replaced R110 & R106 to replacement resistors and the sound is now lower. Looks like that friggin' annoying buzz and beeping won't be coming through the speaker anymore.

edit* Well, I was ahead of myself a bit. Most of the humm from the speaker is gone, BUT the beeping induction from the lights flashing is not gone. Annoying.

That humm and beeping is totally annoying as hell. Cannot believe someone hasnt figured out a way to eliminate it completely. Surely a resitor somewhere else would elininate it completely. Someone smarter than me needs to take that project on and rid us of the dreaded hum and beeping.

I am looking for a new plastic because mine is cracked. Anyone have a Free Parking plastic in good shape they want to sell? PM me details. Also need a new sticker on the bank door.

I wish stern made extra decals like the bank sticker to purchase individual as mine is a beat up too. Think you have to get the whole decal set.

Seems like someone would have a sticker made up on here to replace it.. Anyone make a mod sticker for the bank door?

I scanned in the Bank decal and posted it on my site. You can print the bank door picture onto a piece of adhesive.

In case anyone needs used plastics...

ebay.com link: itm

I've got a mostly complete set of NOS plastics, and a few used. If someone needs a specific piece, just ask.

awesome. Any idea the dimensions? I wonder how a regular adhesive print from like Staples will hold up?

I believe the bank door's measurements are :

2 1/4 wide x 2 height

Does anyone know what you have to do to get the community chest light to come on. I have checked the rule cards and theres not a word about it. Anyone know the trick?

Community Chest was added in version 2.33.

Software Release 2.33 Date October 11, 2001

* Added community chest rule

It should light when you land on the community chest space. It also has a part to play after Land Grab is completed.

Ok cool. Wasn't sure what the magical trick was to get it but now know what to shoot for. Thank You!

Hi, I was wondering if someone could set me straight on coils an diodes..

The Dice Eject appears to be wired backwards on my machine, but it is working. My understanding is that the Power goes to the Cathode (Banded) side and the trigger/drive goes to the Anode side.

I've attached a picture of how it is wired and I super-imposed a diode on the image to see it's orientation (it's hidden in the picture). Still learning, so any help is appreciated.

If nobody responds I can check when i get home but gonna be 2 or 3 hrs.

Hopefully this is what your looking for.

Awesome! Thank you very much.

So, mine is wired the opposite of yours. I'm perplexed as to why mine still works without frying transistors on the power board....

Sometimes it will just cause strange things to happen and not do damage.

I'm in the club!
My daughters and I have played a Monopoly pin every fall when we stop at Pizza King in central Indiana for the last 3 years. So when the time came to finally pick up our first one, as much as I tried to steer them towards something new, they shouted out "We want a Monopoly". I figured I could change their minds when we headed to a local dealer and they played a few others. To my disappointment, but their delightment, there sat a beautiful HUO Monopoly. It really is a fun game and perfect for them.
I'm completely new to working on stuff like this but I'm very ambitious.
There's some quirky "things" going on with it though - like the ball periodically auto launching.
I notice I don't have the latest version CPU - 2.51. The dealer is very cool and willing to burn and replace mine with the latest versions but I need to tell him what I want. I see the latest are 3.03 CPU and 3.01 display. My question is, are these the versions I want? And if not, what should I be upgrading to? Are the latest versions always the best?
Thanks.

The bad thing about 3.03 is for some reason they took out the code that lets go of a pinned ball with the mini-flipper. My machine had 3.03 and I had to get the previous version so I could get this feature. Otherwise you have to open uo the machine in mid game to free the ball which totally sucks.

So is the 3.01 rom the one that still has code to let go of the pinball with the mini-flipper?

I need to upgrade as the machine I bought has a much older version: 2.51 if I'm reading the display right. And I want to get roms that will let go of the pinball.

Yep you have to go with 3.01. It still takes it a bit to free up tne ball it doesn't pin it and just let go of it. Will go through a ball search sequence and then it will let go of the ball. Its not ideal but at least you dont have to take the glass off to free it.

I ordered from here and just requested the older rom version and seller said no problem. ebay.com link: Monopoly Pinball STERN Upgrade EPROM chips

Perfect. Order placed!

The one bad thing is that you will lose your high scores and your settings like free play so you have to go back in and make those chsnges which is no biggie.

I use 3.03 and haven't had any stuck water works issues. There aren't many major gameplay changes from 3.01 tho so do what makes you feel best.

I'm curious about the 3.2 ROM tho. It has alot of improvements but apparently crashes? Does anyone run it?

Last couple games i've played I have noticed some of my bank door hits aren't registering. Has anyone experienced this and if so what was the remedy? Is it just a dirty opto sensor problem?

I would start with cleaning the optos and the opto window for sure.

Hey does anyone still make a ramp fix kit like in SB 135 (pictured)? I heard someone was making one you didn't have to drill holes in your ramps to install?

I just made one a couple months ago. No need for holes drillled.
Have to look back in thread for full diagram and info to trace your lexan from a paper. I might have bookmarked it. I’ll look.
It’s VERY easy to perform. And fixed my airball problem 100%

It’s right around Post #410

This site has the diagrams you can use to cut yourself or send to a cutting place (like Ponoko):
http://www.pinballzone.com/tech/monopolyflap.php

I did it easily with a decent pair of scissors.

I bought this lexan pack.

Now I have a pack of spares to mess with if I ever need it

Perfect. Thanks!

The diode on my Bi-Direction Relay board seems to be bad (part 520-5066-00). Does anyone know what the specs are for that diode? I can't seem to find it in the manual.

Is the diode labelled?

It is. I need to remove it to see the entire number but it starts with i100 or i700. There might be more zeros under the diode.

D1 is a 1N4004. Any 1N400X diode will be fine.

The other diode (and filter cap) aren't stuffed on a 520-5066-00 on Sega/Stern games. They aren't needed.

Another tip: if your mini flipper doesn't go both directions in the DIAG->MONOPOLY->WATER WORKS test menu, often the issue is cold solder joints on the bi-directional relay board. All sorts of DE/Sega/Stern games used them as well and suffered the same issue.

Appreciate the info. Yeah, the issue is that the mini flipper is only going in one direction. I was going to try reflowing the solder when I get off work. It would be nice if that's all it is.

Thanks again!

The issue I had with it is the dice always roll the same number. If you land on a spot that hasn't been programmed (like just visiting jail), it will crash. I don't know of a work around for this.

Which version are you using?

3.20 is broken, which is why Stern pulled it from the website and rolled back (no pun intended) back to 3.03.

Run 3.03 and you'll be happy. Works great.

This is a bug is the 3.20 version of the ROM. It WILL crash, because it always rolls the SAME "random" number, thus it will eventually land on a non-programmed space, and the machine does that bright light flashing crash.

It would be nice if the issue in 3.2 with the dice roll not being random was fixed, so that the other fixes could be used on the machine. (the dice kickout bug being the biggest).

The version 3.02 (NOT 3.20) was never released. So 3.03 is the latest working firmware for Monopoly. If you upgrade from anything 2.xx or below, you must change ALL 5 display roms as well as the firmware rom.

I am in need of 2 plastics if anyone has them? The blue plastic by the upper right flipper is totally cracked in two. The other is the green/blue plastic on lower right playfield by Go to Jail. Please PM me if you have any one of these plastics?

Anyone have an extra door sticker they can send my way? I bought a decal set and either I didn't notice it didn't have the door sticker or I somehow misplaced it.

If you have a spare, let me know and we can work something out!

Having an issue with the MONOPOLY (STERN) DRIVEN WHEEL. The hole meant for a screw to tighten on the flipper shaft will not loosen teh small metal piece that was pushed onto the flipper. I was able to get the bolt out, and teh flipper shaft, but i cant reinstall the shaft. Any tricks to getting that metal out of there?

I might be misunderstanding, but the wheel should have a set screw. Are you saying there is another metal piece besides the set screw? If so, do you have a picture?

Well that explains part of it. There is no set screw, but there is a piece of metal in there that seems to push in if I try to fit a screw in there, but I can't loosen.
