Title: Monopoly Pin--Lot's of noise through Speakers
Post by: hamltnh on November 27, 2010, 11:21:20 pm
I just bought a Monopoly (2001) machine--there's lot's of noise coming through the speakers when not playing a game.  The noise sounds like 60 cycle hum amped up, but the noise does change pitch/volume slightly as the general illumination goes through its cycle when the machine is in attract mode.  My question is whether this is normal for a Stern machine (the person I bought it from says it is...)?  This is my 1st experience with a Stern machine.  My other machine is an Indiana Jones (Williams) and that has very little if any hum/white noise coming through the speakers when not in a game (at least that I can hear....).

I believe I have heard that coming from a Stern pin before but I'm not 100% sure. I do know that my High Speed will do that a lot but I kind of think of it as a mark of the era.

All Data East and Sega pins have a hum when in attract mode. This is believed to be caused by a grounding issue with the game's electronic system. All modern Sterns will have this up until World Poker Tour which is the first SAM board system game. Monopoly uses a Sega Whitestar board system. My home used only Terminator 3 has the hum as well.  :dunno

Newer Stern games WPT and after do not have the speaker hum.

Drove me crazy on Jurassic Park.  Only solution is to wire in relays that are toggled by the flipper enable and cut out the physical connection to the speakers.  Or just sell it.



I found this link:

Wondered whether anyone had tried this solution and whether it had worked for them--this guy sounded pretty definitive that he solved the problem....

There are two volumes, one is the dial type & the other is software/menu based

Turn down the physical dial & turn up the software volume...if that doesn't work adjust them in the opposite direction...if that doesnt work sell it to PBJ

Its a metal stick stick on a metal box near the coin door inside the cabinet on the right side (I think its flat on one side for a knob to slip on but it never happened).

This is the case on all 3 of my Data East machines, take a look inside yours & see if that attribute survived through Sega & Stern....might have one.

Whitestar games don't have a physical volume potentiometer.
