Wizard of Oz
Jersey Jack, 2013I just recently replaced a GI light board and a couple of light cables in my WOZ, and am noticing while in attract mode a buzzing sound that gets louder the more playfield lights are lit. Pretty loud at that time. I don't recall hearing it before, is this normal? Replacement cables came from JJP. Thank you!
There was some fiddling I had to do with the mini jack on the pc. The audio cable was against a power cable and the power was causing noise in the audio. I know this has been documented before, you just have to look for it. Some people re-routed their cables all together to get rid of this. Is yours a new run or an original? Ours is one of the first 100 RR.
Mine is number 255. I think I remember it making some noise before, but not this bad. I don't think I moved other cables around when replacing the 2 lightboard cables, can't help wondering if maybe the cables they sent aren't shielded and that's causing it? Will try re-routing cables around and see what that does.
I chased this down on numerous occasions moving cables and reconnecting anything to do with sound. No luck- gave up. The sound was definitely related to the LEDs because it changed along with the attract mode lighting.
I had the same issue. Here’s a thread with great info on how to solve it:
