Williams DMD hum / noise

[Andypc]

Hi, I am fairly new here and picked up my first pinball yesterday (Williams Indiana Jones) IJ . One scary moment when we realised the previous owner didn't have any wing bolts in to secure the backbox and he had been playing it like that for 10 years!

One issue that I would like to resolve is the fact there is fairy loud humming / noise when the DMD is fully illuminated. Any idea what I might need to change / fix?

nothing unusual with a noisy display just play and enjoy

Noisy displays are not unusual. It’s worth checking that all the pcbs in the back are screwed down properly to ensure good earthing. If it persists don’t worry about it.
