I just turned on my DE Star Wars pinball after not using it for a few weeks and I noticed that the DMD did not display anything for around 15 seconds after the machine started. Everything else looks to be ok and starts except for the display.

The machine has a reasonably new Xpin power supply so I don’t think it is an issue from there. This is the first time I have noticed this issue so thought I would see if anyone else has had the same issue so I can fix before it gets worse.

I was guessing it could be something on the DMD controller boards but not really sure where to start looking. Thanks in advance.

Sounds to me like the dmd is nearly dead, once they warm up they will start working again . Be careful as it will be drawing more current than normal and might damage the high voltage section of the controller , I recommend you try another machines dmd if you have one available to confirm this.

I agree as it sounds like it is dying. Best to test the DMD in another game.

Good news. You can put in a ColorDMD and no longer worry about the high voltage either.

Hmmm, I’ve noticed mine do the same thing on occasion. Also with a relatively new xpin power supply. I’ll have to do some investigating (or wait for someone to post the answer here

Any mods in the game? Does you JP or LAH have a Xpin power supply?

From my experience with my LW3 it is normal for the DMD to occasionally not light up immediately on power up. I can't say why but its been like that for over 2 years without any problems whatsoever. The DMD just skips over showing the ROM versions of the CPU and display driver and FREE PLAY or PRESS START is the first thing to be seen. LW3 has the exact same board set as Star Wars. I wouldn't worry about it.

Thanks for everyone’s responses and I hope it’s not on it’s way out although that is the joy/headache of owning a 90s pinball. I will keep an eye on it as it is only the first time I have seen it. I don’t have any mods on my SW and all my other DE machines all have original boards.

It sounds exactly like the issue mikat11 has with their LW3.

Will see what happens and if needed it is a good excuse to get a ColorDMD.

With 3 games having the same game boards, you can easily swap to find out which is causing the issue. Might be easier to swap the whole speaker panel to start with, which will be the DMD and the DMD controller board.

Quoted from PinballManiac40:

I will switch the DMD's around on the weekend to see if I can replicate the issue.
