Hello, So I just slapped a new display power supply in as the last one was found bad after troubleshooting. Upon installing the new one I get some dmd output, see attached pic. You can almost make out the whole startup screen and in will go through a few images like the actor julians image. They then fade out to dark until it loops back around to julian again. It seems all of the different dots will light up. I have reseated all of the connectors and everything looks good.

Any ideas on what to look for next?

Maybe I just need to reset the chips? Not sure of technique.

I found something about reflowing the input and outputs on the board looking on my phone but can't find this thread again.

Thank you!!

You DMD is outgassed and needs to be replaced. There is no fix. My The Lost World Jurassic Park had a DMD with very similar issues, video attached. I swapped power supplies and cables, etc, but not until I tried a different DMD did it go normal. The good news is that you should be able to find a display for less than $100, or you could splurge and get a ColorDMD. I'd recommend the LED version given the Showcase backbox that your Sega has. Also, here is a link to my resolved issue thread.

Any other DMD games do you have to try it in?

You could buy a Sigma LED ColorDMD. You can choose any color it to be until the full color ROM gets released.

I only have a vacation america right now and this, pretty silly combo of games. I will look at this option. X files is pretty beat up but will be a good player. Just not sure how much I should sink into it.

Cool. Good luck. If there is a pinball community around you there is usually someone with an extra display to sell. If not, there is someone here in Seattle that I could probably hook you up with. I had an extra DMD to put in The Lost World Jurassic Park from a Tales from the Crypt that I installed a ColorDMD into.

Have fun getting back into pinball. I'm just finishing up that JPLW and next is refurbishing World Cup Soccer. Both of these came in container buys from Italy, which are FILTHY and BROKEN!
