Hi all! Brand new Pinsider. I have SouthPark, and just ran into a DMD issue I have been unable to solve. Upon startup, the DMD will flash Sega Pinball SouthPark, and the A # version. After that, the display goes blank. The ribbon cable between the game’s main board and the DMD seems to be ok. It has kinks, but after checking it (lead to lead, point to point) with a multimeter, all the wires in the ribbon read out appropriately. I checked the most suspect ones (closest to kinks) for shorts, but each showed O/L. After doing my best to verify that the ribbon was good, I reinstalled it. After powering up the game, I tapped and moved the ribbon around, but nothing caused the DMD to change state from the blank screen.
Next, I reseated the ROM on the back of the DMD—but to no avail.
A little background—this is the upgraded color DMD. The DMD control card appeared to be in great shape, and is relatively new. The pinball machine, including the updated color DMD, has worked perfectly for the past year. The only exception to the statement above is when the DMD froze up on me a couple of days ago mid-game. I turned it off and back on, and voila, the game went right back to normal.
Despite power resets here though, I cannot get the display to work after the original flash showing Sega and the version #.
Thank you for your time and help!
