I have a LAH that is having DMD issues. All the pixels are lit. Doesn’t display the display version at start up. Game plays fine, just no display. I reseated connectors, tested voltages on dmd board and dmd. It did flash once while testing and showed high score 2 in attract mode. Display board maybe?

Check all the ribbon connectors again. Make sure there isn't one end somewhere that is plugged in, but off by one row. You may have to look at the boards from another angle to see it.

Thanks, I’ll check that. The machine worked fine a month ago, then I turned it on yesterday without touching any of the ribbon cables or boards and it does this.
