Quoted from smiley:Try reseating the connectors on all boards.
Beat ya to the punch. I gave all the connectors a good reseating, including the ribbon cables. The DMD was also in known good working order with no visible dark spots or ghosting before the game stopped booting, so I'd be surprised if it was the display itself that conked out, but anything's possible I guess. Gotta do a little more testing with the multimeter when I have some free time but after reading what I can find on the internet, it seems like I might have some dead transistors/some burning going on maybe
