I blew the regulator on mine, you can not get to the solder side, so I surface mounted a new one soldering wires to what I could....been working good for a few years now. Keep an eye out for a WMS "Dotmation" slot machine, they use the same DMD. I actually just passed on one for $100 recently (It was an "X Factor", I have that slot and that game burns in bad on the Dmd... Anyway, those slots usually go cheap when the PS craps out ( easy fix), but good score for the Dmd.
